Okay, so I have read all through the other posts and how to establish where a leak is coming from, etc. We just got a new pump, new skimmers and a new liner, so the leak could be in a whole host of places. I turned the pump off and it is still losing water so from my research it has to be either the skimmers/skimmer plumbing or the liner, right? I have called the company that put the liner in and they said to keep an eye on it for one more day. Here is a maybe dumb question. The liner stretches, right? Is it possible the weight of the water is just taking a little longer to stretch the liner and perhaps that is the reason for the drop in water? It dropped about an inch in 13 hours and another 1/3 of an inch in 7 hours. And if there is a leak, how do they figure out where it is coming from? I'm paranoid water is going to get behind the liner too. Should that be a concern? I'm so frustrated because it looks so good and we have spent all this time and money trying to get it all fixed up just to have this issue.
