Review on 🚽 Fluidmaster 7513: Premium Extra Thick Wax Toilet Bowl Gasket with Flange - Ideal for 3-Inch and 4-Inch Waste Lines by Daniel Roe

High enough for sub-floor mounted flange for 1/4" tile + tile backing. To install I scraped the old wax ring off the pipe flange and scraped any large chunks off the underside of the toilet .I rolled it into a ball of pure internal wax and put it on top of this ring as a precaution (sort of simulating "stacked" rings. I didn't go as far as heating the ring, but it shouldn't be colder than room temperature .Make sure the studs are on the flange and lower the toilet right down the middle.You will feel the wax ring shrink in the last 1/4"-1/2" as the base of the toilet touches the floor. You will most likely only take one shot, so take good care of it. Works great and doesn't leak. Poor quality initial install fixed.
