ABSTRACT:
Apparatus for detecting a discharge of water such as a leak in a device containing a relatively large volume of water such as a hot water storage tank having a pressure relief valve and for shutting off the water supply to such device in response to such detection. The apparatus includes a relatively shallow pan located in proximity to the bottom of the device for collecting water discharged from the device either from a leak or from opening of the pressure relief valve, a float switch mounted in the pan for detecting the presence of water in the pan above a predetermined level and a shut off control valve for disabling the water supply to the device upon activation of the float switch.
