Abstract A drain for connecting a toilet to a discharge pipe includes a cylindrical drain body having a flange extending normally from the upper end thereof. The bore of the drain body is tapered at the lower end, and threaded above the tapered portion. An inwardly directed annular shoulder at the lower end of the drain body defines a lower opening which receives the discharge pipe freely therethrough. A sealing gasket disposed within the bore about the discharge pipe is bevelled at the lower end to mate with the taper of the bore. The upper end of the gasket is bevelled to mate with a correspondingly bevelled washer which is exteriorily threaded and secured within the bore. The flange includes a plurality of holes therethrough for receiving the mounting lugs depending from the toilet, and includes annular slots extending from the holes which permit securing the toilet to the drain by rotating the toilet to secure the lugs in the slots.
