Hi! New guy here. There seem to be plenty of experts on this forum, and I'm hoping I can get a review on my DWV for a new house I'm building. I'm way past DYI; I'll tackle anything. I have 3 books on plumbing, and they all seem to differ. The local inspectors just give things a quick glance, so I'm more worried about having a properly operating system than passing inspection. I did a crude sketch, then assembled it dry-fit to see how it's all going to go together. I attached the sketch and a couple pics which give a 3D perspective. A few points:
Every fixture is on its own branch and has its own vent, which will then tie together in the attic.
This is for a master bath and a powder room in a one BR house.
The main branch is 3"; the smaller branches and all vents are 2".
The whole thing drops into the basement through a sanitary T (horizontal to vertical).
This main stack goes up through the attic as the main vent.
There is a bathroom in the basement (below the powder room) which was plumbed by a licensed plumber, so I assume (!) it's right.
The little arrows on the sketch represent clean-outs.
The main branch will be below the floor joists. I connected the 2" branches with a Y+1/8 rolled up on a 45 degree angle to tuck the 2" stuff up between the joists.
I have a few questions, but first let's see if I'm in the right ballpark with this thing. I already know all of the basics, such as pitch on the horizontal runs, and which kind of fittings are allowed where. I'm more concerned about the function of the whole system.
