I have inground pool which was built in 1993. I need to add about 1/2" of water every day. Pump runs 8 hours per day. We got the liner replaced last year. When pool was opened in the spring, water level was about the same when it was closed so I suspect the water leak is not at the light or bottom drain.
How can I locate the the leak if it is in the underground piping or where else can I check to fix the leak?
