Leak Detection And Automated Shutoff Systems Using Water-Soluble Materials

The present disclosure is directed to a mechanical and powerless leak detection and shutoff system that may be used in any commercially available water heater, e.g., both gas and electric. The system includes a spring-loaded shutoff assembly having a valve member operatively coupled to a fluid inlet line of the water heater. A handle of the shutoff assembly is maintained in an open configuration via a latching mechanism until a force is applied to cause the latching mechanism to release the handle and actuate the valve member to shutoff fluid flow through the fluid inlet line. The shutoff assembly is operatively coupled to a leak detection assembly via a cable. The leak detection assembly uses a fluid-soluble material that dissolves when exposed to fluid to thereby pull the cable to apply the force to disengage the latching mechanism.
