Abstract:
1. In combination with an appliance having a water supply line, an automated water disabling valve comprising: a hollow shell in fluid communication with said water supply line, said shell having an inlet, an outlet and a conduit extending therebetween; a sensing means for determining if water is flowing through said shell, said sensing means including a channel extending from a first position on said conduit proximal said inlet to a second position adjacent said outlet, said channel including a throat therein, said sensing means further including a spring-biased magnet received within said channel and a Hall effect device positioned exteriorly of said channel and proximal the throat whereby water flow through said conduit results in a pressure drop within said channel forcing said magnet into said throat to disable flow therethrough while simultaneously actuating said Hall effect device indicating that water flow to said appliance is occurring; a disabling means in communication with said sensing means for disabling water flow through said shell if water flow through said shell continues beyond a predetermined duration.
