I have an old Anthony Sylvan inground plaster pool with a 5 1/2" main drain opening. The drain cover is seated on a lip on the drain opening and there are some tabs on the underside of the drain cover that hold it in place through friction. There aren't any screw holes.
How can I install a safety drain cover that needs to be screwed down? I would like to find a solution that doesn't require draining the entire pool. Is there some sort of epoxy that I can use to attach the base of the safety drain to the pool floor?
