Hey guys, my water level keeps dropping I would say half an inch per day (no swimming) Ive come to believe I have a leak somewhere. I think it may be in the liner because I have air or water pockets that seem to come and go in the deep end. Well I'm hoping its not a plumbing issue. Does water behind the liner indicate a liner leak? Or plumbing? My pool is 16X30 in ground. 32000 liters I believe. 3 feet in the shallow and 6 feet in the deep. Any help or suggestions would be great.
