In response to Re: vents
There could also be a big difference between what it says and your interpretation of it. I doubt that any code would allow a 1 1/2" vent to be the main, or only, vent.

: I think your reply has to do with UPC not IPC requirements. Again I've done some research on web and think that a bathroom group can be put on a single wet vent that uses one dry vent at LAV. My updated thinking would be to take a 3inch wet vent which would handle 12 fixture units and drain all bathroom fixtures to it. At the end of the run where the LAV is I would extend the vent through the roof as a 1.5 inch dry vent. There appearently is a big diffenence between the UPC and IPC venting requriements.
