There are many dangers of draining a swimming pool! As a residential swimming pool owner in Las Vegas don’t be surprised to hear that it’s time to drain your swimming pool. Due to our extremely hard water that is loaded with calcium and other hardness minerals pool professionals will recommend changing out the water in your swimming pool from time to time. With rising Calcium Hardness (CH), Total Dissolved Solids (TDS), and Cyanuric Acid (CYA) levels in your pool these are primarily the major reasons why someone would recommend changing out the water in your pool. Please keep in mind, our tap/fill water is hard and there is nothing you can do to prevent these factors from happening. But, as a residential swimming pool owner, you should be proactive in changing out the water in your swimming pool every two years and we hope this blog post explains why!

As we stated above, our fill water is loaded with calcium and other hardness minerals. As pool water evaporates those hardness minerals remain in solution and build up in concentration. When this happens it will scale your water tile line, interior finish, salt chlorinator, filtration equipment, spillways and decorative water features! This scaling can be extremely hard to look at and extremely expensive to remove. Since our water is hard in Las Vegas you are going to need to be proactive and change out the water every two years to prevent this from happening. So you must change out the water every two years but we want to explain why draining a swimming pool is so dangerous.

  • In-ground vinyl liner swimming pools are the most dangerous to drain because the older pools may not have been built structurally to hold back the weight of the dirt against it when the pool is drained. When the pool is drained it can cause the walls to collapse or groundwater can cause the liner to float; neither of which are good for swimming pools!
  • In-ground concrete pools are built structurally 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 will not go back down!
  • In-ground concrete swimming pools can also crack when the temperature is above 70-75 degrees and the surface of the swimming pool doesn’t remain wet.

That’s why when it is time to change out the water in your swimming pool, we recommend calling us and using our Reverse Osmosis (RO) mobile filtration trailer to lower CH, TDS, and CYA. This process conserves up to 85% of the existing water in the swimming pool and since the interior finish isn’t exposed there’s no risk of cracking the foundation.
