Rated 4.5 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by Big help for installing utility sink in basement The air admittance valve makes it relatively easy to install a new sink in an existing structure by making it unnecessary to find or add a vent line. This unit is well made, and the instructions are clear and concise. It fits either a 1-1/2 inch or 2 inch drain pipe, which will cover most installations. March 30, 2014
Rated 5.0 out of 5.0 by Performed as advertised!! The vent was very easy to install even under the sink where it was needed. I was skeptical at first if the vent would fix the drain problem I was having, but after the installation the problem was gone. November 4, 2014
Rated 3.0 out of 5.0 by Sure Vent The vent still seems to allow sewer smell back into the under-sink space. August 11, 2015
Rated 5.0 out of 5.0 by Great for gurgle and drainage issues This is a great product for resolving suction issue that can end up letting sewer gas back into house. Used this in my kitchen where the old cast iron vent rusted in wall. This was a quick resolution for fixing a gurgling sound and slow drainage in kitchen sink. I would recommend to anyone who doesn't want to tear into existing walls to repair or install a vent stack. April 26, 2015
