Most water heaters fail within 7 –10 years, some 5 million failures every year. Without a WAGS valve, a leaking water heater keeps refilling— and leaking. The WAGS valve is designed to shut off the water supply (plus gas supply for gas-fired heaters) in the event of a water leak from a hot water heater, thus minimizing water damage and possible gas leakage.
Easily installed on all styles of water heaters, the reliable WAGS Valve is fully mechanical and requires no external power supply. The WAGS Valve sits in a drip pan under the water heater and is activated when leaking water accumulates to a predetermined level in the pan. Once activated, the valve shuts off the water and gas supply, indicated by a red pop-up tab. And it's backed by a $1,000 Lifetime Protection Policy.
