Abstract
A drain stopper assembly that can be simply pushed into and pulled out of a drain pipe includes an open-close mechanism, a cap, a drain seal, and a means for engaging the open-close mechanism with the drain pipe and preferably also includes a strainer. The means includes a wheel-shaped disc that rests on crossbars in the drain pipe and has an annular seal about its perimeter; a ball-and-spring detent mechanism for attaching the drain stopper to crossbars; and a magnet attached to the open-close mechanism, preferably with a ferrous adapter for the drain pipe. The open-close mechanism is a push mechanism, a lift-and-lock mechanism or a lift-and-turn mechanism.
