发明名称 Sealable drain fitting
摘要 A floor drain includes a cylindrical drain body having external threads formed thereabout and an upper flange extending radially outwardly from the drain body and disposed flush with the floor surface. A threaded nut is secured about the drain body to engage the lower surface of the floor. The drain body includes a lower bore portion adapted to receive the upper end of a waste discharge pipe, the pipe being secured therein by adhesive or the like. A plurality of shoulder stops extend inwardly from the upper end of the lower bore portion to limit the upward position of the waste discharge pipe. The upper end surface of the waste discharge pipe is substantially exposed by the shoulder stops, so that a bead of sealant may be disposed at the junction of the upper end surface and the lower bore to seal the assembly.
