Description
The Watts 0556031 N36 3/4″ Vacuum Relief Valve is engineered to protect water service piping and equipment from the damaging effects of negative pressure (vacuum) conditions. When a vacuum forms in a water line — due to sudden shutoff, backflow, or system drainage — this valve opens automatically to admit air, preventing pipe collapse, siphoning, and contamination of the potable water supply.
