Changing Out The Water In Your Pool

If it’s time to change out the water in your swimming pool you will have a couple of different options. First many residential and commercial swimming pool owners will probably ask why would I have to change out the water in my swimming pool? Typically, most swimming pool owners will need to change out the water in their swimming pool for the following reasons:

  • High Calcium Hardness (CH)
  • High Total Dissolved Solids (TDS)
  • High Cyanuric Acid (CYA)
  • High Phosphates
  • High Salts
  • Presence of waterborne diseases like Cryptosporidium (Crypto)

Depending on where you live there are a variety of factors why you would need to change out the water in your swimming pool. Typically, most pool professionals will recommend it because when the above occurs it will cause calcium scaling on the water tile line, the interior finish, filtration equipment, spillways, and decorative water features. When scaling occurs it can make your backyard paradise tough to look at and it can be extremely costly to have it removed. CH in many parts of the country is present in the tap/fill water. When pool water evaporates, calcium will remain in solution and gradually build up in concentration. This will cause your TDS to rise too. Over time, as calcium scales on the interior finish and filtration equipment, it will take life off of your swimming pool and equipment.

To combat this problem and to alleviate some of the other issues that we listed above, you can either drain your swimming pool or recycle it water using our Reverse Osmosis (RO) mobile filtration equipment. If you choose to drain your swimming pool it can take up to 2-3 days to perform this process, there’s a chance you could damage the interior finish and you will be filling it up with moderately hard water again. Whereas, if you choose to recycle your swimming pool water it will leave you with drinking quality water conditions, it can be performed in less than a day and you can swim in the pool during filtration. This past week we were called out to a 46,000-gallon residential swimming pool with the following chemistry:

Initial Chemistry

Calcium Hardness – 1000 ppm (high)

Total Dissolved Solids – 5600 ppm (high)

CYA – 80 ppm (moderately high)

After filtering this swimming pool for 28 hours we were able to leave them with the following ending chemistry and conserve 85% of the existing water in the swimming pool.

Calcium Hardness – 150 ppm (better than tap water)

Total Dissolved Solids – 800 ppm

CYA – 0 ppm

Please keep in mind that this service is currently available in California, Nevada, Arizona, Oklahoma, and Texas. When comparing it to a typical drain and refill it is much better because we give you better than tap water, you will notice that the water is softer and there’s no risk of cracking the foundation of the pool because the water level never changes. If you have the option to perform RO on your pool water it is the smartest decision. If you should have any questions about how this service is performed, please contact us today!
