Abstract
Abstract A valve mechanism is disclosed which selectively controls the flow of water from hot and cold water pipes to a remotely located appliance. Actuation of the valve mechanism is controlled by a timer that is generally mounted within the appliance. The valve mechanism has a pair of inlet ports and one exit port. The inlet ports are connected to the hot and cold pipes. A single section of flexible tubing is detachably mounted between the exit port of the valve mechanism and the remotely located appliance. A housing which is attached to a wall or another suitable surface and having a pivoted front door is provided to enclose the valve mechanism. Preferably the housing is flush mounted in the wall.
