I see tons of questions about a 90 being vent only (short sweep), but can't find anything about a 45.
Is there a 45 elbow that's for a vent only, and not drain? In the attached screenshot, I'm wondering if the bottom 2 are for vent only? If not, what's the difference between the top 2 and the bottom 2? It seems the bottom 2 has more glueing surface which I prefer but not sure if I can use it. I'm in Chicago burbs btw.
Thanks all!
