    Default DWV Layout - Please Review

    Budget overuns on a house my wife and I are renovating are making it neccesary for me to do something I haven't done in a looong time - install a dwv system. Heck, even when I was doing it it was under the watchfull eye of a master!

    The major code where I'm at is the Southern Building Code. Hopefully the attached image of my poorly drawn isometric drawing is understandable. The drawing can also be viewed by following this link DWV Layout

    Although you can't tell it from the isometric, the wyes on the horizontal are on their side.

    Thanks in advance.

    That would work with the UPC code.

    Before I could fully comprehend it, a wise plumber told me... "Go to your vent first."

    Piping in this way will eliminate the unwashed, flat water closet vent.

    I was taught that if you can, head for the water closet first. Doing it that way usually a bathroom can be plumbed and vented off of the lavatory only (as long as the wc isn't flushing past the shower of course).

    Default drains



    All the previous comments are correct. My only addition is that what you call a "Y" is probably a combination Y-1/8 bend from the way they are drawn.
