Remedy For Sagging Pool Liner?

[viggen_eh]

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.
