sink vent

[horzman]

Hi all,

building a house, the plumber disapeared after he was paid in full, I made the mistake of paying him before passing rough-in inspection, now I'm stuck with finishing what he didn't finish. he told me he was done and up to code and ready fo inspection, but when inspector came in, I ended up with a big list of things to be fixed. Plumber of course no where to be found.
finally I passed rough in, now ready for drywall.

My question, the kitchen sink and a bathroom sink have an open floor above so he couldn't run vents up to roof, instead he has about 7 feet of 2" pipe caped.... now what do I do with that?
there is no way to run vent pipes up... can someone please advice.

Thank you.

Run them horizontal to a stud wall, then up and out, or build a pipe chase.

it's almost impossible to make such a run.... what is a pipe chase?

A buildout from the wall that conceals the piping.


Also, how did the inspector pass a DWV system that wasn't fully developed through to the roof where it should penetrate?

Sounds like the inspector is as bad as the plumber. What state are you in?

NC, the plumber told me that, it is a common practice when they cannot run the vent all the way up to do that.
the inspector did not seem to have a problem with it.
I just don't know what to do with it, am I suppose to cut the cap off, and install an AAV?
Thanks.

The architect or builder needs their head kicked in, designing a house without a wet wall.

Hi again,
this morning I went under the house to see the way the plumber ran the pipes. it seem that from the ventless sink down to crawlspace 2" pipe then ran about 15feet horizontally with a slight drop then where this 2"pipe meets 3" there is a Y 2-3" that connects to the dump into the main sewer and 1-2" that branches up 45 Degrees then through a wall then all the way up to roof.
is this what call wet vent?
Thank you.
