ABSTRACT:
A device includes a housing that has a plurality of monolithically formed walls, wherein selected walls are provided with inlet and outlet ports respectively. The housing includes a coupling in fluid communication with the inlet and outlet ports, a mechanism for detecting a fluctuation in water pressure, and a mechanism for selectively prohibiting water flow. The prohibiting mechanism cooperates with the detecting mechanism. The housing also includes a mechanism for providing an audible notification when the water supply is toggled between interrupted and reinstated modes and a mechanism for manually controlling the prohibiting mechanism. The manually controlling mechanism is electrically coupled to the prohibiting mechanism. An internal power supply source supplies power to the detecting mechanism, the prohibiting mechanism, and the manually controlling mechanism. A diode is attached to the housing and is illuminable when the power supply source reaches a minimum threshold level.
