Stay waterwise with your pool as temperatures rise

By AMWUA Staff

As temperatures continue to rise and we prepare for the Memorial Day weekend, more people will be looking to stay cool in a pool. Before diving in, ensuring your pool runs as efficiently as possible throughout the summer heat is important. After all, outdoor water use accounts for most of a household’s monthly water budget, and pools are among the most significant outdoor water users.

A good place to start for having a water-wise pool is to check for leaks. Leaks in your pool system may be difficult to find and create water waste, leaving you with a high water bill. Often, leaks like these can go undetected for the entire summer, causing a significant amount of water loss. An ongoing pool leak can waste hundreds of gallons of water.

To ensure your pool is in tip-top shape regarding water use, here are some easy steps for you to take.

First, look for any visible leaks
Turn the pool equipment on and look for visible leaks from pipes.

Walk around your pool and yard while carefully inspecting the area around your pool equipment, where many leaks can be found.

Look for white crusty mineral deposits on pipes, which could indicate a slow leak. Also, look for wet spots on the ground around the pool, pool equipment, and between the equipment and the pool.

Test for hidden leaks
Check the pool autofill for proper operation. Pool water evaporation is normal; however, an abnormal drop in water level may indicate a leak. An autofill (automatic pool water leveler) can mask a leak as it will automatically replace lost water, thereby preventing a visible drop in pool level.

You can also do the bucket test, which is easy to do. Just follow the simple instructions below:

  1. Disable (turn off) the autofill (if present).
  2. Place a bucket or container on a pool step without submerging it.
  3. Use a large rock or brick to weigh down the container.
  4. Fill it with water so it is the same level as the pool water.
  5. Mark the water level inside the bucket using either a water-soluble marker or a piece of tape.
  6. Mark the pool water level on the outside of the bucket.
  7. Wait at least two to three days to let natural evaporation occur.
  8. Compare the two water levels.
    A. If the pool water level (outside mark) has dropped more than the bucket's water level (inside mark), you may have a leak and may want to contact a pool contractor. 
    B. If the level changes are the same, only evaporation has occurred.     
  9.  Resume normal autofill operation.

Once your leaks have been fixed, there are a few other simple ways to conserve water in your pool this summer.

Keep the filter clean to avoid backwashing.
Clean your filters regularly. The average backwash uses between 250 to 1,000 gallons of water. So remember only to backwash when necessary. Recycle your water by running your backwash water onto lawns and shrubs. Ensure water is absorbed before it leaves your property and avoid allowing runoff to enter adjacent properties.

Lower the pool temperature.
Reducing the temperature also reduces water loss from evaporation. Cooling pumps can lower pool temps up to 15 degrees.

Don’t overfill the pool.
Keep the water level lower to reduce water loss due to splashing.

Now you are properly prepped to stay cool, be waterwise, and ensure water remains in the pool where it belongs. Also, make sure you check for leaks periodically throughout the summer and year-round. It’s an easy way to conserve water and save money.
