Moving plumbing vent
I am in the middle of remodeling my bathroom which includes taking out a wall. The wall has the plumbing vent running up through it. I just need to move the vent less than 6 inches to run up through the outside wall to the attic. It looks easy enough, but is it OK to put two bends in the vent pipe and have it running up an outside wall?
Thanks in advance, this is something my inspector did not see and I just discovered during demo. |

The offset will be under my sink so I don't think I need to do anything under the sub-floor. What I think I will do is just cut off the pipe as it comes up put the drain for the sinks then above where the drain comes in put a 90 degree to outside wall and up to the attic.
Two questions though, do I need an S trap for each sink? And as long as the vent pipe enters above my last drain I am OK? I will send a drawing of what I am trying to do later today. Thanks for your help. |

You can use a "P"trap for each lavatory or use a continuous waste and just one. You will take the vent off the top of the tee that you stub out of the wall with. You may put as many bends as needed in a dry vent. Just make sure that you slope back to the tee when you run the vent. Good luck, Tom

Thanks for the info. As I thought I could move the vent pipe I conttinued with the demo. As I took out more of the closet wall I now see there is yet another pipe coming from the floor to the vent pipe. This pipe comes up out of the floor in the middle of the bathroom. See my attached picture. I think I am stuck with my abilities now. If I tear up the floor, would it be possible to redirect this under the floor so it is comes up closer to the vent pipe? Can a CPA that knows next to nothing about plumbing complete this task?
I am now just considering calling a plumber to take care of this, but am afraid of how expensive it may be. Thanks for any advice. |

Is there another bath below the one you are remodeling? You might consider cutting into the wall of the room below and put in a 90 elbow or two to get over to the stack. In a pinch I'd consider Teeing this new vent to the other vent in the wall below. Not code but it should work.
