I have a 32 x 16' inground vinyl lined pool. About 4' worth of 3' deep shallow end, sloping down to 5' for the rest of the pool. The liner is about 13-14 years old, but apparently still in extremely good condition.
Didn't open it last year, but this year we pretty much have to. With the leaves et. al., the volume of crud in it was so bad, that it was thought best to drain it almost completely, shovel out the crud, and then refill/skim/vacuum/shock/etc.
Drained it down to about 6" in the deep end, and cleaned it out.
The vinyl has pulled away from the sides, and there's some wrinkling on the bottom along the sides and in the shallow end corners. The vinyl along the central portion of the pool has not moved.
Assuming that refilling the pool will "reseat" the vinyl, I've started refilling again.
I'm up to about 4" in the shallow end.
Some of the wrinkles have virtually disappeared, and the biggest ones in the shallow end seem (but I'm not sure) to be smaller.
Is it safe to assume that it will reseat? Or should I stop refilling and figure out some way to physically stretch the bottom vinyl towards the corners and thus pull the wrinkles out? How do you do that anyway? Suction cups?
Thanks in advance.
