: What can happen is if there's a clog in the line, the clog or part of the clog can possibly move behind where to toilet drain ties into the horizontal line, the clog will be cleared by snaking the line from the toilet drain. Something can stay stuck in the vent fitting. Then you'll have a toilet with an inoperable vent.

What if 2 sinks would drain in directly behind the vent
