Abstract: An improved drain stopper valve assembly is disclosed that replaces the conventional drain stopper and includes an integral strainer that completely surrounds the underside of the stopper valve. It has perforated, tubular upper and lower sections that connect together via a bayonet coupling that enables easy disassembly for cleaning or removal of debris or a lost object. The lower section of the strainer body is also tapered to enable freer flow of liquid through the stopper valve assembly even if the lower section is filled with debris that has been strained. The replacement stopper valve assembly is designed to fit all standard basin drain plumbing, and to be easily removable from the drain.
