About Air Admittance Valve
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 when a negative pressure builds up in the plumbing system. The closing of the valve takes place due to the gravity and there is no net pressure left for the formation of a flow.
