Air Admittance Valve Tubular Tee with Redi-Vent

The Studor Redi-Vent Air Admittance Valve with Tubular Tee Adapter offers a simple drain and waste venting solution. Great for venting a single fixture or a group of bathroom fixtures, the Redi-Vent with tubular tee adapter is designed to fit 1-1/2-inch pipes and excels in tight applications. This 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 closes naturally due to gravity, preventing the circulation of any bad bathroom or drain odors.

An air admittance valve shall be acceptable as a vent termination for any individual vent, common vent, circuit vent, loop vent and island fixture vent that is provided to prevent siphonage of a fixture trap. An air admittance valve can be used as an alternative to extending a vent through the roof (or sidewall) to the open atmosphere.

The air admittance valve shall be located a minimum of 4" above the horizontal branch drain or fixture drain being vented. Each valve should be installed in an accessible location.
