We recently got record rain. the yard flooded and water must have gotten behind my liner...it has come loose on the oval ends and is falling in. There are bulges where water is behind the liner...it's a mess. I have an oval inground pool about 18000 gallons and the liner is three years old. Anbody have experience with this...can it be fixed or will the liner need to be replaced completely? Pool repair people are coming monday to look at it.
