It's history. Chlorine makes the vinyl shrink when you drain them. It will
more than likely tear out at the top if you continue to fill. Been there
done that twice.

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.
