Are there standard code requirements for taking a plumbing vent out a house wall rather than up through the roof? 1 1/2" PVC.

Thanks!

Your neighbor does not want to smell your sewer.
That was spectacularly unhelpful Killer! :smartass:

I was looking for something more like: "[The] vent has to terminate at least 6" above the roof line. You can run your vent surface mounted, on the outside wall and terminate it above the eave."

That answer came from some random website that I don't trust, so I thought I'd check here. Thanks!

Probably needs to be 3" at some point. Wait for the hack comments to ensue.

What does your code say?

No one here can answer a question without knowing what code you are subject to.

In Chicago a vent has to terminate 12" above the peak of the roof, unless the roof may also serve as a floor, in which case the vent must terminate 7' 6" above the point of penetration, and no vent may exit a building outside the roof.

Your code may vary.

code is different in every State

here in WI it became code legal a few years ago...ive never done it....you wouldn't want it at ground level...you'd want it up high...and if your going up high why not go out the roof.....its supposed to be an option to avoid a AAV.....ive never had a bad AAV when tested and ive never had to replace a AAV......im sure in 20 years i will at some point(they will all wear out)....venting out the side is only to avoid a AAV...just use a AAV and be done with it

Those things aren't even legal here.
