Introduction AIR ADMITTANCE VALVE Air admittance valves are pressure-activated valves that allow air to enter into the drainage systems. These valves are one-way valves and allow movement of air in only one direction. The air that enters through air admittance valves prevents the siphonage of the traps. The valve allows the air to enter only…

Introduction AAV VALVE FOR VENTS AAV Valves are Air admittance valves that deal with the negative pressure building up inside the plumbing systems and prevent the siphonage of traps. Siphonage is filling up of liquid in a container placed in the lower position, thus filling up of the traps.AAV air admittance valves are installed after…
