Hi there,
I'm laying out a bathroom sewer, I have a few wyes connecting sewer branches as well as vent branches.
I know that the slope of the run needs to be 1/4"/ft.
My question is, does the branch of the wye need to be turned up (22, 45, 60) and then rolled in the direction of the next fixture (then raising 1/4"/ft)? Like this...
Or does the branch wye just need to continue the same 1/4"/ft, essentially keeping the branches of the wye at the same elevation? Like this...
Also, would the answer be different for a wye that is connecting a vent to a sewer vs a sewer to sewer?
A plumber friend told me I need to have the branch roll up, but I have been unable to find anything in the CA plumber code that specifies that. And my searching of the internet has not given me anything definitive either.
I'm asking because I don't have a whole lot of vertical room between where the sewer exits the building and where the top of the finished floor will be, so every vertical inch counts!
Here's what I'm trying to achieve...
(from top to bottom)
2" Shower vent
2" shower p-trap
3" main (exit on left, clean-out top right)
2" toilet vent
3" toilet
2" lav drain (with 1.5" vent - no pictured)
