Cast iron floor closet flange is designed as a replacement flange for broken cast iron flanges. The flange simply installs into cast iron piping and the tapered design allows the rubber gasket to compress on all types of cast iron piping.

Once the toilet is resting on the flange press down firmly near the back of the bowl rim to deform the wax ring and seal the connection. Though above floor installation is considered the right way to fit a flange some swear by attaching it level with the floor. The oatey twist and set 4 in. This is very important.
