I am finishing a powder room (sink and toilet only) that already has the piping in the ground for the toilet and right behind the toilet coming up the wall is a 2" line coming up about 4 feet and its capped off.
I am assuming that this 2" PVC behind the toilet is for venting AND for my sink drain? So I am thinking that I would connect the sink drain to it using a Sanitary Tee for the waste to go down and going up the Tee would be a connection to a Studor Vent.
Is this how I should be planning this?
If so, what size would I use for the actual sink drain? (1.5")
NOTE: that 2" pvc coming out of the ground has no where to go up through the first and second floor on out to the roof like a normal vent.
