Service Guide

This guide is created to answer the questions most often asked by our customers.


A service record will be kept inside your time clock which documents the date and time of our service technicians most recent visit.  Swimming should be delayed for a period of one hour after chemicals have been added to your pool.  This is a standard recommendation for most forms of pool chemicals.



Pool Covers: Your pool cover should be pulled off on service day.  Our service techs are instructed to leave the pool uncovered upon completion of service.  The cover should remain pulled back for at least three hours after service. We recommend that your pool be uncovered at least 50% of the time.  A pool that is covered all of the time lacks adequate oxygen which can cause chemicals to react abnormally and result in the pool's water chemistry being out of balance and /or eye irritation.  Frequent removal also helps to prolong the life of your cover.


Water Balance:

Our chemical readings are the same if not identical to those obtained when conventional chemicals are used.  We strive for the following readings:


   pH: 7.2 - 7.4

   Alkalinity: 90 - 130 PPM

   Chlorine: 3.0 - 4.0 PPM

   Conditioner: 100 PPM


These readings, when achieved in conjunction with the use of our chemicals, are both safe and ideal for your pool and equipment. 

You may feel confident knowing that our 30 plus years of experience have proven these readings to be the best and safest for you and your pool.



Please provide easy access for our service  tech.  If  you keep your gate locked, please provide the service tech with a key.   Unfriendly dogs should  be secured when the pool is being serviced.  If a key is not provided and the gate is inadvertently locked on service day, or an unfriendly dog is loose in your backyard, it will be necessary for us to charge for the service not performed and no extra call-back will be made.  Because our low service charge is based on promptness and efficiency, we do not ring doorbells to gain access.  Also, it is very important for safety reasons that no one but the service tech be in the yard while the pool is being serviced.


Cleaning: We do not brush or vacuum the pool as part of our service.



We take every precaution to keep your dog in your backyard.  However, if your dog attempts to get out when you open your gate, he probably will do the same with us.  We therefore cannot assume responsibility for your dog getting out.  Our service tech will not enter your yard if you have an unfriendly dog that is not contained and it will be necessary for us to charge for that service call.


Spas and Hot Tubs:

Our service does not include spas or hot tubs.  If the plumbing of your pool is connected to your spa, the chemicals will automatically circulate into the spa.



If your pool has algae we will work to clear it up.  Because some types of algae are more resistant than others, please allow a reasonable period to completely eradicate it.   Black algae must be brushed often with a stainless steel wire brush.  It will turn gray as it starts to die and will eventually disappear.  Keeping the pool clean and properly filtered will aid in the treatment of algae. PLEASE DO NOT ADD ANY CHEMICALS OR ALGAECIDE TO YOUR POOL as this can cause inaccurate test results and lead to other problems.  We do not store any chemicals at the pool site.  Our service tech will complete all necessary testing and add any required chemicals during each weekly service visit.


Filter and Filtration:

ADEQUATE FILTRATION IS AS IMPORTANT AS GOOD WATER CHEMISTRYWith the dramatic increase in energy costs, some people try to economize by reducing the filtration time of their pool. This often counteracts our efforts to  keep your pool sparkling clean.    We will provide the proper water treatment but you must see to it that your pool is properly filtered.  It should be noted that our service does not include cleaning or otherwise maintaining the pool filter.  Our office will provide a referral for these services, upon request.. It is important that each and every drop of your pool's water is pumped through the filter three times each day to assure that it has been properly and adequately filtered.  To accomplish complete filtration of the water we recommend the following:


              Sand Filter 10-12 Hours

              Cartridge 9-10 Hours

              D.E. 8-10 Hours


Increase the time by 50% if you have a solar heating system.  Allow longer filtration periods if the pool activity is heavy. Our personnel will advise you, by means of a door hanger on your front door, if your pool requires more filtration.  It is in your pool's best interest to follow the recommended filtration time.  Filters should be cleaned when the pressure, indicated by the  pressure gauge on the top of the filter, rises 7-10lbs. above the clean pressure.




The most common cause of cloudy water is inadequate filtration.  Increase the filtration time and the problem should resolve itself (see Filter and Filtration).  If it does not, you may have a malfunction in your filtration system.  We recommend contacting your repair company for repairs.


Eye Irritation: 

You may have heard that chlorine causes eye irritation.  This is simply not true.  The fact of the matter is the eye irritation is caused by:


        In adequate filtration (most frequent cause)

        Ammonia introduced into the pool water by means of urine. (One small child urinating in your pool can cause very heavy eye irritation for up to 24hrs.)

        Organic material introduced into your pool by adding fresh water before swimming. (Always add water AFTER you swim - (NEVER BEFORE)

        Leaving a pool blanket on your pool during the day. Water needs to be exposed to air.  Please remove the blanket during daytime hours.

        Perspiration in pool -- always shower before swimming.


Conditioning: On our first visit, the service tech will perform numerous tests on your pool water, including a test of Isocyanuric Acid, commonly called Conditioner.  Conditioner screens out ultraviolet rays and prevents the sun from taking chlorine from your pool water.  Without it, sunlight will take the chlorine almost as fast as we can put it in.  Once added, it stays permanently as part of your pool water and does not evaporate or dissipate.  It only disappears when water is lost through emptying your pool, plumbing/pool leakage, excessive splash out, heavy rain, water overflow, etc.  If, on our first visit, we find that the conditioner level is below 100 parts per million, we will add only enough conditioner to bring your pool to 100 PPM.  The first twenty pounds of conditioner required each calendar year are free to our customers.  If any more is needed to obtain or maintain the 100 PPM, the cost is passed on to you at the current wholesale rate.  The most an average size pool would take is approximately 15+ pounds a year.


Chlorine and Stains: There are many sources that contribute to the accumulation of metals or minerals  in swimming pool water.  These often cause "staining" of the pool surface.  It is not possible to guarantee that staining will not occur in a pool or that the simple addition of chlorine will not cause the settling of metals from the water once it becomes saturated with metals.  Scaling, stains, discoloration and cloudiness in a pool are caused by the settling out (precipitation) of metals in the water.  If the precipitated metals form a hard deposit on the pool walls it is referred as scaling.  If the precipitated metals have a color and are deposited on the pool walls, they are called stains.  Superchlorination is essential to proper swimming pool maintenance.  When superchlorination is done with any form of chlorine (i.e. gas chlorine, sodium hypochlorite, calcium hypochlorite, sodium dichloroisocyanurate, and trichloroisocyanuric acid), there may be an immediate settling out or precipitation of metals from the water and subsequent staining of the pool.  Chlorine or acid in and of themselves cannot cause stains.  Chlorine bleaches and acid are used to remove stains from pool finishes.  Therefore, even though staining may seem to be caused by the chemicals themselves, this is not possible.  In other words, iron stains can only be caused if iron exists in the water.  Copper stains, only when copper is in the water, and so on.  Lack of filtration may cause stains to appear sooner.  The pool water needs to be circulated the recommended time for the type of filter.  Otherwise, the precipitation of the metals on the plaster is accelerated.  We highly recommend the use of Sequestering agents to help minimize this phenomenon.  It is not included as part of our regular service program but can be added.  Please call the office for details. 


Colored Plaster Pools:

The swimming pool industry is fully aware that all colored plaster pools become mottled and blotched sooner or later.  Quite often a light colored ring will appear around the main drain or the plaster will appear uneven in color.  This condition is typical of all colored plasters and is simply the nature of colored plaster pools. There is nothing that can be done from a service point of view to prevent or cure the blotching, streaking, or mottling that will occur.  Blotching may be gradual or appear seemingly overnight even after the pool is several years old.  All pool builders or plaster companies require their customers to acknowledge that blotching is a normal occurrence in colored plaster pools.
