Product Description and Features

Designed specifically for commercial applications, the Studor Tec-Vent Air Admittance Valve offers a simple drain and waste venting solution. Made of flame-retardant, high-tensile-strength polycarbonate resin, this UV-rated 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 Tec-Vent closes naturally due to gravity, preventing the circulation of any bad bathroom or drain odors.
