Dangers of Draining A Swimming Pool

If you own a residential or commercial swimming pool in many areas of the country it is recommended to drain and refill your swimming pool every couple of years. If you live in warmer climates most pool professionals will recommend a water change when your Calcium Hardness, Total Dissolved Solids (TDS), and Cyanuric Acid (CYA) levels get above what is the recommended range. Some will also recommend it if you have the presence of a waterborne disease like cryptosporidium. Even though draining and refilling a swimming pool is commonplace there are many risks involved and we want to educate you on those as well as an alternative to a drain and refill. The following are the most common risks:

  • In-ground vinyl 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 you drain this type of swimming pool, it can cause the walls to collapse, or groundwater can cause the liner to float; neither of which are good for swimming pools!
  • 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 groundwater is high enough, it can actually push the entire pool out of the ground.  Once a pool has popped out of the ground it can’t 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 underwater) and contracts when the water is taken away.  Once this finish rehydrates, it expands and the risk of delamination occurs.

Recycling your Pool Water is a Better Solution

Do you think it’s worth the risk of potentially causing thousands of dollars of damage to your swimming pool when you can save the water and swim in drinking quality water? At Pure Water Industries, we offer an alternative to a drain and refill. It’s called the Puripool Process. This service uses Reverse Osmosis filtration to lower calcium, TDS, CYA, and so much more without draining the swimming pool. The Puripool Process comes to your residential or commercial swimming pool and recycles the water onsite. In the end, we give you better water than tap and since the interior finish of the pool is never exposed, there are no risks involved.
