Abstract
An apparatus for preventing freezing of interior water pipes. A thermal switch is attached to a hot and/or cold water supply pipe in a remote location that is prone to freezing in cold weather. The thermal switch electrically communicates with a power source and with a solenoid-actuated valve. The solenoid-actuated valve is located in a conduit communicating the outlet of the water pipe adjacent a water usage station with the water outlet of a fixture located at the water usage station. This conduit is separate from the existing supply line communicating the outlet of the water pipe with the fixture and does not, therefore, interfere with the normal operation of the fixture.
