drain
I would not even try to describe how to do it, and if you use the picture, make sure you do it EXACTLY as shown, even though you might think that some of it is not necessary, or it looks like a shortcut might make it easier.

There are several ways to install a bow vent.
My code book allows 1-1/2" drains with 1-1/4" vents BUT, I would suggest going with 2" all around.
The drain is connected to a vertical stack below the vent.
There cannot be anything draining above the vent in that stack, both are connected as if they are both drains...use the assumption that the vent will be a drain.
If any of this is unclear, I'd suggest having it done by a plumber, once that slab is repoured - it's all over but the cryin'.
