We are going to install a new liner in an above ground pool this weekend. I have read conflicting information as to when the skimmer and jet holes should be cut. Do you fill the pool with water within a foot of the skimmer, attach the trim kit and then cut out the liner? I don't know what to do, and I'm worried about damaging my new liner. Can anyone give me some advice as to when you do this step or any advice in general. Thanks!:)
