I am putting in a sink. The drain line is under the sink (in concrete), not in the wall behind the sink. The wall is open for me to run the vent.
Is the best way to do this as follows:
come out of trap and run into the wall like you normally would. In the wall would be a sanitee, vent going up and drain going down. then, 90 back out of the wall toward the drain pipe. Connect to it with a sanitee with a cleanout on top?
Is there some better way?

yes. Like that.....
One question. If I kept the drain piping under the sink and had a sanitee on its back rolled to 45*, vent running on the 45* up and into the wall, then Another 45* to get me vertical. Would that be ok? I can do it either way.

Hey Terry, yes a drawing or pic would help I'm sure. I'm a terrible artist... LOL
Essentially, I need to run it on its back because I don't have the vertical height remaining to get to the drain as there is a cleanout on a T coming up out of the floor. I don't want to try and take it off and risk cracking the pipe, then digging up the concrete.
