We opened our pool to find a major leak. After filling. Loosing 4-5 inches in 24 hours. It is a fiberglass pool only about 3 years old. We had a small leak that was repaired last year caused by a small crack in one of the jet returns. This year with the significant amount of water loss someone came out to find out plumbing to the return jet has actually collapsed right at the shell of the fiberglass . Is there a way to fix this without digging up the concrete? It’s fine if we never use that jet again. We have 3 others, but I can’t afford to keep loosing water. I attached pictures of what is happening with the pipe.
