24 hour Water Loss Test

All pools lose some water due to evaporation. The trick is to find out if the drop in pool water level is due to a pool leak or just normal evaporation.

Follow the instructions below to determine if your water loss is a leak in the pool or normal evaporation.

  1. Place a nearly filled  bucket of water on the first or second step of your pool.
  2. With a pencil, mark the water level in the bucket.
  3. Turn off the pool pump and let the water settle.
  4. Mark the pool water level somewhere on the outside of the bucket.
  5. After 24 hours, measure the space between each mark and the new water level.

Pool Leak? Or Normal Evaporation?

General rule of thumb is that most pools will lose around 1/8 of an inch per day due to normal evaporation. Pools in breezy locations may lose more.

If your pool is losing a 1/4 inch more than the bucket in a 24 hour period, it’s very likely that your pool may have a leak.
