ABSTRACT:
In a vandal resistant push-pull drain stopper for use with a drain plug of a bathtub or other similar vessel, there is provided a plunger having an inner cylindrical bore, a stem having a reduced portion, an expanded portion and a channeled portion, an O-ring snugly nestled between the stopper and the stem; a cap threadably engaged with the stopper and axially disposed about the upper region of the stem, the cap having a relief inside the hexagonal bore portion thereof so that the stopper freely rotates about the cap by discouraging removal of the cap from the drain stopper; the plunger having a seal radially disposed about the plunger so that when the stopper is in a closed position the seal abuts with the outer periphery of the drain plug thereby sealing the same. The reduced, expanded and channeled portion of the stem permit the drain plug to be open and closed by user and provide tactile "snap in place feel" in the open and close positions while employing only, essentially, two moving parts.
