At Pure Water Industries, we highly recommend changing out your pool water at least every two years (maybe sooner if you have a salt system)! Due to the high Calcium Hardness (CH) in many areas of the country along with high Cyanuric Acid (CYA) levels that many pools have, you should change out your pool water often. High calcium levels alone is one of the main reasons why residential and commercial swimming pool owners should replace their water every two years. Specifically, in the San Diego area, we deal with higher levels of Calcium Hardness in our tap water and it can cause major damages to your swimming pool, your filtration equipment, and your salt chlorinator as well! At Pure Water Industries, we offer an alternative to a typical drain and refill because draining a swimming pool can cause any one of the following:

  • Cracking the interior finish
  • The pool could float (more common in Central and Eastern United States)
  • The walls could collapse
  • It is a huge waste of water that can be reclaimed

Since we are located in the Southwest United States, we are extremely concerned with the water but if you have the opportunity to save the water by recycling it instead, all of the above risks go down substantially. With our Reverse Osmosis (RO) mobile filtration “Puripool Process” the water level in the swimming pool never changes and the end product is much better than tap water. The process will lower CH, Total Dissolved Solids (TDS), salts, CYA, and so much more! Not to mention, we can conserve up to 85% of the existing water in the swimming pool too!

Just last week, we were called out to an 18,000-gallon salt swimming pool in Del Mar, California because the scaling on their salt chlorinator was high.  One of the major issues with salt pools is calcium scaling, which can cause the system to malfunction when the levels get too high. The calcium scales the electrode plates which prevents the production of chlorine. When this happens, the calcium levels in the water must be lowered. This can be done with our mobile filtration Reverse Osmosis (RO) trailers. When we arrived at this 18,000-gallon swimming pool the customer’s initial chemistry was….

Calcium Hardness – 760ppm

Total Dissolved Solids – 5757ppm

Cyanuric Acid – 60ppm

After filtering this swimming pool for 12 hours we were able to lower the above issues to the following:

Calcium Hardness – 130ppm

Total Dissolved Solids – 959ppm

Cyanuric Acid – 0ppm

After filtering, the residential swimming pool owner added salt and CYA which allowed their salt chlorinator to operate correctly. Using our service is a much better option than a drain a refill because we will leave you with better water than tap. Not only will you conserve water but it can and will prolong the lifespan of your swimming pool too.
