The easiest way is to perform the bucket test. Fill a bucket with pool water, set it on a pool step, and mark the water levels on both the bucket and the pool wall. After 24 hours, compare the two. If the pool’s water level drops more than the bucket’s, you likely have a leak. Evaporation will affect both equally, while leaks will only affect the pool. We recommend that you turn off water features during this test.
