 air admittance valve
Author: gigisabi (CT)

I have a emanating "rotten egg" sewer smell coming from under my kitchen sink. I believe theres a problem with the air admittance valve located under the kitchen sink. I thought that you can only use an AAV for plumbing an island sink. Is this to plumbing code (AAV) for the state of Connecticut.

Probably is legal unless local code prohibits their use, replace the AAV with a Studor brand valve, see if the odor dissipates.

Can you post a picture of the kitchen sink drain piping?

www.photobucket.com or similar then provide a link to it here.

Oatley makes a good AAV. Pricey, but worth it.

GOOD and AAV in the same sentence? I didn't think it was possible.

How old is this AAV? They are mechanical devices and are going to wear out! I am an old school plumber and believe that traditional venting should be required in all new and major remodeling work, period! However, I also believe that AAV's have there place in minor repair & remodeling work e.g. replacing an S-trap with a P-trap, on existing fixtures where no vent was before, etc. "Something is better than nothing!!!" Look into the Oatey AAV, or another heavy duty one(like anything else, you get what you pay for!), as recommended by another poster. In your case, the cost of opening walls and running a vent just for the sake of installing one can't be justified. However, if you ever do a major kitchen remodel!

I would see what it would take to put in a loop vent. It might be possible to pick up a vent if the sink was elsewhere before the island sink. AAV's are a vent of last resort because they stink.

He knows that because it was the reason he was posting the question.

I've had a few problems with both Oatey and Studor. I doubt that those old black ones that come on mobile homes and sell for about a buck would be any worse. ( I can't believe I'm suggesting a non-code approved device)

My home was completed this year (April 2006). I moved into this NEWLY built home May 2006. So I'm assuming it's an issue with the builder and plumber. The smell "REEKS" soooo bad. I called Town Hall and they will be sending a plumbing inspector to see if it's to code...Thank you

This type of info should be in the ORIGINAL post.

It's not your problem, (except for the unfortunate smell of course), let the Builder & Plumber deal with it and it appears that they are not if you had to resort to contacting the Building Department.

Good Luck.
