Studor Vent in bathroom remodel

[Jsmallberries]

Bathroom remodel, ceiling opened and a plumbing vent stack has a "jog", so it can go around some framing and would be blocking the open ceiling plan. Big box recommended a Studor type vent as a solution. Just want to see what you all say about that.

Any solutions recommended?

The pipe on the left is for the washing machine. This is in a bathroom with a shower, toilet and sink. house vented w/standard roof vent stacks

Are you asking where or how to mount the AAV? It must remain accessible and vented. AAV must be at least 4 inches above the trap arm. You could jog the AAV to the left with a pair of 45 bends.

Where does the vent go above the offending jog around the beam?

If you want to remove that dry vent, you'd need to follow it up to where it connects to another vent, and remove that connection. You can't just cut the vent and put a cap on it. If, for example, the vent went straight up through the roof, and you just cut it and cap it, it will fill up with rainwater over time.

Your best bet is likely to figure out how to modify your ceiling plan to allow boxing in the existing vent without modifying it.

Modification of plan might be best.

There might be other fixtures attached. Guess I could cap the roof vent and see which fixtures don't flow. The AAV would be inside the wall. or in the attic. Can they be any height over the trap?? What other cons are there?
Thanks

If this plumbing vent stack connects to the washing machine, shower and sink but not the toilet, would that work? (Not allowed for commode, right?)
I could install it min 4 “ above trap arm, vented and accessible from the other side which is laundry room

Depends on how they are connected. I suggest you post a diagram of what connects to what.

It's slab on grade, how would I tell that now?

Would my idea of temporarily blocking vent at the roof, to see which fixtures don't drain?

Was this a hypothetical question, or is it related to what you think is going on?

You are not allowed to use the drainage from a laundry standpipe to vent a shower or sink. Why did you bring up shower and sink?

Here is the deal: if you are asking how to replace the vent pipe shown in your photo, it is very easy.

If you are asking how to use that pipe going into the slab to also vent shower or sink, that was not allowed with a vent thru roof, and would not be allowed with an AAV.

No. Bad venting does not cause non-draining.

Why not just build a wall in front of the existing wall to cover the vent pipe? Or just jog the top of the wall around the pipe? Silly to go to a mechanical vent instead of the best option for something like this.

No. Bad venting does not cause non-draining.

A Studor vent (AAV) can work as a solution if it’s allowed by your local plumbing code and remains accessible for inspection. It’s designed to let air in to balance pressure but doesn’t vent gases outside, so you still need at least one main roof vent in the system. If possible, a better long-term fix is to reroute the vent with 45° fittings to clear the framing while keeping it tied into the main vent stack. That keeps it fully vented and maintenance-free. In short: Studor vent = okay if code allows; rerouting the pipe = best practice.

AAV is as common as Aligators in florida
