I would like to relocate a vent line so I can move a bathroom sink to the center of the counter instead of near one end where the builder located it. If you look at the attached photo, my plan would be to cut the left-hand 2" PVC pipe (the vent) a few inches above the bottom plate, use a 90 degree elbow to run it to the next joist space over, then add another 90 degree elbow to go straight up through the top plate. I'd replace the existing drain stub tee with a tee pointing to the left, through the stud, then out through the wall with a 90 degree elbow. The red lines show the proposed drain/vent piping runs.
The vent lines in the attic above are easily accessible and run along the rear of the house (behind you, when looking into the photo). There should be no problem making the connections there.
If it matters, the vent (left-hand pipe) runs from the laundry room below this bathroom, where the washing machine drain box and the drain from this bathroom (right-hand pipe) tie into the vent with a double tee (is that the correct term for an "X"-shaped tee?). The shower (behind you when looking into the picture) ties into the right-hand pipe just below the subfloor; there's a separate vent line for the shower that ties into the vent running inside the ceiling joists above.
The ceiling joists tie into the main beam that runs from right to left in the ceiling behind this wall (you can see the column that holds up that beam if you look through the second from the right stud space). I'm not sure that I'd call the wet wall here load-bearing, but do I need to double up the 2x4 that I'll drill in three places to accommodate the new drain/vent runs? (Obviously I'll run the 1/2-inch copper supply lines through that stud as well.)
Is there a better way to accomplish this, without running drains inside the cabinets? I'll be removing the sheet rock from the wet wall to add a pair of sconce lighting fixtures so the entire wall will be accessible.
Thanks,
Tony
