matcin2531,

Thanks for the input.

I'll give it a go and see what happens. I'll try to enlist some help to push from the outside while I tighten while standing inside the pool.

Anothe rtip I was given was to do the bottom screws first as this will draw the gasket properly into place.

AND.... the butterfly gasket goes directly on the metal part of the pool walls and NOT overlapping the liner on the inside.

Thanks again.
