I am installing a floating vanity and need to move a 1 1/2 vent line behind the wall. I am in a row townhouse.
How do I run the 1 1/2 pipe around the corner? Do I cut a hole in the studs or notch them?
One side has a 2x6 the other side has a 2x4.
The side with the 2x6 is an exterior wall and side with 2x4 is adjoining with another townhouse.
In the picture I included the new routing of the pipe.
