Top Air Admittance Valves Best Test Reviews

Here at the NYCC-mag, we like to think of ourselves as crazy (in the good way) about the stuff we buy, but as much as we’d like to, we can’t try everything. Which is why we have independent tests in which we find the best-reviewed (that’s testing reviews, and lots of ’em) products and single out the most convincing ones. While we’ve written before about the best air admittance valves, a virtually indestructible AAV, and the best plumbing vent alternative, here we’ve rounded up the best-reviewed air admittance valves testings. (Note that test reviews have been edited for length and clarity.)
