ABSTRACT:
A water supply failure protection valve is connected to hot and cold water supplies. The failure protection valve is responsive to the loss of cold water supply pressure to shut off all water flow. The failure protection valve is responsive to the loss of hot water supply pressure to permit cold water flow through both a cold water flow path and a hot water flow path so as to ensure a substantial flow of water to a downstream fixture. The supply failure protection valve may be integrated with a thermal mixing valve to provide water at a preselected temperature.
