Shipping Details

With its compact design, the Studor Redi-Vent Air Admittance Valve with PVC 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.

Compact air admittance valve with PVC adapter; ideal for a single fixture or group of fixtures up to 20 DFUs (drain fixture units) on a branch
Uses gravity to automatically close seal and prevent circulation of unpleasant bathroom or drain odors; exclusive vermin protection system keeps out bugs and foreign objects
Creates ventilation that prevents the loss of water seal in trap
For Venting single fixtures, kitchen sinks and bathroom groups including back to back applications up to 20 DFU
Exclusive vermin protection system
Expands architectural design limits
Compact design for tight applications
Limited lifetime warranty for replacement of defective valves

Works great

Drain was going down slow. Installed the new vent without any problem. Pretty straight forward. The drain goes down quicker than it did before.

No more stinky kitchen sink.

Would Recommend

I got this because the old one that we had underneath our kitchen sink had finally gone caput and this is actually the smaller version of the one I had down there, but it was the only one in stock at Lowe's and we desperately needed it switched out because the raw sewage smell was stinking up the place. Got it, outrageously easy to install, and once it was in place, smell was gone instantaneously. Does the job and hope it'll last another 20 years like the old one did.
