I've been losing water in my pool for several weeks now. It happens only when the pool is on. It will drop 1.5-2" in a normal filter cycle. I don't have any visible leaks at the pool equipment and no bubbles in the pool. If the pool is not running for a full day the level does not drop. Are there any quick things I should check myself before calling a leak detection company? someone suggested it might be my backwash valve....but they weren't looking at my pool and I'm not sure what to check for there...
any advice is appreciated
