Every year I open the pool, initially I always wonder if my pool has a leak. Reason? Because I usually end up having to put a hose into it to raise the water level so that the water filter/pump does not have priming issues. I had to do it this morning ... again ... probably the 2nd or 3rd time I've had to do it since I opened the pool two/three weeks ago.
If I have a leak/hole in the pool somewhere (can't see any), shouldn't it have drained out during the winter? Also, the problem seems to slow down as the season progresses ... I would think if evaporation was the cause, it would happen MORE frequent as it got warmer. Or finally (I wonder), is my pool "settling" ... walls expanding/adjusting somewhat, ground/sand underneath settling, etc. ... and this affects the level of the water although volume has not changed.
Anyone experience this problem on a regular basis?
