ABSTRACT:
A drain valve assembly adapted for use with sinks, lavatories, and tubs is disclosed. The drain valve assembly comprises a valve body or drain sleeve which is mounted in the drain port or opening of the sink, lavatory, or tub and includes a valve seat formed around its open upper end and a stud axially mounted within the drain sleeve. A removably mounted stopper is positioned within the drain sleeve for axial reciprocation on the stud. The stopper is provided with gripping means which cooperate with stop means formed on the stud for holding the stopper either in a raised or open position or a lowered or closed position. A resilient seal means is mounted on the stopper for seating in fluid tight relation with the valve seat at the open outer end of the drain sleeve when the stopper is in the lowered or closed position.
