Pool Draining & Cleaning

One of the most challenging parts of properly maintaining a pool is handling the harsh environmental conditions of the Sonoran Desert and the hardness of our water supply. To keep your pool comfortable to swim in, looking its best, and safe, it is important to drain OR treat the water when certain water quality parameters get too high.

Cyanuric acid (CYA) builds up quickly if only chlorine tablets are used to chlorinate your pool. High CYA reduces the efficiency of the chlorine in your pool which means higher chlorine levels are needed to sanitize the pool.

In most parts of Chandler, Tempe, Ahwatukee, Gilbert, and Mesa calcium hardness out of the tap is around 200-400 parts per million (ppm). The standard for pool water is also 200-400 ppm. Due to evaporation of pure water from the pool, it is not unusual to exceed the calcium hardness standard after a single summer. High calcium makes balancing the pool water more difficult and can result in scale formation on the pool surfaces as well as scaling in the pipes, plumbing and filter. Through proper testing and water balancing, problems associated with calcium levels exceeding standards can be minimized.

AZ Oasis Pools will discuss your pool and goals with you and then recommend if treating or draining your pool is needed. In general, pools need to be drained every 2-3 years. Our goal is to prevent problems, not repair them after they occur.

After draining the pool, the interior surface can be sprayed down, scrubbed, acid washed, or chlorine washed if needed or desired.
