HOW DOES A HUGE WRINKLE GET IN THE DEEP END

[Bowlin69]

How does a very significant wrinkle/crease get in the deep end of a 27000 gallon pool and is there any way of getting it out??? This sux one problem then the next Calgon take me away.

There can be lots of causes. Was it there as soon as the pool was filled or did it show up later?

If it was there from the start, it can be incorrectly sized hole/liner or lack of vacuum while the water was going in.

If it appeared later, it could be from ground water "floating" the liner or from improper chemistry causing the liner to swell.

ground water floating it in the deep end? Is there a way to fix the issue?
