Hi everyone, I've come across this forum and am really hoping someone may be able to help me out? I've had this 18x36 pool for about 8 years now and here's the problem that came up Sunday. We've had a bunch of rain for about 4 days straight last week and noticed liner floated up last Friday. It starting drying out here Monday so I waited a few days until liner settled back down with a few wrinkles but not to bad. The problem is the water has leaked out to top part of returns and just below bottom of skimmer and stopped there. I ran hose for a few of hours and it did not move the water level at all! I checked the 2 skimmers and water in to the top of the baskets. Got cold here last couple of nights so turned off skimmers and just ran from main drain. I have the multi-port valve on recirculate. (hole in sand filter, so will replace in spring) There is a good bit of air in pump and blowing out returns. I would estimate air when running in about top !/4 of basket. I don't get home until after dark so have not been able to really give a good inspection with a flashlight. I know this a long post but I would really appreciate it if someone could give me some help on what may be happening? Thanks ( btw, liner and pump less than year old)
