I am losing water at about 1" per day from my in ground pool. Also, when the pump is on, dirt is coming in. I can't see it but it accumulates overnight. My pool guy said to cap the return line and shut it off at the filter (there are two pipes to filter for 4 lines). He said to use process of elimination, but I am pretty sure I know what side it is on since the yard is very moist in that area.
The sand and laterals were changed last week, so it's not that.
He said that it is a broken return line most likely and this will put a band aid on it. The water drops even if equipment is turned off. Any thoughts? Thank you!
