1. A device for remotely shutting off the flow of water from an external water supply to a water heater, the device comprising:

  • a substantially sealed housing having an inlet, an outlet, and a fluid tight chamber disposed between and in fluid communication with said inlet and said outlet;

    an inlet pipe mounted to the housing inlet, said inlet pipe operable to allow fluid communication between the external water supply and the housing chamber;

    an outlet pipe mounted to the housing outlet, said outlet pipe operable to allow fluid communication between the housing chamber and the water heater;

    a valve unit disposed within the housing chamber between the housing inlet and the housing outlet;

    an antenna capable of receiving an externally transmitted first signal and henceforth communicating a corresponding second signal;

    a solenoid capable of receiving the second signal communicated from the antenna; and

    a power supply source connected to and capable of providing electrical energy to the antenna and the solenoid,wherein, upon the antenna receiving a first “

    off”

    signal, the solenoid actuates the valve unit to a closed position, thereby preventing the flow of water through the device, and wherein, upon the antenna receiving a first “

    on”

    signal, the solenoid actuates the valve unit to an open position, thereby restoring the flow of water through the device.
