I spec these for island sinks and other spots where it would be hard to run a vent. Once I specified these at an exterior wall that had a steel beam above that didn't allow a vent to go by it. To make things more interesting, the architect had called for a clear glass counter top. I specified that the AAV be placed in a vented wall box located on the exterior. That got the AAV out from under that glass counter. These units save a lot of labor and therefore save the client a lot of money.

@deezynar Hey deezy;

That sounds like quite a little project for sure! I am a fan of them as they are allowed in Canada under certain circumstances. The code here allows this just for certain applications. I have used them and they do work very well.

Thanks for commenting and enjoy 2012! Al

under no circumstances would I ever put an automatic air vent in any kind of system. You mention island sinks, why not back vent and run a 2 inch line to the island sink with a glued (no union) p-trap like we do in Canada. if your spending 5 to 30,000 on a kitchen reno and your worried about breaking a few holes, blah blah blah, what about rusting the spring shut and or open. They work great for about a month. I can't tell you how many I have ripped out because of stupid installations

@educatedrock hello;

Everyone has there own way of doing things for sure, but in Canada the plumbing code states that you can use this in an island in a kitchen. As far as them working for any length of time; they work very well for many years with no trouble. I would say the plumbing code of Canada would not allow them if they didn't.

Thanks for your comments and have a great day!!!  Al

@melavey Hello there;

This vent is called a V200 as you probably know and in this part of the country; the inspector approves this style.

It all depends on the jurisdiction as to approval or not. Many different companies make these valves such as Moen and Oatey and they have changed the valve cover basically as well, but they all do the same thing in the job.

Thanks for commenting and have a great day!!! Al

in canada that is called a cheater vent ,because of the 2 large holes and rubber diaghram it is not approved if being inspected , and what we call an auto air admittance valve will have several small openings around the whole dia and will have a diaghram that is made out of a siliconized rubber which will never dry out , while both do the same thing the A A A valve is far superior add would be approved if inspected and no other option is available . see canplas plastics for their A A A valve .
