Hi, I'm new to this forum. It seems there is a lot of good advice & I sure could use some. Our pool has been leaking for a few weeks. It leaks whether the pump is running or not. When the pump is running bubbles come out of the returns. It leaked below the skimmer level while running one night. We turned it off. It is now down another 2.5 inches.
We had a hole in the tubing, we replaced it and there seemed to be no more leaks above ground.
There is no leak around the filter, the filter basket, the backwash drain, none of that stuff.
My husband and I checked the skimmer and there are no cracks below water level. There is one at the concrete, but the water level leaks far below that.
Would a leak with the main drain cause bubbles from the return?
The water is still above the light, but would a leak there cause bubbles from the returns?
I think it's the main drain, but I'm not a pool expert.
We appreciate any help. Please.
