I have an above ground 24' pool. The liner goes in a small slit and hooks on I believe. I would really like it if someone can tell me how to install. Not real sure. How do I get the liner tight to the wall. Less wrinkles? When to cut holes for skimmer and water return? Is the walls breaking a big problem from too much water pushing on it? Please help! Any info. Would be greatly appreciated.

Replacing a pool liner requires several friends and some skill and knowledge. This link gives good advice. How to Install a Replacement Vinyl Liner I have never tried to replace a liner without at least 4-5 friends and several six packs.
