Abstract: A water distribution valve including a cylindrical outer box having hot and cold water inlet ports and a plurality of outlet ports in the cylindrical outer wall thereof, and a cylindrical inner cup which is rotatable within the box with the cylindrical walls thereof in sliding contact with the cylindrical walls of the box. Inlet and outlet holes are provided in the cylindrical outer walls of the cup, which holes are respectively alignable with the ports in the box to allow hot and/or cold water to flow into the cup through one or two aligned inlet ports and holes and then out through an aligned outlet hole and port. The holes and ports are arranged so that incremental rotations of the cup in the box aligns different cup holes and box ports to selectively provide hot, cold or warm water to any one of the outlet ports.
