I'm mounting a floor mount, back outlet toilet and I'm conflicted by which type of wax ring to use. The manufacturer's instructions seem to call for a plain wax ring, but I read a post on the forum saying that a plain wax ring could sag over time in a back outlet install. The big box store also sells a #3 reinforced wax ring with a plastic funnel on it. The box says it's for back outlet toilets. I've read here about problems with the ring that has the plastic funnel (perhaps I can cut the funnel off?), so I hesitate to use it.
Should I go with either of these options or is there another type or ring I should be using?
