An apparatus that operates to detect the presence of a water leak in a gas water heater, and to automatically shut off both an electrically activated water supply valve and a gas shut off means in response to the detection of the leak. The apparatus comprises a float activated electrical switch positioned in a water collection pan located in close proximity to the bottom of the water heater, to control activation of an electrically operated valve for shutting off the supply of water to a gas water heater. The apparatus further comprises a gas shut off means for shutting off the gas supply in response to closure of the float activated electrical switch.
