    Hi experts,

    I'm installing a new sink in an addition and I could just use a double check on my DWV fittings.
    Thanks!

    Ok, I can't attach my drawing so I'll have to summarize....

    DRAIN:
    Sanitary tee to connect the P-Trap(Horiz), the vent(Vert up), and the drain(Vert down).
    90 degree sweep elbows for vertical to horizontal drain turns.
    90 degree sweep elbows for horizontal to horizontal drain turns.
    45 degree elbow for horizontal to horizontal drain turns.
    45 degree wye to tie in the new horizontal drain with an existing horizontal drain

    VENT:
    How do I tie in the new vent(runs horizontal) to the existing vent(runs horizontal) in the attic? Do I just use a short tee?

    If you are tying into a vent only you can use just about anything; if you use drain type fittings make sure that they are run with the flow toward the vent.
