ABSTRACT:
An improved drain valve is disclosed for selectively sealing a conduit. The drain valve comprises a drain housing installed in a bathtub or the like, latching means threadedly coupled to the housing and a combination drain stopper and actuator coupled to the latching means. A locking member coupled to the latching means is adapted to allow the latching means to threadedly engage the drain housing, but prevent disengagement therefrom, without the use of a tool specially made to release the locking member. Upon release of the locking member by use of the tool, the latching means and combination drain stopper and actuator may be disengaged from the housing.
