Remedy For Sagging Pool Liner?

[waste]

Welcome to The Forum!

Pics would certainly help me point you in the right direction

My first read on this is that you have a ground or surface water issue.

How old is the liner? (after ~ 3 - 5 years, draining is a BAD thing to do!)

Please give me some more info and I'll do my best to help you.

No apparent groundwater issue - liner is on concrete liner, but is old. No water accumulation under liner. It is severely wrinkled and my best guess after reading the threads is that the wrinkles are chemical in origin. Have now re-filled the pool and liner is not bagged on sides as much.

Good to hear.

Please keep up on the chemistry so you'll get the longest life out of your liner.
