Here's a typical wax gasket with the plastic horn. Without this gasket, sewer gas or wastewater would flood your house. The Wax Gasket & BoltsĪ wax gasket is used to make a permanent seal between the flange and the bottom of the toilet. Gently lift the toilet off the flange keeping the shims in place. Using shims if necessary, make the bowl level. As such, I uncrate the bowl (the tank and the bowl are two parts - unless you have a one piece toilet) and simply set it on the flange.ĭo not use the wax gasket at this point (don't worry, I'll explain!) Set your level across the bowl side to side and front to back. If the flange is too high, too much of the wax will get squeezed out as you press the toilet to the floor. If the flange is too low or sits flush with the finished floor, the underside of the toilet may not contact all of the wax in the gasket. The top of the toilet flange should be 3/8 of an inch higher than the finished floor surface in the bathroom. The height of the top of the toilet flange is critical with respect to achieving a seal so no sewer gas leaks into your home.
