Tommy Mac gives a good reference but I'm pretty sure in most jurisdictions you'll have to have a minimu 4" vent or combination of vents equal in area if you have a 4" main drain.
*b 4" drains for homes....who'd a thunk it.What's the future hold with low cost fuels, boomers at their peak earnings, Xers starting more internet million dollar sites than we'll ever have time to visit.....b 6" drains, personal aircraft carriers, a rush to stake out planets!!!!Maybe?Jack : )

I REALLY want to know how old Jack is??
*the vent stack shall be the same area as the building drain which is the pipe going out from the house and stopping 2 foot from house. 4" is 12.575area sq in you have to equal this or better.

I have recieved several opinion on whether to install a 3" or 4" vent stack. I have a 4" building drain and 26 fixture units on the system. Only one vent stack to which everything ties into. The UPC says to have as much aggregate vent area as building drain, but is this the installed drain or the required drain size? A 3" vent would be easier to install (less framing cutout and no chase to construct), but if 4" is the way to go then so be it. Any ideas on this one? Thanks.
