The mechanism of operation of air admittance valves is gravity. The waste and water flowing down the conduit produce unfavorable air strain in a drain line. The inflow of air into the sealing gasket, caused by the adverse pressure, helps the unrestricted drainage of the waste.
Thus, it enhances the valve’s efficiency and prevents odors from escaping from minute areas. The Studor AAV can be utilized in lieu of expensive and complex plumbing (open pipe) vent techniques that penetrate roofs of buildings.

In this position, no air enters the AAV, and no sewer gases escape. The vents have the added job of maintaining an equalized strain inside plumbing systems. Manufactured particularly for chemical waste techniques, the Studor Chem-Vent Flame-Retardant Polypropylene Air Admittance Valve with Tailpiece is a good selection for venting “island sink” chemical basins.
