ABSTRACT:
A shower receptor drain assembly includes a generally cylindrical drain body having a flange extending upwardly from the upper end thereof. An inner flange extends radially inwardly from the lower edge of the drain body, and is provided with an inner diameter which permits a waste discharge pipe to extend upwardly therein. A plurality of bosses extend upwardly from the inner flange and are spaced equally thereabout. An annular sealing gasket is disposed within the drain body and received about the upper end of the waste discharge pipe. A compression ring is disposed directly superjacently of the sealing gasket, and a plurality of screws extend through the ring and through aligned passages in the gasket to be retained in tapped holes in the plurality of bosses. The screws cause compression of the sealing gasket to effect a leak-proof seal of the waste pipe within the drain body. The gasket includes a plurality of recesses in the lower edge thereof which are self-aligning with the bosses extending upwardly from the inner flange.
