Studor® Air Admittance Valve Box Kit

Product Description and Features

Connect and conceal your air admittance valve with the Studor White PVC Air Admittance Valve Recessed Outlet Box with Redi-Vent and Louvered Frame. This recessed outlet box is designed to be installed in the stud bay and comes with an accessory grill faceplate that keeps the included Redi-Vent AAV (air admittance valve) hidden from view. The one-way valve automatically opens and takes in fresh air when negative pressure (suction) occurs from a fixture discharging into the plumbing system. When the water flow stops, the Redi-Vent AAV closes naturally due to gravity, preventing the circulation of any bad bathroom or drain odors. With a capacity of 20 DFUs (drain fixture units) on a branch, this economical negative pressure valve creates essential ventilation that prevents the loss of water seals in traps, eliminating the need to install expensive and unsightly roof penetrations and vent piping.
