If you think you have a leak in your pool, there is an easy way to determine, for yourself, if your pool is losing water from a leak or simply from evaporation
Bring the pool water up to its normal level
Turn off the auto-fill
Fill the bucket over halfway with water
Place the bucket In the pool. It is best to place it on the second step if possible
Mark the bucket water level on the inside of the bucket with a marker
Turn off the pool's pumps
Mark the pool water level on the outside of the bucket with a marker
Begin the pool pumps
After 24 hours, compare the level of water in the pool with the water level in the bucket. If the water-level In the pool has dropped more than the water level in the bucket, you probably have a leak and need to call United Leak Detection at 888-422- LEAK.
**NOTE: If you have a Spa and Pool combo we recommend that you isolate the Spa if possible
