The flange has four screws attaching it. Two are larger than the other. Two of the screws do come out relatively easily, but the other two seem to just rotate in place. I'm guessing these are bolted on from the bottom (in other words, inside the floor). So, it doesn't look like I can remove this flange easily! Especially with 1" ceramic tiles on the floor. Since this is a 2nd story bathroom, any pipe access from the bottom would require a hole in the kitchen ceiling. Definitely not an option!
I don't want to leave it as-is and hope for no leaks. It's more a matter of deciding if it's worth trying to remove this flange to replace it, using some kind of "retrofit" flange that really wasn't made for it, or looking for some kind of repair kit. I have some industrial CA adhesive that would possibly weld the pieces back together, but I know it won't take that kind of stress.
There is this device:
But I don't know if it would apply to what I have.
Any other ideas?
