With its compact design, the Studor Redi-Vent Air Admittance Valve with ABS Adapter offers a simple drain and waste venting solution. Great for venting a single fixture or a group of bathroom fixtures, the Redi-Vent air admittance valve is designed to fit 1-1/2- and 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.
