Abstract

Apparatus for automatically shutting off the water supply to a leaking water heater includes a water collecting tray positionable beneath the heater, a valve mechanism attachable to the tray, a float mechanism, and an action arm interactive between the float mechanism and valve mechanism. When water collects in the tray, the float mechanism rises, causing the action arm to trigger the release of a spring-urged component of the valve mechanism to discontinue flow of water to the heater.
