Ok. I finally figured out that my suspicion was correct. My water level would stay the same until I pumped water off the coverthen it would seem to be lower. We had bad storms last night and I noticed today that the cover clips had come off in a few spots and the cover was undone (I WILL NEVER USE THE COVER CLIPS AGAIN, THEY ARE HORRIBLE). Anyway, I look in the pool and what do I see, only about 6 inches of water left in my pool. My husband pumped excess water off the cover last weekend. My new question is how quickly do i need to get the hose in this pool before the liner messes up? My pool is almost 7 years old and since the water is not currently up very high I can feel that the liner is not touching the wall. I just don't know how flexible this thing will be after 7 years. I didn't want to put too much water in because I wanted to check better for leaks before a complete fill-up. Anybody have experience with this problem? Thanks in advance.
