<span style="font-size: large;">Not every crack is a defect, as cracking in pool coping and tile grout is completely normal.</span><br />
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><b><u>Tight cracks</u></b></span><br />
<br />
<span style="font-size: large;">Grout is strictly a cosmetic filler between tiles and coping stones. Grout does not serve any structural purpose, other than to fill the voids between materials. </span><br />
<br />
<span style="font-size: large;">Hairline cracks in the grout between swimming pool copings is totally acceptable. As the grout cures and loses moisture, it shrinks slightly, possibly even pulling away slightly. Combined with the natural expansion and contraction of the coping material, these cracks will develop - GUARANTEED. </span><br />
<br />
<span style="font-size: large;"><span style="font-size: large;">A hairline crack along one side of a joint or through it's length is to be expected. </span>As long as the grout does not begin to crumble, dislodge or decay, hairline cracks are totally acceptable.</span><br />
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">Many new pool owners are alarmed when they observe small hairline cracks in the grout of the copings or tiles. The assertion that grout does not crack inside their residence, does not apply to outdoor materials. Outdoor materials are subject to daily 30-50ºF temperature swings, while indoor materials are in a shaded and climate controlled environment.</span><br />
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><u><b>Decay</b></u></span><br />
<br />
<span style="font-size: large;">Of course, grout that is crumbling or dissolving is defective and should be removed and replaced. </span><br />
<br />
<span style="font-size: large;">Exposure to extreme temperature differentials may cause grout to spall - that is, a surface flaking. This is usually an indication of some compressive forces at play. It may be due to thermal expansion or from differential movement. After an initial replacement, the defect reoccurs, then that joint should be replaced with a flexible construction sealant.</span><br />
<br />
<span style="font-size: large;">Not every crack is a defect.</span><br />

<span style="font-size: large;">Thermal shock and expansion causes shattered, cracked and spalled glass tiles.</span><br />
<br />
<br />
<span style="font-size: large;">Many of the glass tile manufacturers have yet to produce products that meet the ANSI A137.2 performance standards. </span><br />
<br />
<span style="font-size: large;">Why? It is less expensive to simply replace any cracked tiles with new tiles, than it is to manufacture and perform testing to ensure compliance. The manufacturers know that they can also deflect many failure warranty claims by blaming the installation process. </span><br />
<span style="font-size: large;">They will quickly point out the installers failure to install expansion joints as the cause of any failure. And the manufacturers will continue to refuse to produce products that are compliant with the standards they wrote.</span><br />

<tr><td class="tr-caption" style="text-align: center;">Boyce & Bean glass tiles (manufactured by Crossville)</td></tr>
</tbody></table>
<span style="font-size: large;"><br /></span>
<span style="font-size: large;">The ANSI standards state that any glass tiles that do not meet the thermal shock resistance standard, cannot be specified for use outdoors. In fact, they are relegated to use in dry indoor wall applications only (kitchen back splashes and decorative walls).</span><br />
<br />
<span style="font-size: large;">The manufacturers want to have their cake and eat it to.... they refuse to create compliant products, but they will blame an installer for failing to comply with the installation standards.</span><br />
<br />
<span style="font-size: large;">Shouldn't glass tile manufacturers comply with their own industry standards?</span><br />
<br />
<span style="font-size: large;">Or be forced to stop marketing non-compliant glass tile as being suitable for outdoor and swimming pool applications?</span><br />
<br />

</span><span style="font-size: x-large;"><u><b><span>New
Regulations</span></b></u></span><br />
<br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><span>OSHA
has established new permissible exposure limits (PELs), which were last
evaluated in the 1970’s.<span> </span>Workers'
exposures are now limited to a new PEL of 50 micrograms of respirable
crystalline silica per cubic meter of air (μg/m<sup>3</sup>), averaged over an
8-hour day.<span> </span></span></span><br />
<span style="font-size: x-large;">
</span><br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><u><b><span>Who
is affected by these Rules?</span></b></u></span><br />
<br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><span>Everyone
has a duty and responsibility to reduce silica dust exposure.<span> </span>Even if you do not have direct employees, you
are responsible for work place safety on your projects.<span> </span>You are liable for worker injuries, if you
are aware of and allow unsafe working conditions to occur/continue.<span> </span>As a direct employer, you obviously are
responsible for the safety of your employees.</span></span><br />
<br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><span>Because
Silicosis oftentimes manifests itself well after silica exposure, you may
experience employee claims years later.<span>
</span>Then it is too late and impossible to document PEL’s and employee
exposures.<span> </span>It is best to have a written
exposure reduction policy, provide the proper respiratory protection and have
employees sign acknowledgement forms.</span></span><br />
<br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><span>Because
it is virtually impossible for construction managers to monitor and document
the precise PEL’s on various outdoor job sites, it is best to institute a personnel
protection plan that includes reducing generated silica dust and the use of
approved respiratory protection devices.</span></span><br />
<br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><u><b><span>Particulate
exposure</span></b></u></span><br />
<br />
<span style="font-size: x-large;">
</span><span style="font-size: x-large;"><span>As
a matter of work place safety, the exposure to all inhaled dust and particulate
matter should be controlled.<span> </span>Many other
swimming pool products such as diatomaceous earth, powdered chemicals and
common dirt & dust are also proven lung irritants.</span></span><br />

<span style="font-size: large;">Highly UNLIKELY!</span><br />
<br />
<span style="font-size: large;">"I'm allergic to chlorine." Doctors, pool service technicians and allergists hear this all of the time. However, a careful evaluation of the patient will actually reveal that this "allergy" is in reality a reaction to:</span><br />
<br />
<span style="font-size: large;">a. Improper pH levels</span><br />
<span style="font-size: large;">b. Out of balance water chemistry</span><br />
<span style="font-size: large;">c. Chloramines (the result of poor water chemistry)</span><br />
<br />
<span style="font-size: large;">Does the patient itch when they shower or bathe at home?</span><br />
<span style="font-size: large;">Almost every water system in the United States is sanitized with chlorine. In fact, there is a measurable amount in almost all tap water.</span><br />
<br />
<span style="font-size: large;">The itching or "chlorine" odor on the skin following swimming is most likely chloramines that have formed on the skin (formed when the chlorine came into contact with sweat).</span><br />
<br />
<span style="font-size: large;">Does the patient experience an allergic reaction (thoracic inflammation or respiratory distress) when they drink tap water?</span><br />
<span style="font-size: large;">If they were allergic to chlorine, ingesting an allergen would result in a reaction - especially when applied directly to the mucus membranes in the thoracic area.</span><br />
<br />
<span style="font-size: large;">Burning eyes when they swim in a chlorinated pool? If their eyes do not burn when subjected to drops of tap water, then the pH of the pool was probably out of balance.</span><br />
<br />
<span style="font-size: large;">Medical doctors who do not understand the science of swimming pool water chemistry and chlorination will simply agree with the patient. </span><br />
<br />
<span style="font-size: large;">Just because it "smells like chlorine" DOES NOT MEAN THAT IT IS CHLORINE. </span><br />

<span style="font-size: x-large;">When a consumer misuses a product and causes damage, it is not a manufacturer's defect or valid warranty claim.</span><br />
<br />
<span style="font-size: x-large;"><u><b>Automatic Pool Cover</b></u> </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">After recently completing swimming pool project with an automatic cover, a client called to request a warranty service call. Apparently the cover track and glide mechanism were not working properly.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Upon further inquiry, the client's children were "testing" the cover by running and playing on top of the cover. They also operated the cover while as child sat on it.</span><br />
<br />
<span style="font-size: x-large;">Our instructions to the owners were very clear - NO walking or climbing on the cover, DO NOT operate with any excess load on the cover (standing water, cover pump, etc.), DO NOT operate the cover with people in the pool. In addition, we went through the manufacturer's use and instruction manual with the client - in detail.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Safety Device</b></u></span><br />
<br />
<span style="font-size: x-large;">Automatic safety covers are <i>safety devices. </i> They are not meant to double as usable surfaces or load bearing floors.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The safety cover is intended to support the weight of a person in the event of an accidental fall onto the cover. The cover is supposed to prevent a person from coming into contact with the water underneath. It functioned as intended - no one came into contact with the pool water.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Damage to an automatic pool cover from people walking, running, playing or jumping on them are not warranty items.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: large;"><span style="font-size: x-large;">You wouldn't drive your car into a wall to test the airbags, then claim a warranty defect when they deploy !</span></span><br />

<span style="font-size: x-large;">Recently a client inquired about using ALTOGLASS.COM glass mosaic tiles in their swimming pool. The manufacturer's website promotes their tiles as appropriate for use in swimming pools.</span><br />
<br />
<span style="font-size: x-large;">But a review of the Technical Area on their website (http://www.alttoglass.com/tech.html) on 12/10/2015 revealed that they do not have any test results indicating compliance with ANSI A137.2 - Thermal Shock Standard for Glass Tiles.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Here is a screen shot of the technical data.</span><br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>

<br />
<br />
<br />
<span style="font-size: x-large;">Thermal shock is not even mentioned.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Makes you wonder why it is not mentioned, since the thermal shock standard has been in existence for a few years?!</span><br />
<br />
<span style="font-size: x-large;">How can we endorse a product for use in our projects, if it does not meet their own industry standards? </span><br />

<span style="font-size: x-large;">Recently another tile manufacturer asked us to review a claim of defective tiles. </span><br />
<br />
<span style="font-size: x-large;">The pool owner's representative was making an assertion that the ceramic tiles on the top of a spa dam wall were defective, as the glaze was changing colors due to UV and chemical exposure.</span><br />

<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">After reviewing the images of the tiles, immediately following their initial installation and present day, it became readily apparent what the cause of the discoloration was.<span id="goog_226695534"></span><span id="goog_226695535"></span></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Efflorescence (or mineral build up) is not considered a defect. It is a due to the lack of routine removal of mineral build up. Much like the waters spots that form on dishes or glassware in a dishwasher, this mineral build up does not mean that the dishes or glassware are defective. Some efflorescence may be coming from the grout or thinset. But in any case, the tiles are not defective. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Special cleaning services are available that will remove calcium and mineral build up. Most pool service companies offer these services at an additional charge. Routine weekly brushing of the tile will not prevent mineral or calcium build up, so the pool service is not to blame either.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">As the water evaporates, it leaves a film of minerals behind. Over time these minerals begin to make the tile appear hazy white.</span><br />
<br />
<span style="font-size: x-large;">Some white efflorescence is even visible in the grout joints, before the pool was even completed.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The solution? Pay someone to remove the mineral build up. It's a maintenance issue!</span><br />

<u><b><span style="font-size: x-large;">Cracked Glass Tile Mosaics</span></b></u><br />
<br />
<span style="font-size: x-large;">There are thousands of firms jumping onto the glass tile bandwagon.
Of course they all want to sell to the pool industry - 1 tile pool is
equal to 1000 tile showers or kitchen back splashes. </span><br />
<br />
<span style="font-size: x-large;"> This past
week, a client and their interior designer showed me some glass tiles
from a national tile distributor. They were told that they "are
approved for swimming pools." The client wanted to move ahead. I forewarned them, that unless the tiles had passed the tile industry's own thermal shock standards, that we would not touch them.</span><br />
<br />
<span style="font-size: x-large;">When I contacted the distributor's
technical services department, they advised that the tiles had not been
tes<span class="text_exposed_show">ted for compliance with ANSI A137.2.</span></span><br />
<br />
<div class="text_exposed_show">
<span style="font-size: x-large;"> It is imperative that swimming pool designers and contractors not be lured by false promises and claims of marketing departments, salespeople and showrooms. Yes, you can install anything in a pool, but not everything is durable enough!</span><br />
<span style="font-size: x-large;"><br />
INSIST that any glass tile you specify or install, has been tested and
is in compliance with ANSI A137.2. It outlines the durability
requirements, and most importantly, the tile's resistance to thermal
shock.</span><br />
<br />
<span style="font-size: x-large;"> WARNING: There are many name brand tiles that do not
comply with ANSI A137.2. Big box stores, fashion designers, home
improvement stores and national tile distributors all have private label
brands that do not meet the standards. Great for a kitchen back splash
- but not thousands of square feet in a swimming pool !</span><br />
<br />
<span style="font-size: x-large;"> REMEMBER
- DO NOT take anyone's word for it. Ask to see the test results from
an independent U.S. testing laboratory. Those that have submitted their
products for testing are more than happy to provide you with a copy!
And they should be proud of it!</span><br />
<br />
<span style="font-size: x-large;"> For an article that explains ANSI A137.2 check out this link:</span> <span style="font-size: x-large;"><a href="https://www.tcnatile.com/image/pdfs/IntroducingANSIA137.2.pdf" rel="nofollow" target="_blank">https://www.tcnatile.com/ima…/pdfs/IntroducingANSIA137.2.pdf</a></span><br />
<br />
<span style="font-size: x-large;">
If a firm wants to sell products to our industry, shouldn't they at
least conform to the MINIMUM standards in their own industry ??</span></div>

<div style="text-align: left;">
<span style="font-size: x-large;">California Appliance Energy Regulations ( California Code of Regulations, Title 20, Sections 1601-1609), now restricts the sale of inefficient and antiquated pool pumps and replacement motors.</span></div>
<div style="text-align: left;">
<span style="font-size: x-large;"><br /></span></div>
<div style="text-align: left;">
<span style="font-size: x-large;">Effective July 1, 2015 it is illegal and punishable by a $2500 fine, to install a pool pump motor that is split phase or a capacitor start - induction type. 1 HP and greater motors shall have multi-speed capabilities (two or more speeds).</span></div>
<div style="text-align: left;">
<span style="font-size: x-large;"><br /></span></div>
<div style="text-align: left;">
<span style="font-size: x-large;">With the advent and popularity of variable frequency drives (VFD), variable speed pumps have proven themselves as more energy efficient - even when operating at their maximum speeds.</span></div>

<span style="font-size: x-large;">There has been a lot of interest in chlorine free pools. Chlorine has been given a bad rap and is not usually to blame for the public's health concerns. Regardless, the quest for chemical free pools continues. And, yes they can be achieved.</span><br />
<br />
<span style="font-size: x-large;"><u><b>Chlorine Free</b></u> </span><br />
<br />
<span style="font-size: x-large;">There are two concerns with keeping swimming pools clear and healthy for bathers. </span><br />
<br />
<span style="font-size: x-large;">The first is a sanitizer - something to kill germs and bacteria. What ever is used, it must remain present in the water 24 hours a day, every day. There must be enough already in the water or available for injection to handle spikes in temperature and bather loads.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The second is something to function as an algaecide. The most effective algaecides are heavy metal ions such as nickle, copper and silver. In microscopic doses, they work well and are safe for the environment. However, there is no easy means to measure the levels of these metals.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Ionizers</b></u></span><br />
<br />
<span style="font-size: x-large;">There are a number of ways to get heavy metals into your pool water. </span><br />
<br />
<span style="font-size: x-large;">Pouring in an algaecide that contains these metal compounds is the fastest. There are many on the market. However, they result in a large dose of metals.</span><br />
<br />
<span style="font-size: x-large;">Erosion ionizers are cartridges that contain heavy metal compounds that gradually emit metals into the water as the water passes through them. Cartridge balls can be placed in the skimmers or pump baskets, or in-line cartridge dispensers can be plumbed into the pipes (like an oil filter). </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Active ionizers are electronic devices that use electricity to emit metal ions into the pool water. These are always plumbed into the pipes at the equipment pad.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Contrary to manufacturer's claims, metal ions do very little to kill bacteria and germs. They work so slowly on killing germs and bacteria, they are only relied upon to keep algae and plant life at bay.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Ozone</b></u></span><br />
<br />
<span style="font-size: x-large;">Ozone is the best form of germ and bacteria killer used in swimming pools. Ozone also breaks down contaminates that bathers introduce into the water - fabric softeners, cosmetics, suntan lotions, soap and shampoo residues, etc. </span><br />
<br />
<span style="font-size: x-large;">A properly sized ozone side stream system can cost $10,000. As the size of the pool increases, the cost rises exponentially, as they are sized to match the size of the pool and the bather load. </span><br />
<br />
<span style="font-size: x-large;">Ozone is gas that is very reactive and therefore has a very short half life. Because it does not last, it </span><span style="font-size: x-large;"><span style="font-size: x-large;">cannot be bottled and </span>must be manufactured on site. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Ozone is thousands of times more effective at killing microorganisms that chlorine. Due to it's short half life, ozone only remains in the water while it is actively being produced. Shut off the ozone generator and within minutes, the ozone in the water is gone.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Ultraviolet Light (UV)</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Ultraviolet light kills germs and microbes using the radiation that exists in UV light. It does not emit any residual sanitizer into the water.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Because it requires a light source, a device is plumbed at the equipment pad. The water passing through the device is exposed to the UV light, killing the organisms. The pumps must be operating for the UV lamps to operate. And only that amount of water that can pass by the lamps is treated. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Truly Chlorine Free</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">To truly achieve a chlorine free pool requires that an OVER SIZED corona discharge ozone system be ran 24/7. If complemented by a UV system, a chlorine free pool could be achieved.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">But it requires that the circulation pump be operated 24 hours a day, everyday. And it has associated costs - the equipment, maintenance and electricity.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Ultra-Low Chlorine Pool</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">By contrast, one could operate a properly sized ozone system with UV for 6-8 hours per day... provided that they maintained a very low level of chlorine.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">That chlorine level could be so low, say 0.5 ppm (parts per million) and still maintain clear sanitized water. To keep the chlorine precisely at such low levels would require an ORP/pH controller to micro-dose the chlorine. As demands increased or decreased, the controller would adjust it's output to maintain 0.5 ppm.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">0.5 ppm of chlorine is approximately the level in found in drinking water. </span><br />
<br />
<span style="font-size: x-large;">Safe for human consumption and even for watering plants!</span><br />

<span style="font-size: large;">The proposed ANSI/APSP-15 American National Standard for Residential Swimming Pool and Spa Energy Efficiency is nothing more than another misguided attempt at justifying improper hydraulic designs.</span><br />
<br />
<span style="font-size: large;">The "Residential Energy Efficient Swimming Pool Rating System" will assign <i>points </i>a pool or spa hydraulic system for the size of the pipes, style of elbows used, type of pump installed and size of the filter. These points will be applied towards the energy efficiency rating of the vessel. Vessels will be rated Gold, Silver or Bronze.</span><br />
<br />
<span style="font-size: large;"><u><b>Separate the forest from the trees</b></u></span><br />
<br />
<span style="font-size: large;">On a properly designed hydraulic system all of the components are already compatible and in balance with each other. This includes the pipe sizing, fittings, filter sizing, pump style and flow rating, flow rates, turn over rates, line velocities, pump curve and the total dynamic head.</span><br />
<br />
<span style="font-size: large;"><u><b>The Bottom Line </b></u></span><br />
<br />
<span style="font-size: large;">Properly designed plumbing systems that operate within the acceptable line velocity standards and in the center of a pump's efficiency curve (pump curve) ARE AS EFFICIENT AS THEY WILL EVER GET.</span><br />
<br />
<span style="font-size: large;">Only utilizing alternative energies to heat and operate a pool will reduce the operating expenses and energy consumption. Using pumps equipped with Energy Star or VFD motors will also reduce electrical consumption.</span><br />
<span style="font-size: large;"><br /></span>
<span style="font-size: large;"><u><b>True Energy Efficiency Ratings</b></u></span><br />
<br />
<span style="font-size: large;">Energy ratings for a vessel should be calculated by a formula of it's hydraulic efficiency, gallons per minute flow rate and</span><span style="font-size: large;"> actual kilowatts consumed to move that water.</span><br />
<br />
<span style="font-size: large;">Poorly designed hydraulics, undersized pipes and filters, substandard plumbing and workmanship, inefficient motors and mismatched components will have a detrimental effect on the calculation. Assigning "brownie points" for doing things correctly should not factor into the equation.</span><br />
<br />
<span style="font-size: large;">Vessels should be PASS/FAIL based upon a set standard (around the 80-85 percent level). </span><br />

<span style="font-size: x-large;">Prior versions of the National Electric Code (NEC) forbid the installation of low voltage landscape lighting within 10 feet of the water's edge. The 2014 NEC has made changes to Section 680 to allow landscape lighting to be located less than 5 feet from the water's edge, with certain conditions.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>2014 NEC Changes</b></u></span><br />
<br />
<span style="font-size: x-large;">First of all, the light fixture must be of a design that does not require <i>GROUNDING</i> (that third green internal conductor in the power cord). The new provision does not address metal light fixtures, but assume that if it is metal, that it will need to be externally BONDED to the grid. Bootleg or homemade bonding attachments are not permitted, so if it is not supplied by the manufacturer, then that fixture is probably not permitted.</span><br />
<br />
<span style="font-size: x-large;">The conductors must be ran inside of a conduit - direct burial near the pool is forbidden elsewhere in the NEC. Granted, at the end, the conduit must stub up to allow the wire to exit. A compression seal on the end of the conduit will secure and seal the cord's exit. </span><br />
<br />
<span style="font-size: x-large;">Buried wire nut or underground connections are also forbidden. All of the electrical connections must terminate in an approved pool lighting junction box. A typical above grade pool lighting junction box would work fine. One can also use an in-deck junction box, provided it is filled with re-enterable potting compound to prevent water entry.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The transformer must be specifically rated and listed for low voltage lighting around swimming pools (not just fountains). If you utilize a transformer designed for underwater 12 volt pool lighting, then you're guaranteed success.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Local Adoption - Lead Time</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Thought the 2014 NEC has been approved on the national level, regional and local authorities usually operate on versions that are 1 or 2 generations older. This is because their government councils have not adopted the current versions. Local authorities have the options of not accepting code changes or making the code more restrictive. So, before specifying or installing lighting close to the water's edge, be sure to check with the local building department.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Reference:</span><br />
<span style="font-size: x-large;">NEC 2014, Section 680.22(B)(6) states: “Low-Voltage Luminaires. Listed low-voltage
luminaires not requiring grounding, not exceeding the low-voltage
contact limit, and supplied by listed transformers or power supplies
that comply with 680.23(A)(2) are permitted to be located less than 1.5 m
(5 ft) from the inside walls of the pool.” </span><br />
<span style="font-size: x-large;">NEC 2014, Section 680.23(A)(2) states
that transformers used for low-voltage lighting around pools shall
incorporate isolated windings with an ungrounded secondary and a
grounded metal barrier between the primary or secondary or double
insulation between the primary and secondary windings and shall be listed for swimming pool lighting.</span><br />

<span style="font-size: x-large;">Why your indoor pool project requires an aquatic consultant who specializes in indoor pools.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Learning Curve</b></u></span><br />
<br />
<span style="font-size: x-large;">People think that they can invent inexpensive solutions to the issues that plague indoor swimming pools. And, I'm sorry to burst your bubble, but they have all been tried before and they have all failed. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Do not waste your time and money on "things that might work." The key to a healthy and safe indoor pool is dehumidification and controlling vapor transmission.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Vapor Barrier</b></u></span><br />
<br />
<span style="font-size: x-large;"> A vapor barrier exists to prevent the transmission of water vapor (microscopic droplets of water) into the building envelope. Once that occurs, many terrible things happen to the building and occupants:</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">black mold</span><br />
<span style="font-size: x-large;">corrosion of wiring</span><br />
<span style="font-size: x-large;">rusting pipes</span><br />
<span style="font-size: x-large;">dry rot </span><br />
<span style="font-size: x-large;">short circuit of electrical components</span><br />
<span style="font-size: x-large;">water damage</span><br />
<span style="font-size: x-large;">soggy drywall</span><br />
<span style="font-size: x-large;">decay of building fasteners, brackets and structural elements</span><br />
<span style="font-size: x-large;">respiratory problems:</span><br />
<span style="font-size: x-large;"> pneumonia </span><br />
<span style="font-size: x-large;"> asthma</span><br />
<span style="font-size: x-large;"> Legionnaire's Disease</span><br />
<span style="font-size: x-large;"> upper respiratory ailments</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Controlling Vapor</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The main key to controlling the moisture in the air (humidity), is to remove it. While pool covers, temperature control and ventilation are important, together or by themselves they cannot mitigate the water vapor that will emit from the pool. Like gravity, it cannot be prevented or turned off.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">However, once into the environment, the humidity can be controlled. Dehumidifiers dry the air and return the dried into the envelope. Provided the natatorium has a properly installed vapor barrier, the moisture ends there.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Mechanical Engineer and HVAC Contractor</b></u></span><br />
<br />
<span style="font-size: x-large;">You do not want to hire an mechanical engineer or HVAC contractor who is not experienced with indoor pools. Though there are many reference sources available for them, you do not want them learning or experimenting on your project. </span><br />
<br />
<span style="font-size: x-large;">This is as much as a science, as it is an art. Though dehumidification ducting and systems may be sized properly, installing the registers, returns or controls in the incorrect location will negate the efficiency of the entire system.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>It's been done before</b></u></span><br />
<br />
<span style="font-size: x-large;">Because you don't want to spend the money on a dehumidification system, don't think that you have struck upon an alternative solution.</span><br />
<br />
<span style="font-size: x-large;">Every "bright idea" has been tried:</span><br />
<span style="font-size: x-large;"> skylights</span><br />
<span style="font-size: x-large;"> sliding doors and windows</span><br />
<span style="font-size: x-large;"> heaters</span><br />
<span style="font-size: x-large;"> pool covers </span><br />
<span style="font-size: x-large;"> A/C vents </span><br />
<span style="font-size: x-large;"> fans</span><br />
<span style="font-size: x-large;"> Heated glass</span><br />
<span style="font-size: x-large;"> screened rooms </span><br />
<span style="font-size: x-large;"> moveable hydraulic floors</span><br />
<span style="font-size: x-large;"> heated pool decks</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The ONLY solutions to controlling the humidity in the room are a dehumidification system, building an outdoor pool or leaving the pool empty.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Experience can save you a bundle on the learning curve.</span><br />

<span style="font-size: x-large;">You are considering building your own pool and being your own contractor. You have located a "pool construction consultant" who professes to save you thousands of dollars. They even call themselves a "pool builder."</span> <br />
<br />
<span style="font-size: x-large;"><u><b>Hidden Dangers</b></u></span><br />
<br />
<span style="font-size: x-large;">There are many dangers in hiring an unlicensed "consultant" to assist you to build your own pool. The potential pitfalls of hiring a DIY swimmingpoolbuilders .com type of business are plentiful.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Lack of Insurance</b></u></span><br />
<br />
<span style="font-size: x-large;">An unlicensed "consultant" is trying to escape the expenses of running a lawful and legitimate contracting firm. They do not have the expense of liability insurance, let alone being able to qualify for coverage.</span><br />
<br />
<span style="font-size: x-large;">Reputable contractors possess liability insurance to protect you and your property in the event of any calamity. They also possess insurance certificates from each of their subcontractors as well. </span><br />
<br />
<span style="font-size: x-large;">The T's are crossed and the I's dotted! Everyone is protected.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Lack of Licensing</b></u></span><br />
<br />
<span style="font-size: x-large;">Because "consultants" lack the proper licensing, a property owner will have little recourse in the event there are problems. And, as in most construction projects there will be <i>something</i> that goes wrong. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Having a State Contractor's license, means that there is a license bond on file with the state. The State Contractors Board also functions as a consumer protection and enforcement agency, in the event of serious construction defects.</span><br />
<br />
<span style="font-size: x-large;">Licensed Contractors must also qualify of a license. This means that they cannot have prior criminal convictions. They must have years of of practical experience actually building pools. They must pass a tests on contractor's law and business practices. They must also pass a test, ensuring they have a minimum level of knowledge about acceptable workmanship practices of their trade.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">How would you know if the on-line "DIY pool builder-consultant" is a convicted child molester, registered sex-offender, ex-con or has prior convictions for fraud ? </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The State Contractor's Licensing Board only has records available for those firms and persons that possess (or possessed) a Contractor's License. They do not maintain a database of individuals who have been prosecuted for operating without the proper licensing.</span><br />
<br />
<span style="font-size: x-large;">This is all for the consumer's protection. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Liens & Financial Responsibility</b></u></span><br />
<br />
<span style="font-size: x-large;">Licensed Contractors are required to pay their subcontractors and to obtain lien releases from them. These protect the property owner from unpaid subcontractors placing liens upon their property. Even stale liens can taint the title to a property, making a future sale difficult.</span><br />
<br />
<span style="font-size: x-large;">Licensed Contractors must maintain a minimum level of financial stability, in order to operate a legitimate contracting firm. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Contact Information</b></u></span><br />
<br />
<span style="font-size: x-large;">Licensed contractors cannot hide behind a website. They must publish their physical address, license number, owner's names and their telephone number on all of their web pages and advertisements. They are not allowed to hide in the crevasses of the Internet. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Carefully inspect any "consultant's" website. </span><br />
<span style="font-size: x-large;">Is the name of the responsible person listed?</span><br />
<span style="font-size: x-large;">Is their physical location listed?</span><br />
<span style="font-size: x-large;">Is there a Contractor's License Number shown?</span><br />
<br />
<span style="font-size: x-large;">If this information is not listed, how are you going find them when you have to sue them in court?</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Worker's Compensation Insurance</b></u></span><br />
<br />
<span style="font-size: x-large;">Licensed Contractors can only hire subcontractors that possess the proper workers compensation insurance. They must have copies of these insurance certificates on file before any work begins.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">If a subcontractor does not have the proper workers compensation insurance coverage then the PROPERTY OWNER IS LIABLE for any employee injuries that may occur on their project!</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">If an employee gets cut with a circular saw, falls off a ladder, gets impaled on rebar, becomes buried in a trench, or driven over by a tractor - then the resulting lawsuit and medical bills are the responsibility of the property owner. And all because of the lack of a piece of paper proving insurance coverage.</span><br />
<br />
<span style="font-size: x-large;"><b><u>Crossing the Line </u></b></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">If a "DIY consultant" designs the pool, provides the engineering, specifies the equipment, schedules the subcontractors, gathers the lien releases, sells the equipment, performs periodic inspections of the work (either in person or via digital pictures) - then they are actually performing the work of a contractor and a LICENSE IS REQUIRED (CSLB Case #620053266).</span><br />
<br />
<span style="font-size: x-large;">There are many intricacies of building a swimming pool. Overlooking a single item can be catastrophic - even deadly. </span><br />
<br />
<span style="font-size: x-large;">Electrocution, suction entrapment, hair entanglement, incorrect floor shapes and slopes, cracked structures, mudslides, damaged building foundations, generic or mail order structural engineering, broken pipes, corroded rebar and substandard shotcrete/gunite are common construction faults and defects.</span><br />
<br />
<span style="font-size: x-large;"><u><b>The Bottom Line</b></u></span><br />
<br />
<span style="font-size: x-large;">As a DIY owner/builder - Do you know enough about how to build a swimming pool, without asking questions of the subcontractors or idiots on the Internet or DIY websites?</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><i><b>If you answered no, then are you a gambler?</b></i></span><br />

<span style="font-size: x-large;">Bending PVC pipe by heating it to create bends and turns is acceptable, so long as there is NO DISCERNIBLE signs that the pipe was heated.</span><br />
<br />
<span style="font-size: x-large;"><br /><u><b>Brittleness and Weakness</b></u></span><br />
<br />
<span style="font-size: x-large;">The PVC pipe should only be heated to the point where the pipe becomes soft enough to bend it in the desired shape. The pipe diameter should not be reduced or crushed. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The exterior of the pipe should absolutely show no sign that the pipe was heated. There should be no discoloration, burning or melting of the plastic.</span><br />

</tbody></table>
<br />
<span style="font-size: x-large;">Burnt areas of PVC pipes become very brittle and weak. These areas are susceptible to decay and breakage. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">I don't have to tell you the havoc that can be wreaked upon a swimming pool, hillside slope or pool deck if there are plumbing leaks under or within the concrete structures. Plus, they are not easy to repair. The long lasting damage to the pool, property, soils and site are oftentimes irreparable.</span><br />
<br />
<br />
<span style="font-size: x-large;"><u><b>Proper Equipment </b></u></span><br />
<br />
<span style="font-size: x-large;">Using pipe ovens or heat blankets instead of propane torches are temperature controlled methods of heating PVC pipes and conduits.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Failing to keep a torch moving causes burned and scorching of the plastic. Even a building inspector with a pea brain will reject any burn pipe that they observe. </span><br />
<br />
<span style="font-size: x-large;">Don't risk your project to brittle pipes - insist that they be replaced before they are "set in concrete."</span><br />

<span style="font-size: x-large;">Swimming Pool designer solar panels for your aquatic project will extend your swimming season if sized properly.</span><br />
<br />
<u><b><span style="font-size: x-large;">Expectations </span></b></u><br />
<br />
<span style="font-size: x-large;">Do not expect to swim in the dead of winter, because you have solar heating panels. That is usually an unrealistic expectation. Unless of course, you live in a locale that has a moderate climate year around (near the equator).</span><br />
<br />
<span style="font-size: x-large;">Sized properly, solar panels will allow you to start your swimming season earlier and end it later than with an unheated pool.</span><br />
<br />
<span style="font-size: x-large;">Glazed solar panels prevent the wind from blowing across the panels, cooling them off. Their efficiency increases due to the additional protection. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Energy Savings</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Solar panels allow you to wean your pool off of fossil fuels (propane, natural gas) and electricity. Even switching from an electric heat pump will help reduce greenhouse gasses, as most of the United States electricity if from coal and natural gas fired power plants.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">People have even been known to pre-heat their spas using their solar panels. When concentrated in a spa, all of the BTU's from the solar panels can heat it to 100ºF+ . You just need to program your system to switch over the valving, to allow enough time to take advantage of the remaining sunlight.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><b><u>Utilization</u></b></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Swimming pools and spas get more use when they are heated - a proven fact. When they are heated for free by the warmth of the sun, they are even more enjoyable.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Get more use out of your pool... Heat it for free!</span><br />

<span style="font-size: x-large;">It has been well documented that improper installation practices and setting materials can contribute to discoloration of natural stone and stone tile pool decks and patios.</span><br />
<br />
<u><b><span style="font-size: x-large;">Research Setting Materials </span></b></u><br />
<br />
<span style="font-size: x-large;">The installer or specifier should always check with the vendor as to the recommended setting materials and mortar and grout colors. </span><br />
<br />
<span style="font-size: x-large;">If the vendor cannot or refuses to provide specifications, then the specifier should turn to the Marble Institute of America (MIA) or the Ceramic Tile Institute of America (CTIOA). </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Both of these organizations have published field reports and technical papers regarding the proper setting materials and colors for various types of stone and tiles.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><b><u>Correct Setting Materials</u></b></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Some dark setting materials may bleed through lighter porous stones or tiles, creating a clouding, mottling or darkening effect. Dark grouts can absorb into the sides of the tiles, causing a darkening of the edges.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Conversely, light setting materials can also bleed through darker materials, causing a lightening or ghosting effect. Lighter grouts can also bleed into the materials, causing a halo effect around the tile edges.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Some epoxy adhesives have been known to cause stones and tiles to curl or twist.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">So, it is important to research the proper setting materials for your type of stone or tile.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Improper Installation Practices</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Using the incorrect technique when setting some tiles can also contribute to discoloration. If the setting trowel's gauge marks (aka "comb marks") are not knocked down, then water may accumulate in the resulting voids. Water saturating the stone, sill cause discoloration and an irregular clouding.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The best method, is to back butter the tiles after a thorough cleaning. The comb marks are knocked down and the tiles set into the fresh thinset or mortar. This will ensure an almost 100% contact and few, if any, voids.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Protect the Stone</b></u></span><br />
<br />
<span style="font-size: x-large;">It is also a good idea to protect the surface of the stones or tiles with a quality sealer or grout release prior to setting the tiles. This will prevent the edges of the tiles from becoming discolored if grout or mortar gets onto the surface during installation.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">A little knowledge will prevent having to tear out large areas of stone or tile.</span><br />
<span style="font-size: x-large;"> </span><br />

<span style="font-size: x-large;">Efflorescence leaching up through floor tiles, hollow clacking sounds and cracking tiles are usually a result of improper installation practices.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><span><u><b><span>ANSI A108.5 (2005) </span></b></u> </span></span>
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><span>Ceramic tile installation practices are published by the American National Standards
Institute (ANSI). This standards also includes quarry pavers (natural
stone tiles). </span></span><span style="font-size: x-large;"><span></span></span><br />
<span style="font-size: x-large;"><span><br /></span></span>
<span style="font-size: x-large;"><span>ANSI A108.5 - </span><span><span>3.3.2 says that on exterior floors, the average uniform
contact area with the thinset mortar shall not be less than 95%. 3 tiles will be inspected to determine the average coverage and compliance.</span></span></span><br />
<br />
<span style="font-size: x-large;"><span><span>Both the Tile Council of North America (TCNA) and the National Tile Contractors Association (NTCA) have adopted these standards as the minimum acceptable level of performance and workmanship.</span></span></span><span style="font-size: x-large;"></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><span><b><u>Laziness</u></b></span></span>
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><span>Let's face it, humans beings are like electricity and water - they will take the path of least resistance and effort - lazy !</span></span><span style="font-size: x-large;"><span></span><br /></span>
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><span>Trowel marks are actually called "gauge marks." They are used to create a measured thickness of thinset mortar. </span></span><span style="font-size: x-large;"><span><span>Leaving the trowel marks in
place will mean only 50% contact at 100% thickness of the gauge marks.</span></span></span><br />

<span style="font-size: x-large;"> <span>A 1/2 inch comb trowel will leave 3/8 inch </span><span><span>thick layer of thinset, once the grooves are flattened and leveled. This means that to achieve a total of 1/2 inch of thinset, both the substrate and tile will require 1/2 inch trowel marks that are knocked down and smoothed.</span></span></span><span style="font-size: x-large;"></span><br />

<br />
<span style="font-size: x-large;"><u><b>Prefabricated Drain Channels and Covers </b></u><br />
<br />
A mental hurdle that is confusing to most swimming pool builders, designers, state and local health departments, building inspectors and even many drain manufacturers - is the compatibility of gallons per minute (GPM) through the cover and the feet per second (FPS) through an unblockable drain, suction sump or cover or the connected pipes. </span><br />
<span style="font-size: x-large;"> Drain sumps, channels and covers that comply with the national Virginia Graeme-Baker Safety Act (VGBSA) list a maximum GPM flow rating. However, <i><b>it does not</b> </i>mean that the pipe connections below that cover are permitted to flow at that rating. </span><br />
<br />
<span style="font-size: x-large;"><u><b>Pipes have a different standard </b></u><br />
</span><br />
<span style="font-size: x-large;">There are maximum line velocity standards that apply to the connected piping. Simply stated, a 2" pipe can only flow 28 GPM at 1.5 FPS, or 43 GPM at 3 FPS where it connects to a drain sump.<br />
What the GPM drain cover rating allows are the grouping of <i>different suction systems.</i>
Multiple branch lines from different pump suctions may be grouped
together under a cover, until their cumulative GPM flowrate meets the
cover's rating. This allows multiple system inlets to share a drain cover.<br />
Pre-fabricated drain channels pose another design obstacle. They are classified under the VGBSA as "unblockable" drains due to their shape and size. The VGBSA allows these drains to function as a single point suction, meaning that split drains are not required. They can be ordered with various quantities of connection points for plumbing.<br />
Most of these channel drains only provide 2" connection ports that are limited (by law) to a mere 1.5 or 3 FPS (depending on the local standard). <i><b>That equates to ONLY 28</b><b> or 43 GPM per connection</b><b>!</b> </i></span><br />
<br />
<span style="font-size: x-large;"><u><b>Drain Designs </b></u></span>
<span style="font-size: x-large;"> </span><br />
<br />
<span style="font-size: x-large;">1. Single inlet unblockable channel drains are available with 196 GPM ratings. </span><br />
<span style="font-size: x-large;">When installed in compliance with the FPS standard, it only has a maximum flow rating of 28 or 43 GPM. </span><br />
<span style="font-size: x-large;"> </span>
<span style="font-size: x-large;">2. Dual inlet unblockable channel drains are available with 227 GPM ratings. </span><br />
<span style="font-size: x-large;">However, when installed in compliance with the FPS standard, it only has a maximum GPM rating of 56 or 86 GPM.</span>
<span style="font-size: x-large;"> </span><br />
<span style="font-size: x-large;">3. Triple inlet unblockable channel drains are available with flow ratings of 320 GPM. </span><br />
<span style="font-size: x-large;">Yet, when installed in compliance with the FPS standard they are limited to 84 or 129 GPM.</span>
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"> </span><br />
<span style="font-size: x-large;"><u><b>Show me the Math</b></u></span><br />
<br />
<span style="font-size: x-large;">When
you are considering the purchase of a swimming pool, require that the
hydraulic calculations (head loss and line velocities) and the plumbing schematics (line drawings) be included in the plans. Require that the builder note in the plans or specifications, the pipe sizes and the maximum allowable line velocities of branch, trunk and return piping. <span itemprop="description"></span> </span><br />
<br />
<span style="font-size: x-large;">This will ease in the verification of the system performance and compliance, by any project inspectors or consultants. The next hurdle is getting them to actually build it that way!</span>
<span style="font-size: x-large;"></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">The
design of swimming pool circulation and piping systems are not rocket
science. But, it does require that one be familiar with the basics of
hydraulic design, the idiosyncrasies of the codes, what component ratings <i>really mean</i> and the limitations of those components.</span><br />

<span style="font-size: x-large;"><u><b>Salesman vs Designer</b></u></span><br />
<br />
<span style="font-size: x-large;">A salesman will initiate the meetings with the "how's" of what his firm does. The excavation, the form work, the steel and concrete, the pumps and equipment. Though these are important, more important to the design of your project are the "why's."</span><br />
<br />
<span style="font-size: x-large;"><b><u>Pretty Picture</u></b> </span><br />
<br />
<span style="font-size: x-large;">Get beyond the pretty picture. A designer will discuss with you the important elements of design - "the why's."</span><br />
<br /><span style="font-size: x-large;">Design themes and principals such as proportion, scope, scale, symmetry, balance, texture, color, light and shadows. The proper utilization of these principals can set various </span><span style="font-size: x-large;"><span style="font-size: x-large;"> ambiances and </span>moods, create functionality and form, and establish themes and scenes.</span><br />
<span style="font-size: x-large;"><br /></span>
<u><b><span style="font-size: x-large;">Education and Training</span></b></u><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">An educated designer will draw upon their vast knowledge and experience, to create that expensive luxurious looks for everyday people. The use of common materials in new and insightful ways will bring a fresh look to the project of a budget conscious client.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Even those on a budget, should utilize the services of a watershape consulting firm... the few dollars spent up front will save them a fortune later. They may even end up with a Ferrari for the price of a Corvette!</span><br />

<br />
<span style="font-size: x-large;">Maximize your floor space and the utility of your real estate with a moveable pool floor.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Outdoors</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">In regions of the country where every inch of real estate is considered prime, a moveable pool floor makes total sense.</span><br />
<br />
<span style="font-size: x-large;">Real estate is not lost to a pool, as the moveable pool floor can support people and furniture. In, fact people will not even know that there is a pool beneath their feet.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Limited Space</b></u></span><br />
<br />
<span style="font-size: x-large;">In many urban centers, such as Manhattan, London, San Francisco, London, Barcelona, Hong Kong, Palo Alto and the UAE, townhouses and highrise apartments have properties that cannot accommodate an outdoor pool.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">A basement pool with a moveable floor is the ideal solution. You will not lose any rooms for the pool, and you will maximize the utility of that space.</span><br />
<br />
<span style="font-size: x-large;">The moveable pool floor will also assist in controlling humidity and heat loss.</span><br />
<br />
<span style="font-size: x-large;">Indoors, the moveable floor can double as a dance floor or game room. No one will know that there is a pool beneath their feet. </span><br />
<span style="font-size: x-large;"><br /></span>
<u><b><span style="font-size: x-large;">Safety and Security</span></b></u><br />
<br />
<span style="font-size: x-large;">When closed the moveable floor provides the utmost in safety and security. Accidental access to the pool is impossible.</span><br />
<br />
<span style="font-size: x-large;"><u><b>Freedom of Shape and Design </b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Pools with moveable floors are not limited to square or rectangle shapes. Additionally, there is no limitation on the size of a pool with a moveable floor - they can exceed Olympic swimming pools!</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">A pool with a moveable floor does not increase the footprint of the pool, only it's depth. Additional space must be provided beneath the pool for the lifting system.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">A rooftop pool will drop into the space below. Additional structural members will be required to support the load of the pool and the mechanical systems.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><i><span style="color: yellow;">If you can dream it, we can design and build it!</span></i></span><br />
<span style="font-size: x-large;"><i><span style="color: yellow;">Worldwide design consultation and construction management.</span></i></span><br />

<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>NEC 680</b></u></span><br />
<br />
<span style="font-size: x-large;">Though section 680 deals specifically with swimming pools and spas, this is not the only section that applies to swimming pools. This is where most swimming pool builders, watershape consultants, aquatic designers and even pool equipment manufacturers stumble. </span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">They fail to familiarize themselves with the rest of the NEC, and those sections that also apply to swimming pools.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Major Failing</b></u></span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">One major failing of pool pump manufacturers and pool contractors who install these pumps, is the failure to provide notice of the requirement for or the installation of, the appropriate <i>service disconnect.</i></span><br />
<br />
<span style="font-size: x-large;">The NEC states that any permanently installed motor larger than 1/2 horsepower (data plate rating), may not utilize the circuit overload interrupted (aka: circuit breaker) as the service disconnect [NEC 430.109(B)].</span><br />

his sacrifices have positively impacted the lives of those he comes into
contact with. My trivial problems and ailments pale to those of
Brian's.</span></span><br />
<br />
<span style="font-size: x-large;">Since starting this project, Sgt. Brian Jergens, U.S. Army Ret. and his wife Jennifer have become good friends.</span><br />
<br />
<br />
<span style="font-size: x-large;">When I'm in town, I do not mind receiving text messages "Starbucks?," where I work on my laptop and he reads and hangs out. I know that he just wants to get out of the house. Sitting around all day can drive one stir crazy.</span><br />
<br />
<span style="font-size: x-large;">I've tried to break the monotony of his days, by challenging him to take his on-line hunter's safety exam, taking him flying and introducing him to friends who's schedules allow them to just "hang out with him." Though he still has lingering medical issues and daily challenges, he continues to persevere. </span><br />
<span style="font-size: x-large;"><br /></span>

<b><u><span style="font-size: x-large;">Why do you need a swimming pool designer?</span></u></b><br />
<b><u><span style="font-size: x-large;">http://aquatictechnology.com/design_services.htm </span></u></b><br />
<span style="font-size: x-large;">Most architects and landscape architects are not versed in the requirements of swimming pool construction, technology, hydraulics or the space requirements of the support equipment.</span><br />
<u><b><span style="font-size: x-large;"><br /></span></b></u>
<span style="font-size: x-large;"><u><b>Shoehorning an Elephant into a Gopher Hole</b></u></span><br />
<span style="font-size: x-large;">By hiring a swimming pool designer during the conceptual phase of developing plans for a home or yard, you will save yourself a lot of money. How can spending $3000+ on a swimming pool designer save me money, you ask?</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">If an architect or landscape architect is allowed to run amuck creating a design based upon their limited knowledge of pools, then you will find yourself spending even more money and aggravation redesigning the project <i>that you thought was complete</i>. The resulting project will be a compromise of what you really wanted. Why not get exactly what you want?</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Oftentimes, the structure of the pool or features an architect sold the client on, can not be created or built in the manner they envisioned. The 4 foot x 8 foot space they allowed for the pool equipment is always <i>way too small! </i>They often design pool walls that are too thin to place the required piping inside the concrete and rebar. Pool equipment placed uphill from the pool, needs to be re-located below the pool. Retaining walls without waterproofing and drainage will quickly fail from hydrostatic pressure.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Just because it's on the internet, it's not so...</b></u></span><br />
<span style="font-size: x-large;">A lot of architects and landscape architects rely on details and information that they find on the internet.</span><br />
<br />
<span style="font-size: x-large;">And a lot of information available on the internet is garbage posted by idiots. These are the "fly by the seat of their pants" types, who build and design without experience or regards to the building codes and industry standards.</span><br />
<br />
<span style="font-size: x-large;">Remember the commercial.. "Here comes my boyfriend. He's a French model I met on the internet." Only he's gangly, ugly and speaks broken french?</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;"><u><b>Pay me now, or pay me a lot more later</b></u></span><br />
<span style="font-size: x-large;">It costs a lot more to tear out portions of a failing project, than it costs to design and build them correctly in the first place.</span><br />
<span style="font-size: x-large;"><br /></span>
<span style="font-size: x-large;">Add to that added cost, the aggravation of tearing up the project, damaging good work to get at the failed portions. Throwing good money after bad. Not to mention the lawsuits and sleepless nights.</span><br />
