Double checking UPC sink vent down the drain line 3 feet

[PlumbHomebody]

I'm double checking my plan to vent a kitchen sink 3 feet down the drain line from the horizontal and then join a branch vent in the ceiling. This has been my plan but then I realized I never see any drawings for kitchen sink venting that isn't come vertical off a sanitary tee... the venting will jon up with the main stack in the ceiling and exit the roof.

Drawing would help. Offhand, I don't think what you describe it code.

Here is a drawing.

An 1.5 trap arm is allowed to travel 42" from the vent to the weir of the trap. A 2" trap arm can travel 60" but you then are required to install a 2" trap as well (tho i've installed plenty of 1.5" traps on 2" trap arms.)

If the wye is within the horizontal distance limits Tuttle mentioned, and within a vertical fall of at most one pipe diameter, the vent takeoff you drew is fine. Except the wye is backwards, you want material that might have backed up into the vent to be directed to the drain.

Good call on the Wye backward Wayne!
