Pool has been leaking since I opened it this year. Currently losing about 1.5" per day.
I thought the problem may have been with the gaskets around the stairs, Yesterday I used the A-B epoxy putty to seal up the entire area where the liner and stairs meet. Confirmed no leaking there with a dye test.
Last night, I plugged both skimmers, the main drain, and both returns. Lost .5" in 8 hours. None of this loss was through evaporation, the level in bucket did not change.
Am I right in thinking that this has got to be a liner leak? In the deep end, there are some wrinkles that look like they have some water underneath. But they are rather small and I can't imagine I'd be losing 1.5" of water in a 40x20 pool through those, considering the water also has to get through the concrete under the liner.
Any ideas on what I'm missing? What size hole/tear should I be looking for to be responsible for so much water?
