Abstract: A closet flange assembly for anchoring a water closet to a floor and sealingly connecting the water closet to a waste drain conduit. The closet flange assembly includes a drain body having a flange for attachment to the floor and to the water closet and having a compression gasket circumferentially compressingly contained and held against axial movement within the axial bore provided in the drain body. The compression gasket has an axial bore which provides an interference fit with the periphery of the waste drain conduit when the drain body and compression gasket are axially slidingly pushed onto the waste drain conduit.
