Just installed a brand new liner. Looks perfect. Filled the pool up and already dropped like 4 inches in one day. Dropped past the skimmer so I know that’s not it. I’ll know in the morning but it hasn’t dropped past the bottom of the return. The gaskets looked good when I reinstalled it and I tightened it pretty good. I don’t see any leaking on either side, but is it possible for these to leak? It’s a 12x24 pool so 4” or so in a day is a lot of water going somewhere I just can’t figure out where. I live in so-cal so no crazy weather and no signs of rust either.
