Consumer Mistakes when Buying a Swimming Pool

Many consumers approach construction projects like they are buying a consumer commodity.... which is the furthest from the truth.
 
You're not buying a TV at Walmart

A swimming pool is a personal item - one that should be designed around the buyer, their lifestyle, how they entertain and the intricacies of the building site.  Unlike consumer commodities like tv's, the quality, design and performance varies by the designer or contractor.  In construction, it is the buried components that determine the long term performance of your project - and the cost of operation.

Not getting educated

Picking companies from the Internet or yellow pages based upon a pretty website or large ad is absolutely wrong.  Most pool construction companies employ a team of salesmen, who's job it is to "sell you a pool."  They are not interested in educating you as to the correct way to build a pool.

They are only interested in signing that contract.

Do your research BEFORE you talk to the first company.  The Internet is full of information, but don't believe everything on the Internet.  Create a list of criteria that you'll use to select your contractor.

Over reaching

It is foolish to call swimming pool contractors and request a "free quote."  You cannot make rational comparisons between different designs and specifications.  Since most swimming pools are built utilizing the lowest quality workmanship & materials without any written criteria or construction specifications, how can you possibly compare bids?

Since the salesman is out to SELL you a pool he is interested in "churning out" a plan or project scheme as fast as possible.  The quality of the design and project specifications are going to be reflect in the "FREE" effort they expended!  You get what you pay for!

Lack of Due Diligence

Everyone is willing to provide you with a list of references.  They are NEVER going to give you the list of people that they pissed off.  But how do you find these people???  Through due diligence and legwork.

Check the local Better Business Bureau.  They will not be able to give you references, but their records may represent a trend.  Where there is smoke there is fire.

Check the local court records.  Many are available for review on-line.  The builder may have been a plaintiff (suing to get paid) or a defendant (sued by an upset customer).  Contact the other party, learn what went wrong, why there was a dispute, why it ended up in court, and if the issues were resolved.  TAKE THE COMMENTS WITH A GRAIN OF SALT.  Remember, you cannot always please everyone.  Some consumers are unreasonable.  What you are looking for is a PATTERN of upset consumers in their wake.

Check the Contractors Licensing Board - Not every state requires that contractors be licensed.  Those that do, usually have records visible on-line.  Search other licensed states, as some builders that had licenses revoked in other states merely move to another state.  If a contractor has had any complaints or actions against their license - again, it illustrates that they cannot resolve issues before they get out of hand.

Check out on-line reference websites: The Franklin Report, Yelp, Angie's List and others.  Again, take what you read with a grain of salt.  Remember, you are looking for a pattern of happy or unhappy customers.

Review building permits issued in surrounding communities.  Most building departments have searchable on-line databases.  Search for the last 4-5 years of permits.  Contact these owners.  Most will be happy to provide a candid review of the contractor.

Price Point Decision Making

Warning: The prices are going to be all over the map.  Trying to compare apples, to oranges, to grapes, to lemons will only result in a brain full of fruit salad.  How do you make sense of it all?

It is best to obtain a design package (sometimes called a "bid package").  The entire project will be defined with schematics of the plumbing, high & low voltage electrical and lighting.  It will include illustrations of the minute details that are unique to your project.  It will also include construction and workmanship specifications.

Utilizing a "bid package" allows all possible contenders to provide a quote based upon the same exact set of criteria.  Stand your ground - ensure that they realize that substitutions are NOT ALLOWED.  This will ensure that the design does not get altered and that the performance is not degraded.  It also ensures that you are comparing APPLES TO APPLES !

REMEMBER: 
YOU GET WHAT YOU PAY FOR!  
IF SOMETHING IS TOO GOOD TO BE TRUE - IT IS!


On-line Quotation or Consulting Services

You cannot design a pool or provide a quotation on-line.  Just like I cannot paint your house or change your car's oil over the phone.

It is impossible for anyone to validate any assumptions that they make over wires.  They must visit your site, sit down with you, understand your budget and needs.  They have to get to know YOU!

Prices are lower in a down economy or in the off season

 Labor expenses, overhead, insurances, fuel, concrete, steel and everything else that goes into the construction of a pool is constantly increasing in price.  

There is no better time than RIGHT NOW to build a pool.  Why?  Because next year those items are going to cost even more!

The best pool designers and contractors are still busy, even in a down economy.  They are not going to "work for wages."  It ends up becoming a losing proposition in the long run, and the smart ones know that.  And you don't want to hire the dumb ones that will work for wages.  They just won't have the resources to perform system tweaks later on or perform warranty repairs.

Failing to Review and Understand the Contracts

A contract is a two-way street.  It should clearly define everything that you are to receive.  It should outline the contractor's obligations.  Anything that was promised during a sales presentation should be included in writing.

Ensure that a dispute resolution process is included.  Know what your obligations are: paying invoices within XX days of receipt; providing a soils/geotechnical report; marking property lines, boundaries and easements; obtaining planning department or HOA approval; providing trash disposal, dumpsters, electricity or toilet facilities; repairing fences, sprinklers, sidewalks and driveways, upgrading the electrical or gas meter... the list goes on and on.

Not obtaining proper structural or mechanical designs

Most swimming pools are design and specified by the salesman.  They have little or no knowledge of structural engineering, proper filtration, circulation or hydraulic designs, mechanical systems, water chemistry management, state of the art controls and automation or alternative energies.

Most select plumbing sized based upon a guess and not sound hydraulic design calculations.  When properly sized, the response from most potential bidders is "the pipes are way too big," "who specified these huge pipes?," "way overkill."  In reality the plumbing should be specified based upon the science of hydraulics (physics), which these contractors and salesmen apparently do not understand.  When you hear these responses, you should have one reaction... cross them off of your list.

Do they require a soils report?
Where do they obtain their structural engineering?  
Does the structural engineer actually review YOUR project plans, site/topographical map AND the soils report, prior to defining the strength of the pool shell and placement of the steel?  
 Will the engineer sign on the plans that they have reviewed those documents?  

This is very important because:
a) it ensures the consumer that the contractor forwarded those documents for review
b) you'll know that the document were actually read by the engineer
c) many contractors just buy random structural engineering on-line or mail-order (based on their best guess)
d) you are guaranteed that your pool is going to be built to withstand the forces from your soil and your site conditions.

Thorough plans prevent surprises

Having a thoroughly thought out set of plans with defined specifications ensures that there are not future surprises.

The plans should also include any infrastructure required for future projects.  Getting water, gas, sewer & electrical routed under the hardscapes & plantings now, will be less expensive than tearing it all up to install them at a later time when that outdoor kitchen, shower, cabana, guesthouse, garage or barn is built.  Maybe incorporating future connections for alternative energies may be something of interest. 

The safety components of the project, from fencing & gates, door alarms, pool covers or an integrated anti-drowning alarm system should be a part of the plans and contract.  You don't want to miss the final inspection because those items were left off for you to handle.

Best Advice

1) Hire a well respected designer or consultant to design your dream backyard, before you start construction.  
2) Hire the best contractor that you can afford.  
3) And if you are not hiring the BEST AVAILABLE, then come to the realization NOW that everything will not be PERFECT.  Nor should you expect or demand perfection from those lesser contractors.

Chlorine: Burning eyes, itchy skin, respiratory distress - Falicies

Simple and plain truth - it is not the CHLORINE that is causing the burning eyes, itchy skin or the "smell of chlorine" around the pool !  What you are experiencing are the negative effects of waste products that accumulate in the pool when there is NOT ENOUGH CHLORINE PRESENT to destroy them.
Skin rashes, respiratory ailments & burning eyes

The facts are plain & simple: it is not the chlorine that causes bather discomfort. It is almost always from other water chemistry issues, and almost always due to the lack of proper chemical maintenance, testing, and the incorrect dosing of chemicals.

Among the most common complaints:
itchy skin (too little chlorine)
burning eyes (bad pH or too little chlorine - ammonia compounds)
green hair (excess copper)

All of these are attributed to other factors... but ignorant people immediately point their finger at the chlorine - because they "smell" what to them must be chlorine.  In actuality, the ammonia compounds and gasses that are formed when chlorine combines with bather waste SMELL like chlorine bleach.

And because people smell a strong "chlorine" odor around a commercial or indoor pool, or worse yet, a health club spa - they immediately (and incorrectly) assume that there is too much chlorine in the pool!

What you are really smelling is actually resulting from the LACK OF CHLORINE! You are smelling the the ammonia compounds, called: chloramines, off gassing.  When there is a sufficient quantity of chlorine in the water chloramines cannot form.  When the bather load exceeds the quantity or feed rate of the chlorine, chloramines begin to form.

This is why you "smell chlorine" on your skin after swimming - but in reality, you are actually smelling your perspiration that has combined with the pool's chlorine that formed chloramines (ammonia compounds) on your skin!  A simple shower with soap and water will remove them.

THERE IS NO SUCH THING AS A CHLORINE FREE POOL

Because of the public's confusion about chlorine and the negative side effects (incorrectly attributed to chlorine), equipment manufacturers started touting "chemical free" pools.  People suddenly all wanted a "SALT WATER POOL," because they are chemical free. 

NEWS FLASH: These are not chemical free!  Instead they are MANUFACTURING CHLORINE from the salt in the water!  Just because you are not dumping powdered or liquid chlorine into your pool, does  not mean that it is not there!  Ha, ha - they fooled you!

As "Chlorine Free" as you'll ever get
The only real "new"technology is ozone (though it has been around for 30+ years). Done properly with sufficient contact time before re-entering the pool or spa - it has awesome effects on the water quality. Ozone works synergistically with the chlorine, taking over the business of oxidizing bather waste. Since ozone is a thousands times better oxidizer than halogens (such as chlorine, bromine, hydrogen peroxide), it takes over those responsibilities, allowing the halogens to work as sanitizers. The ozone will also kill biological pathogens & viruses, which ionizers will not.

Chlorine is Safe
THERE IS ABSOLUTELY NOTHING WRONG WITH USING LIQUID CHLORINE. To be politically correct & environmentally sensitive, we call it "bleach." Chlorine has been used as a pool sanitizer for over 100+ years. It is used to treat drinking water in almost every city in the world. It is used in almost every commercial swimming pool in the world to maintain clear, safe, and sanitary water.

People who do not understand how chlorine reacts with contaminants, heavy metals, and other chemicals, continue to spread myths about what chlorine does & does not do.
For example:
Chlorine does not turn hair green, but copper does (blue staining from copper + yellow (blonde) hair = green).
You cannot smell it around a pool, even at 3-5X the normal dosages, but you can smell chloramines (which are the result of too little chlorine).
At the correct levels (1-3 ppm) it does not burn the eyes, but incorrect pH or chloramines will!
When water containing chlorine must be dumped into a storm drain or sanitary sewer, the chlorine can be neutralized - heavy metals from ionizers cannot!

People who claim that they are "allergic" to chlorine, in almost every case are really experiencing reactions to the chloramines - which can cause itching & rashes.

Someone experiencing "allergic reactions to chlorine" (actually the ammonia compounds/chloramines), could additionally be experiencing an allergic reaction(s) to any of the countless biological contaminants that accumulate in a pool (or worse yet, a spa) when the chlorine levels drop too low:
  • Molluscipox virus.
  • Mycobacterium spp.
  • Verrucas.
  • Staphylococius aureus.
  • Cryptosporidium.
  • Leptospira interrogans.
  • Trichophyton spp.
  • E. Coli
  • Pseudonomas
  • Human pathogens: blood, saliva, feces, urine, perspiration, mucus
  • Epidmerophyton.
  • Acanthamoeba spp.
  • Human papilloma virus.
  • Legionella pneumophila
In asthmatics the inhalation of chloramines can aggravate asthmatic symptoms. But because chlormaines "smell like chlorine," patients report that the chlorine caused the asthmatic attack.  Their doctor, not knowing about chloramines, reinforces the myth, and the MYTH GROWS.

Carcinogen
Additionally, alternative treatment manufacturer's and environmentalists point to the fact that chlorine is a carcinogen. Yes it is, but if the studies are investigated, one will note that the prolonged exposure, dosage quantities, and chemical concentrations of chlorine are way beyond what any normal human being will ever ingest over many lifetimes.

Again, it is the "chicken little syndrome" - "the sky is falling, the sky is falling..." Did you know that ingesting too much water, too quickly, can kill you??? Does that mean that we should outlaw the drinking of water??? Of course not, but in moderation, the exposure is more than acceptable.

The Secret is Even & Consistent Micro-Dosing
Depending on the scope of the project & chlorine needs, we use barrels to store liquid bleach that is delivered. Where large quantities are needed, say for example on Olympic sized swimming pools, we'll install an on-site electrolytic production. The electrolytic production also creates sodium hydroxide, which is collected for use in buffering the pH.

On site production doesn't always generate enough sodium hydroxide, so pH buffering is augmented with either C02 gas (it forms carbonic acid when injected to the pool water) or a 4:1 muriatic acid solution (4 parts water:1 part acid). At this ratio, the "boiling point" (vapor point) of the acid is reduced, so that caustic fumes are not generated. As an added precaution, the chlorine & acid barrel bung openings are kept sealed & barrels are vented to the outdoors with a 1/4" vent tube.

For water chemistry management and to provide an automatic & instantaneous responses to the demands for additional (or fewer) chemicals (due to 30 kids in the pool, a 100ºF+ heat spell, or a cool weather front), my preference is an automatic ORP/pH controller (CAT Controllers & Acutrol are my 2 brands of preference). It monitors the water, responding to the additional demands placed upon the pool by the environment or bathers, by controlling 2 fixed rate peristaltic pumps (Stenner is my brand of preference)- delivering chlorine & the 4:1 acid solution. 


A water chemistry monitoring system coupled with slightly over-sized ozone system, will provide you with as close to a chemical free pool as is humanly possible.
