Basement Plumbing Layout (New York Code)

[Katehis24]

Hey guys, I'm redoing the plumbing in the basement bathroom since it was never vented properly. I cut all the existing pipes out. I re-connected a new 3-inch pvc into the existing 3 in pvc that led to the stack that goes to the street.

I would like to know if everything is up to code for NY, specifically Long Island. Nothing is glued yet, and the pitch of the pipes is already close to the 1/4" per foot.
