So the pool is losing 3 inches per day I ran fix a leak and another product both ways or I reverse plumbed it and no luck. I also used an underwater epoxy and completely epoxy the niche. Since I saw water running into the pool from the niche before I opened the pool last year. I also ran fix a leak last year as well. All was ok for a while but the end of season it was back. I removed hydrostatic valve and put a plug in it with no luck. I am at my wits end
