This is only our second spring with a new AG 24' vinyl lined pool. Winter of 2013-14, had a ton of snow here in Illinois and our pool was practically overflowing in the spring. We are using a cover that allows water to slowly seep through. Used the same cover this past winter where we had quite a bit of snow, and I recently noticed that the water level seems WAY lower than I remember it being when we closed it. I know we went below the return by a few inches, but now it is probably a foot below (at least) the return and I am wondering - is there leak somewhere?
We have a floor drain. We closed the pool ourselves - blew out the lines, added antifreeze - tried to follow the instructions thoroughly. Now I am wondering if something under the pool burst and is leaking, do we have a liner leak, or what? The ground around the low side of the pool is damp, but it isn't a swamp and that area is often shaded so I don't know if it is from the pool or not.
What should we do? The water is getting so low, I am concerned about it going any lower and the walls collapsing. Should we remove cover and look for liner leaks? Add more water? We are supposed to get a bunch of rain over the next week...
