Vent Lines

Author: Negativity Scene (NY)

Skipping the many details that make a 3 inch vent exceedingly difficult anywhere in my barn remodel, I was wondering if I could run three individual 2 inch vents (toilet, bath sink and kitchen sink) and connect them in the "attic" space.

The connections would be made 6 plus feet above the highest floor plane.

Additionally, is it alright to have any slope or bends in the vent lines prior to the connection point in the attic?

Thanks

Author: North Carolina Plumber (NC) Our code changed a few years back, we no longer are required to run a 3" vent on residential homes. I routinely run a 4 or 5 bath home on one 2" vent.
