basement plumbing rough in - what are these pipes?
I am finishing my basement (on my own) and am trying to figure out which pipes are which. I'm pretty sure that the "flush" pipe is for the toilet, the small pipe is for the shower drain, the vertical pipe is the vent and drain for the sink but am confused about the other (larger) pipe...
Any help would be much appreciated as I don't want to screw this up and will need to draw up a diagram for the inspection/permit and all that. I'm hoping to put in a tub, toilet, and sink.
Here is a link for pictures:
Thanks in advance for the help,
