Marketing InformationThe Studor® Maxi-Vent air admittance valve with push-fit rubber connector offers a simple drain and waste venting solution. Designed for use as an individual, branch, circuit or stack vent, the Maxi-Vent can fit both 3 and 4 in pipes. 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 Maxi-Vent closes naturally due to gravity, preventing the circulation of any bad bathroom or drain odors.
