Water Gone From Pool
I had a new liner put in our above ground pool in the fall. We closed the pool for the winter & drain the water off the cover.
We went away over Christmas to find most of the water gone from the pool & the cover sitting way down near the bottom. Where could the water have gone? What can we do to prevent the pool from collapsing? Any thoughts or ideas?
My first guess would be a seam opened up in the liner. That should be easy to find by closely examining the bottom seam. For water to leave a pool that quickly it must have made a mess around the outside, at least a big wet spot. The wet area would indicate the area where the hole is.
When the water is low is the perfect time to get in and find the hole. If it is a puncture, and can be patched, now is the time to do it and then fill the pool up before the liner shrinks. If you find a damaged seam you will want to make arrangements to have the liner replaced.
Most well constructed above ground pools can stand fine without water. Unless the pool is in ground, then the liner should be fixed or changed ASAP.
