Hi I have a 16x32 steel wall vinyl lined pool. 3 years ago I had all the plumbing to the pool dug up and professionally replaced, had the liner replaced and new concrete pool deck poured. This winter I have found that the pool has a leak and I have various water filled bulges behind the liner. I have been watching the water level and found it stops consistently at the same level. I am reaching out to see if anyone here may have suggestions at to the possible causes. I will be reaching out to the company that did the rehab work and want to be fully informed when talking with them.

A little more background, the pool was installed in the early 1970’s. I have been the owner for 14 seasons with no issues. This winter was typical, with no real frost, deep freeze or heavy snow issues. I have a “loop lock” mesh safety cover and the pool was closed without issue. Any help would greatly appreciated.
 
Welcome to TFP.

Any penetrations at the level the water stabilizes?
