How to Conserve Pool Water FAQ

How much water does my pool lose to evaporation?

An average pool loses about ¼ inch of water a day due to evaporation. That can really add up over time. Adding a cover and keeping your pool clean and balanced can significantly reduce any water loss. Cover Free, an invisible liquid barrier, can help reduce evaporation when your pool is in use.

How will keeping my pool clean and balanced save water?

A cleaner pool needs less chemicals and backwashing. Keeping your pool covered when not in use both reduces evaporation and can help keep debris from blowing in your pool. Pools don’t often need draining if chemical levels are properly maintained. Test your water weekly or bring a sample in for a free water test at any Leslie’s location.

Is it true that a pool or spa uses less water than a lawn?

That’s correct! If you keep your pool maintained it will use less water per day than an irrigated lawn. The pool and deck area further takes away from landscape that requires water use.
For example, a 1,200 sq. ft. pool requires 30,000 less gallons of water than a lawn the same size.

How can I check my pool and equipment for leaks?

If you’re adding more than two inches of water to your pool weekly, you may have a leak. Inspect your equipment pad – take a close look at the filter, pump, heater and pipe valves for any visible leaks. Check the ground around your equipment pad and pool for wet soil and sunken or eroding areas. Mark your water level with tape or a grease pen and keep an eye on the level. Water loss out of the ordinary can signal a leak you may not be able to see.

How can I minimize backwashing?

Most people backwash more often than they need to. Each time you backwash you use between 250 to 1,000 gallons of water depending on your pool and equipment size. When backwashing your filter, keep an eye on color and quality of the water and stop the backwash process as soon as you can. Keep a cover on your pool when not in use to minimize debris from finding its way into your pool. Remember, a cleaner pool means a cleaner filter and less backwashing.

Switching to a cartridge filter can also eliminate the need to backwash completely.

What is the benefit of a cartridge filter?

The amount of water saved is the number one reason to use a cartridge filter. Instead of backwashing, cartridge filters only need to be removed and hosed off. Cartridge filters can actually trap smaller dirt particles than a traditional sand filter. They also work great with lower pump pressure which can reduce your energy cost!

I already have a cover and checked for leaks, what else can I do to help?

To help reduce evaporation, add water to your pool during the early morning or evening instead of mid-day when the sun is out. If your automatic pool cleaner has a tile-spray option, be sure to turn it off to avoid additional water loss. A large amount of the spray evaporates before it even reaches the tile! Try running your pump only when needed or upgrade to a Variable Speed Pump to save water and energy. Consider using your backwashing water to irrigate your salt-tolerant plants. Every small step adds up to big water savings!

Rebates are often available for upgrading to a more efficient VS Pump or adding a solar cover to your pool. Check with your water and power provider to see what rebates are available in your service area.

Some simple tips to conserve water and stay cool this summer:

  • Use a solar cover. It can decrease evaporation by up to 95%, and make your pool as efficient as drought resistant landscaping.
  • Minimize splashes in the pool by lowering the water level to 1 inch above the bottom tile. Also turn off any fountains or waterfalls.
  • Check your filter and keep it clean. Consider replacing sand and DE filters with cartridge filters, which don’t need backwashing.
  • Keep the temperature down. Keeping the pool temperature down will reduce evaporation.
  • Balance is key. Properly maintain your pool or spa to avoid backwashing and extend the water life. Run your pump only as long as needed.
