Here is a sure fire way to test if your pool is leaking using nothing more than a five-gallon bucket and a roll of masking tape or marker.
NOTE: The Bucket Test must only be done on clear nights, so check the forecast. If it rains, the pool bucket test won't work. If it rains, run the test again.
We suggest running this test with the pump off for 24 hours and then running the test again with the pump on for 24 hours. Write down the results! This helps us to narrow down were the leak might be and can save you money if you need us to find it.
