Extreme HELP NEEDED!!! We put my pool up and started filling up during the day and was going to let water fill up overnight when we notice at night that my wall started to cave in by the skimmer. My liner where my skimmer hole is extremely tight, so I don’t know if thats what’s pulling my wall inwards, but it always is messing my legs up to. (This ofcourse is all taking place at night) Should I drain my 4-5 feet water out that I have in now and loosen the liner up or what should I do?
