Can a sanitary vent take a jog around an obstacle?
The magic number is:
6&quot; above the flood rim of the highest fixture on the floor served by the vent.
Unless you have a very strange bathroom, that highest flood rim is probably the sink in the bathroom, not the toilet in the bathroom.
Vents are to be &quot;vertical&quot; (which is defined as 45 degrees or more) up to that level, after which they can be diverted &quot;horizontal&quot; (2% slope back to the drain they serve.)
