  • Plumbing flood control system
    Patent number: 6523562
    Abstract: A control system for stopping a plumbing-related flooding situation in a building includes at least one sensor for accumulating water and producing a low voltage electrical control signal when sufficient water is accumulated. An actuating system receives the control signal and in turn routes 110 volt current to an electrically activated valve located in a main feed conduit of the plumbing system. The reopening of the valve is achieved by a manually operated electrical switch.
