    Abstract: The new product improves upon a standard pop-up drain stopper which is controlled by a horizontal pivot rod as is used in bathroom/lavatory sinks. The stopper has a bell receiving base threaded to match a like threaded male ā€œLā€ shaped pivot rod allowing the stopper removal or installation to be done without removal of the pivot rod to clear a clogged drain. The invention is installed by inserting the ā€œLā€ shaped directional rod into receiving port of drain tube then inserting the threaded stopper on to the threaded pivot rod and turning in a clockwise motion until fully seated. To remove, push lever downward to raise stopper to apex and turn in a counter clockwise direction and lifting out of drain opening. This allows cleaning of drain clogs without disassembling the mechanical components located under the sink as is required to remove the typical pop-up stopper.
