2nd Floor Stack Vent Re-Route

[CPD]

Hello,

I am a first time poster to the site. I am working on a 2nd floor bathroom remodel and have a question pertaining to the re-routing of the main stack vent. Currently the stack has two, 45-degree fittings in order to navigate the vent into the existing wall (left picture). My (current) plan is to shift this wall approximately 12 inches which would require offsetting the stack vent (picture on the right) using 90-degree bends and a short horizontal run. Am I allowed to have a horizontal run in the stack vent at this level? I appreciate the help!

Welcome but no, you can't go horizontal there. Need to be above flood level of vented fixtures (toilet in this case). Also some don't want to see main stack horizontal. (45º counts as vertical)

Thanks for the reply Stuff. I ended up going down the stack and putting in 45s for the offset.
