Abstract
An improved tempered water mixing system comprises a thermostatically operated main mixing valve for blending cold and hot water supplies during normal system operation, a secondary temperature-limiting flow-control device in the form of a thermostatic valve (also known as a pressure-regulator), with the thermostatic valve and the pressure regulating valve being connected to function as fail-safe devices so as to provide an uninterrupted discharge outflow at a substantial flow rate in the event of a malfunction of the main mixing valve.
