The Watts half-inch brass vacuum relief valve helps prevent damage to water heaters and tanks by allowing air to enter pipes and relieve vacuum buildup within tanks. Made of corrosion-resistant brass with a maximum working pressure of 200 pounds per square inch, this valve helps equalize air pressure differences that can form when water drains from pipes and tanks. Installing the valve is a simple way to safeguard plumbing systems.
