<p>The invention relates to a shower control valve assembly which includes a casing mountable in a wall with inlets for hot and cold water. A cartridge is insertable into the casing in one of two orientations so that the hot water inlet of the cartridge can be aligned with either one of the casing inlets, depending on which one is the hot water inlet. The casing has at least one outlet for transporting mixed water to the tub and a diverter passage is connected to the outlet for transporting mixed water to the shower. An insert is positioned in the outlet and has a counterweighted butterfly valve member therein, the valve member being normally in an open position allowing water to flow to the tub. A rod member extends laterally of the insert and is reciprocable so as to contact the upstream wing of the valve member and force it into the stream of water flowing to the tub. The stream forces the valve member to a closed position and then the flowing water is forced to follow the diverter passage to the shower. When the water is turned off, the counterweight forces the valve member to resume its open condition. The rod member is rotatable and cooperates with appropriate means in the insert to effectively throttle water flowing to the shower to act as a volume control therefor.</p> |
