Frequently Asked Questions

Cost Questions

What is the cost for your service?

We price our service based on the size (volume) of your pool.  Most pools should fit into the two categories.  If yours is larger, please contact us for a quote.

up to 25,000 gallons: $650

up to 30,000 gallons $750

For pools in Orange County, we offer a third price category for smaller pools:

up to 15,000 gallons in Orange County $550


General Questions

What problems can occur with hard water?

Pool equipment (heaters and pumps) will not honor the equipment warranty if your water has too high of calcium content.  Many manufacturers consider just 400 ppm (parts per million) as too high.  Most tap water in Southern California is well over 200 ppm.  The water in the pool will eventually evaporate- leaving behind the calcium.  Every time you refill your pool water, you are just adding more calcium.

How bad can calcium really be?  Limestone- a sedimentary rock is made of calcium.  Hard water is really just a measure of how much calcium is disolved in your water.  This is a very hard mineral deposit and it can-and does-affect your pool equipment. Once this Calcium Carbonate builds up in the heat exchanger, the heater cannot efficiently heat the water, and it takes longer and consumes more gas than it should. Over time, the heat exchanger will fail and the heater becomes useless. New heaters are very expensive!

A Calcium buildup in your pool pump will eventually cause your pump to fail as well. Did you know that swimming pool pump manufacturers do not warranty pumps (or heaters, for that matter) that have failed due to hard water deposits? Pumps, while not to the extent of heaters, are also very expensive to replace.

Does your plaster look like it has a disease? That is scale or hard water build up, and it is not only unsightly, but also detrimental to the plaster itself. Calcium builds on itself and blotchy “stains” appear. Some may even look like small stalagmites growing up and out of your pool floor and walls (which is exactly what they are) This scale can also deposit itself in your pool plumbing lines and inside your filter.

Why would I need your service?

You may not be able to see it in the water, but you can see the effects in other areas.  Calcium deposits form on the waterline tile and on the pool surface itself.  Do you have weird, white growths on your pool walls and bottom?  They are probably calcium deposits.  Calcium is the ingredient that makes limestone, and although it is not the hardest rock around, it is still a rock that forms from calcium deposits.  This is why pool equipment manufacturers will often void their warranty if your pool water contains over 400 ppm (parts per million) of calcium.

Are there chemicals that I could use to address this water hardness?

While there are products that will hold the hardness minerals in suspension, they will not lower the level of hardness. This is a short term approach and a costly one as well, as you are not only paying for these chemicals, but are also changing the chemistry of the water and requiring higher sanitizer levels to maintain a clean, safe pool; you are only prolonging the inevitable! The only true way to bring your Calcium Hardness to ideal levels is to filter your water and bring the levels down to the acceptable range. This means lowering your Calcium Hardness closer to the 200 PPM range, which is the low end of the ideal range.

How is hard water typically addressed?

In the past, the water was dumped down the drain! If the average pool has 20,000 gallons of water and if only 1,000 pool owners (out of the tens of thousands in our area!) dump their water a year, that means 20,000,000 gallons of water is wasted!

Why is my pool water “hard” and why does it get “harder”?

From the day your pool is first filled, it is often above the standards for pool water chemistry in Calcium Hardness (200 to 400 parts per million, or ppm) and continues to increase as you remove water by getting out of the pool, splashing or evaporation. To replenish this lost water, new water is added and additional hard water is introduced; raising the concentration levels of this hard water (predominantly Calcium and Magnesium) and creating a higher level of these minerals. This level increases, creating such hard water that your chemicals can no longer do their job, dictating the need for higher chemical levels to keep the pool safe. Additionally, scale builds on your interior finish, tile, pool plumbing and equipment, which can lead to failure and expensive repairs!

Process Specific Questions

What are the steps of the process?

The trailer has a touchscreen control that also has a webserver built in. We can login and see the TDS level of the water coming into the trailer and out, the pressure of the water arriving at the 10micron prefilter and coming out of it, and the pressure into and out of the RO membranes.  We can start and stop the system, and speed up or slow down the pumps.

  1. Water from the pool is pulled in through the suction line to the trailer where it first encounters the
  2. UV purification system. This kills off harmful bacteria that might be present in the water.  Then the water moves on to the
  3. Pre-filter bag that keeps dirt and other larger suspended solids from going through the Reverse Osmosis membranes.
  4. The water then goes through a large motor that pressurizes the water to 200 psi for the Reverse Osmosis (RO) membranes.
  5. The water is squeezed through the RO membranes.  This is the step that removes the dissolved solids.
  6. The purified water that makes it through the membranes is returned to the pool immediately. The impurities that were rejected by the membranes are sent down the sewer.
  7. The water that is sent down the sewer is replaced with a standard hose connection to the trailer, or through auto fill if the pool is so equipped.
How long will it take to process my pool?

Currently we are able to treat 40,000 gallons a day, to drinking water levels! Obviously the size of your pool is the deciding factor on how long it will take based on this level. However, most pools will take between 8 and 10 hours to complete.

Is the process safe?

It would be just as fair to ask if it is safe to take a bath or a shower in tap water!  The only thing that we are doing is taking what is essentially dirty water and returning better than drinking water. There are no power cords or electricity in or near your pool.  An inch and a half hose with a Virginia Graeme Baker Act (VGBA) compliant fitting is placed in one end of the pool to draw the water back to the trailer for treatment and another inch and a half hose returns the clean (drinkable!) water back to your pool. That’s it! We are 100% self-contained.  Recently a university pool not only stayed open during our process, but they hosted several intercollegiate water polo matches!  All we need from you is a fresh water supply to replenish the small amount of water, approximately 15%, that is lost during the process.
