Hello, I have a general question about DWV fittings: is there any code requirement for distance between two DWV fittings other than specific situations like trap arms, etc? Like if I have combo, wye and 45 fitting that need to bump right up against eachother due to space constraints is that ok? Or does there need to be some amount of visible pipe between them to pass inspection?
I've looked through the local code book but can't seem to find the answer to this question.
I also have a specific example I'm wondering about: I'm trying to fit a closet elbow into an 8" joist cavity and I'm wondering what the quickest way to make that turn is. I have two things in mind...see the attached photo. Option 1, which I've seen suggested on here before, is a 4x3 spigot/hub elbow with a 4" flange on top. But I'm also wondering if option 2 is a valid/not-dumb idea. It's a standard closet elbow, with a very small bit of 4" pipe, and a flange sitting inside of that.
I haven't seen option 2 suggested on here, so I'm assuming it violates something or doesn't work well in practice, but I'd like to hear from those with experience.
Thank you!
