Thanks for the detailed response! Yes, it is only liner bulges,nothing structural that i can see. And fortunately it appears the liner is somewhat staying place...the bottom corners are all still where they should be, just the liner bulging away from the walls

Before you attempted to push out the wrinkles, did the ground water receed eventually naturally out from behind your liner or did you have to pump that out?

The water has been receeding some, but its still rained everyday so my bulges continue to stay. Everything is holding in place as far as the coping in the liner track and the steps.

I tried earlier gently and easily pushing on the bulges from the floor to the top w my pool broom, but it only moved the water towards the bottom or down the wall.

I also have some photos of my problem but im not sure how to add them here.

Thanks again!
