I am hoping you can help me out. I have an inground pool, steel wall. I have a significant leak, losing about 2 inches of water or more per day, only when the pump is running. I have narrowed down the leak to the return side. I have done this by running a flexible PVC hose on top of the ground from the filter to the pool and plugging the return jet. The leak stopped with this test.
So my question is, how can I determine if it is the return jet or the pipe that is leaking? And once, I know which is leaking, can they be replaced or repaired from inside the pool with out pulling up all of the pavers and digging?
Thank you for your help.
