    December 8, 2019
    Is the T portion that comes off at a 45 to the right in the picture the 3€ part? Or is the 3€ portion at the bottom?
    1 Answer
    The top and bottom of this wye are for a 4" diameter Metal Fab type B gas vent pipe, while the branch (at 45-degrees in this photo) is for a 3" diameter.
