Well I opened the pool last weekend and everything looked great. I vacuumed the pool yesterday and woke up to a pool at least 4 inches lower than when I went to bed and I watched it drain at least another inch until it started raining. I know that liners get holes but what really frustrates me is that we replaced it last year when I opened the pool because the same thing happened. At least last year I know that the liner was old and when it came off the sides were full of tiny holes. Now I just want to get a lot of dirt and be done with pools forever! I guess I will just let it drain until it stops and if I cannot fix the hole I am finished. We are in NJ so we only get about 2 months out of it anyway. Thanks to everyone here at least I know how to find and fix the hole, but what a pain in the butt.
