It can be quite dangerous to drain your swimming pool. Many of you might wonder why you would need to do this and the goal of this blog post is to explain why. As residents in the Greater Phoenix area, we have hard water. Yes, our fill water is loaded with calcium and other hardness minerals. For swimming pools, it’s recommended to have your calcium between 200-400 parts per million (ppm) and in most places around the valley our water is 400ppm and higher. Not to mention, when your water evaporates the hardness minerals remain in solution and gradually build up in concentration. When this happens, calcium will scale your water tile line, the interior finish, filtration equipment, spillways and decorative water features. Do you have this problem? Has anyone told you that your calcium hardness, total dissolved solids (TDS), or cyanuric acid (CYA) levels are high and that you need to drain your swimming pool? If so, then you’re going to definitely want to read on…..

At Monarch Pool Service, we offer Reverse Osmosis (RO) Mobile Filtration which is a great alternative to a typical drain and refill. With this option, you can conserve the existing water in your swimming pool and take your hardness down to levels far below tap water. This is a great option because as of now it’s too hot to drain your pool. It’s dangerous because any one of the following can happen:

  • Vinyl in-ground liner swimming pools are the most dangerous to drain as they do not have any physical structure to hold back the weight of the dirt when the pool is drained. When the pool is drained, it can cause the walls to collapse, or ground water can cause the liner to actually float.
  • Fiberglass pools are often inserted into an excavated area and then backfilled with dirt.  Since the water weight is far greater than the weight of the fiberglass shell, removing the water weight in a fiberglass pool is extremely dangerous as it applies to these types of pools coming out of the ground.
  • In ground concrete pools are structurally built to withstand the weight of the water pushing outward on the shell, and that water weight helps keep the shell in the ground. However, if the ground water is high enough, it can actually push the entire pool out of the ground.  Once a pool has popped out of the ground it will not go back down!
  • In ground concrete swimming pool finishes (plaster) can also crack when the temperature is above 70-75 degrees and the surface of the swimming pool doesn’t remain wet.  Swimming pool plaster has been wet since the day it was installed (it cures under water) and contracts when the water is taken away.  Once this finish rehydrates, it expands and the risk of delamination occurs.

The most common swimming pool is the in-ground concrete swimming pool (plaster) and draining it in now could cause damage that can be quite pricey to fix. It’s not worth the risk especially when you have a much better option. The following are benefits which should persuade you to use our service…

  • Process takes less than a day for most residential swimming pools
  • Process can be used in commercial applications
  • You can swim in the pool during filtration (no downtime)
  • Since the water level never changes, you eliminate all dangerous aspects of draining a pool
  • The water going back into the pool is drinkable
  • Since the water is so much better than tap, say goodbye to dry skin as well as itchy/burning eyes
  • If service is used regularly (every two years) It will prolong the lifespan of your investment
