What Customers Are Saying
The Air Admittance Valve (AAV) is generally an effective and affordable solution for venting plumbing systems. Many customers reported it worked well to resolve slow drainage and sewer odor issues, and found it easy to install. However, a few customers had issues with the product, such as it not completely solving odor problems or having defective units. Overall, the AAV is a functional product that offers good value, though some higher-quality options may be worth the extra cost for certain applications.

These valves admit air from the room to the drain pipe, allowing for water to drain properly. These are threaded...

Keeney Plastic Air Admittance Valve
Would RecommendThis Air Admittance Valve did the trick on unstopping my kitchen sinks. They now put the water right down the drain and do not back up in the other sink.
