    Roof venting question
    Is it OK to join two 2" dry vents in my attic using a 3" tee (with 2" reducers). A 3" vent pipe would then be connected to the same 3" tee and exit through the roof.
    I would like to do this solution instead of cutting two separate holes in the roof for the two 2" vents to exit.
    Is this according to code?

    It's called "revent" and is perfectly acceptable. You could revent the entire house through one 3" vent if you eished. Cheers, Tom
