Hello, I had to remove my toilet to snake out my drain and now in a bit of a pickle trying to reinstall. My flange is flush with floor. Opening is about 5" diameter and then there is a lip about 2.25" down. When I try installing a standard wax ring, it just slides down until it hits this lip and doesn't even come close to hitting the surface. What should I do? Should I just keep stacking wax rings until it hits the flange? Or maybe try finding a wax ring that works with 5" hole but I dont even thing those exist? Thanks in advance.
