My plaster inground pool has simple 5 1/2" main drain cover that stays in place using friction. There aren't any screw holes.
My wife wants to replace the cover with one of the newer style covers that won't kill the kids. My problem is that I'm going to need to have some place to screw the new cover into.
Is there something that I can do with waterproof epoxy? I'd like to do this project by myself to keep costs down.
