Aquaguard WAGS ValveWAGS Valves from Aquaguard can stop a leaking water heater tank from continuously refilling and dripping, or until the tank fails catastrophically. The shut-off valve halts the incoming water supply, and on gas-fired units, shuts off the gas supply to ensure the home’s safety from water heater failure. They are mechanically operated; meaning no maintenance, no electricity, or no battery checks are required. They sit in a drip pan under the water heater and are activated when leaking water accumulates to a predetermined level in the pan. Once activated the industrial-duty, one-shot safety valve shuts off the water and gas supply
