Abstract: A timed water control valve system for use with a shower, which comprises a valve body within a housing having a water flow passage with a water inlet for a source of water and a water outlet for a device to dispense water, which water flow is to be time controlled. The valve body includes first, second and third spool passageways, with the three spools therein tensionally positioned in their respective spool passageways and adapted to move slidably between a water flow position and a non-water flow position. A timer having a rotatable shaft is connected to a knob which on rotatable movement activates the timer to a preselected water flow time period for the flow of water. The knob is also moved between an inward, water non-activated position and an outward, water activated position; first and second cams about the shaft and between the timer and knob permit the rotation of the knob.
