Thanks for the advice.

I did let the pool heal itself. In some places I helped (nursed) it along with a squeegee. It took several hours but I have no creases.

The pool installer told me there shouldn't be a problem with my pool if I removed some of the liner & inserted a cut-off hose into it to pump water. Although I trust this guy (has installed many pools over the last 20 years), I didn’t need to do it. He was going to come to my house if the pool ’t heal itself.

Here is some additional information about my pool. My pool is a diving one, 8.5 feet deep, 16 X36 feet rectangle, & installed in 1990. It has vertical walls on all sides including sloped areas in the deep end. The walls are steel and the sloped areas & bottom were done with pool cement. There’s only foam under the steps in the shallow part of the pool. I was there when the pool was installed. They had to “carve” sections of the bottom of the pool into bed rock.

Two years ago I replaced my original liner (good shape but bleached) with one that is a little thicker. When they removed the original liner, we all were surprised how well the pool looked underneath! No repairs were needed. The person who originally installed the pool also did the new liner and advised me with this problem.

The vinyl liner had lifted in spots in every section (floor & sides). The worst area was the slopping side under the dividing board, a section about 12 feet long 2 feet wide. I would’ve probably attacked this side first with the pump but it corrected itself. The other sections varied but much smaller than the one under the dividing board.

Based upon previous advice I received from the installer, I only let the pool fill up to & near the liner track & then dump the water. He told me that water can get behind the liner if you let it overflow.

I normally don’t have problems with the liner lifting since I believe the drainage is pretty good. Who knows what happens with the water table but we’ve been in a drought for the last 3 years. My pool guy told me that the new liners, although you can get them thicker, are not as good as the old ones since they’re made with a different formula.

We’re currently waiting for Hanna. Is there a way I can prevent the liner from lifting with this one? Thanks
