Plumbing vent through roof
I live in zone 4c. I’m wondering if there is any benefit to putting a 2” 3” reducer on each of my existing 2” vent pipes (there’s 3 total for the house that poke through the roof, all 2”). I have the opportunity now as we’re remodeling to replace all the 2” pipes that go through the roof, the last couple feet or so, and transition them all to their own 3” in the attic and then out through the roof as 3” (or 4”).
My main goal here being to improve my overall plumbing venting and not so much snow/ice buildup because that really has never been an issue around here on our vent pipes. Is doing what I’m suggesting at all going to help improve venting?
