Last week we experienced heavy rains. The ground water rose and entered behind the vinyl liner. I now have severe wrinkels to the liner on the floor and sides. Short of emptying the pool is there anything that can be done.
That's tough to fix. Sometimes you can get inside the pool and manipulate the liner to get out wrinkles. I have heard of folks using a bathroom plunger to "grip" the liner and move it but I have never tried it.
