Hi, been lurking for a while, working on a little project that needs to be up to code. Can someone check my layout and make sure I'm not messing anything up? This plumbing will be installed underground, all horizontal, it's not new construction so I have limited space and the clay beneath the concrete is hard as hell.
Here's my diagram - http://imgur.com/7nqnSIJ
I didn't draw in the vents, since it would have just cluttered up the drawing, and I'm pretty comfortable with those. Basically I have a line of plumbing that starts with a laundry hook-up, then a mop sink, followed by 2 showers inline and finally a toilet and vanity right before the sewer hook-up. whole run is about 38' or so. I know it needs to slope about 1/4" per foot, and I know about the vents.
Questions are as follows

Questions are as follows
- Is it necessary to run a 3" pipe for the whole run, even though the toilet is at the very end of the run (last item) or would 2" suffice?
- Am I using the Wyes properly? I didn't initially realize all the Wye's/tees/sanitary tees all have very specific uses.
- is it ok to run the toilet directly above the pipe and just connect straight down with the wye? (shown in the section drawing labeled 'A'
