24 hour Water Leak Test

All pools lose some water due to evaporation. The challenge is to find out if the drop in the 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 almost full (within a half an inch of the top) bucket of water on the first or second step of your pool.
  2. With a pencil or piece of tape, mark the water level in the bucket.
  3. Turn off the pool pump and let the water settle.
  4. Remove the skimmer lid and make a short pencil line at the current water level somewhere on the plastic skimmer body.
  5. After 24 hours, find the drop in water level by measuring the space between each mark and the new water level.

Pool Leak? Or Normal Evaporation?

If the water drop in the bucket and pool is the same or very close, you likely do not have a pool leak. 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. Heated water and the measure of relative humidity will also have an effect on pool water evaporation levels.

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.
