When a water heater starts to leak, it will not stop trying to produce hot water. In a worst-case scenario (a major leak with no one home to notice it), the damage can be severe. Taco’s WAGS valve senses such leaks to prevent this type of damage and provide peace of mind. The WAGS valve should be installed in a pan at the base of a water heater. All incoming supply water goes through the WAGS valve before it enters the water heater tank. When water levels in the pan get close to one inch, the valve cuts off the water supply so that the tank will not continue to refill. The valve cannot stop a leak, but it can limit damage to that caused by the water already in the tank. If used on a gas or oil-fired water heater, the WAGS valve must be used in conjunction with Taco’s GOKIT7200-1, which shuts off the supply of gas or oil to the unit.
