a valve body including a water inlet port adapted for connection to a water supply and a water outlet port adapted for connection to a point of use;
a valve unit mounted within said valve body and defining a water flow path between said water inlet and outlet ports, and further including a reciprocal valve member movable for respectively opening and closing said water flow path for on-off regulation of water flow from said water inlet port to said water outlet port; and
a pushbutton operator unit including a mounting element rotatably mounted on said valve body, and a pushbutton carried by said mounting element for relatively free rotation and for reciprocal movement with respect thereto, said pushbutton being engageable with said reciprocal valve member for respectively opening and closing said water flow path, said pushbutton having an externally exposed outboard face;
said pushbutton outboard face and said mounting element each including at least one wrench port formed therein at positions for substantial coaxial alignment with each other in a selected rotational position of said pushbutton relative to said mounting element to permit access to said at least one wrench port formed in said mounting element through said at least one wrench port formed in said pushbutton outboard face for rotatably installing and removing said mounting element with respect to said valve body.
