  • Patent number: 5638847
    Abstract: A water supply control apparatus includes a flow sensor, connected to a supply line of an indoor plumbing network, which sends a flow signal to a controller when flow is detected. The controller includes a power circuit which is interrupted upon detection of flow, thereby causing a shut-off valve to close. Moisture sensors and temperature sensors can also be coupled to the controller so that the shut-off valve can be closed in response to the detection of moisture or an incipient freeze condition.

  • Patent number: 5402815
    Abstract: A water supply control apparatus for a household plumbing system having a main water supply line includes a shut-off valve disposed in the main water supply line, electric motor means for actuating the shut-off valve and being operable to move between open and closed positions, at least one temperature sensor adapted to be located in a position of exposure to cold temperatures, at least one moisture sensor adapted to be located in a position of exposure to water leaking from household appliances, control means, connected to the electric motor means, the at least one temperature sensor and the at least one moisture sensor, for actuating the shut-off valve to the closed position when either a freeze condition is detected by the at least one temperature sensor or a water leak is detected by the at least one moisture sensor.

  • Patent number: 5240028
    Abstract: An automatic water supply shut-off system includes a shut-off valve movable between opened and closed positions in a line leading from the water supply. An electric motor actuates the shut-off valve and is electrically connected to a power source through an electric circuit so that when the circuit is closed the electric motor actuates the shut-off valve into the open position to allow water flow through the line. At least one temperature sensor feeds a signal to a logic circuit that controls a switch. The switch cuts off the supply of power to the electric motor when the sensor senses a temperature corresponding to a freeze condition.
