    Default Ipc 2003 handbook - bath group/wet vent

    I'm staring at a picture of a horizontal wet vent figures 9.13 & 9.14 in the 2003 intl plumbing code book - here is a link - i'm 95% sure that is what we uses as of last year sometime. this example is a back-to-back bath group (terminology check?) with a single vent - it looks wet, and it looks horizontal....

    Is it now up to the local code to "allow" this? I have a situation where i'm working close to a joist and would like to keep the plumbing running down one bay - so a vertical vent without a large notch in a joist might be difficult - the lav vent is in the next joist bay, it is back-to-back with a laundry room sink (more kitchen type than slop sink)

    summary: 2" vent - shower t'd into vertical - meets downstream of w.c. at 3x3x2 wye, turned up 45deg. clean-out upstream of w.c. 3" wye. I have room to work - 12" joist, and not much in the way electric-wise - although i may have to work around the hot-water heat loops.

    thanks as alway -

    Default vent

    Because the shower is attached to it, there is little possibility of the vent becoming obstructed and staying that way, which makes it permissable. The lavatory/laundry drain is a bit more complicated than necessary.

    thank you!

    The lav/laundry drain drops into the neighboring joist bay - and just clips
    the top of the joist - knocked out about 1/2 inch - i probably could have turned back into the center of the joist and used it as the vent - but rather than drill it, i just created its own 4' horizontal run - there is also a soffit to hide the vent pipes above - making life easy.

    Was your comment directed at connecting on the horizontal rather than vertical?
