    Here in S.F. at least one vent has to be sized no smaller than the lateral [ side sewer ].
    Just curious, Thanks Tool
    We go by the 2006 IRC (International Residential Code). This is allowed by this code. Based on DFU rate, I might add. At first I refused to not run a 3" stack, but finally gave in. I have to compete with the competition.

      In this part of SC, the inspectors say the vent only has to be 1/2 the diameter of the drain line. You see a lot of 1-1/2 vents on houses. I still like to run a 3" when I can.

        It's not uncommon to require a bump in size for cold areas to prevent closing from hoar frost.

            I'm in Minnesota too but way up north, hour north of Duluth. We got lot's of "whore frost" up here!

            Minnesota 3" minimum through the roof. I get lot's of calls for frozen vents and stinky rooms up here. When it gets really cold and the whore frost sets in and the phone rings for a sewer smell I know right away what it is, bring the ladder!
            My house has one single 4" vent for the entire home. I've watched the top of that vent get almost capped over. When it's really cold it's neat to look at everyone's vent and see the steam coming out. You can always tell who just dropped off the Brady's at the pool!
            Only a plumber would notice something like that!!!!!!
