Closet flange

In plumbing, a closet flange is a pipe fitting that both mounts a toilet to the floor and connects the closet bend to a drain pipe. The name comes from the term "water closet", the traditional name for a toilet. Closet flanges are typically made of brass, cast iron, ABS, PVC, and lead. In a typical installation, the closet flange is mounted on top of the floor with the hub fused around the drain pipe. A wax ring is used to seal the gap between the flange and the bottom of the toilet. The toilet is bolted to the flange, not to the floor.
