Gable vent for DWV vent termination?

[Nate R]

I seem to recall reading somewhere that there are gable vents available to connect to a plumbing vent to allow exterior termination (As opposed to an AAV) without going through the roofline. But I can't find anything online like this. Am I making it up, or does someone make a way to terminate a vent through a gable? I have a main stack that's CI, but the easiest route to vent my new tub and sink would be through the gable, if possible.

No one? Is vent termination through a gable allowed at all?

Under some lenient codes it may be. Through the roof would be better!

If you think about what comes out of that vent, you wouldn't want it anywhere but as high as you can get it. Depending on the wind conditions, location of windows, etc., you could end up with it blowing into your bedroom, or infiltrating the attic through other vents. It is specified to be through the roof for a safety, practical, and health reason.

Usually, if you vent through the gable or the side of the house, you are required to run the vent above the roof anyway. (UPC)

Same under IRC.

Gotcha. Well scratch that then.

I guess I wasn't really thinking about what comes out of there. I keep just imagining venting as a pressure balance mechanism, but it's much more than that.

The vent is an open line to the sewer or septic system.

Right, and I wasn't thinking of it that way when I was thinking of gable termination.
