ABSTRACT:
A temperature controlled water recirculation system includes an adjustment valve for adjusting the quantities of water received from hot and cold water lines are fed to a shower nozzle. A controller, such as a temperature sensor, a timer, fluid flow meter, or the like is used for establishing the point at which a diverting valve diverts water from a recirculating return line to a shower nozzle. The return valve, therefore, determines at point in time recirculation ceases and dispensing of the water commences. In this way, water is conserved by recirculation of mixed water which cannot be used because its temperature is below or above a pre-selected threshold temperature.
