I'm doing some remodeling which requires removal of an interior wall that contains a 3" drain line. My plan is to reroute the drain down the adjacent perpendicular wall. Due to space constraints around the wall being removed, I'll have to replumb and move much of the plumbing over one floor joist.
I've come up with a solution that I think will work, but I'm just a DIYer with no major plumbing experience like this. I would appreciate feedback on my plan to see if it looks like it's to code (IPC) or if I've overlooked anything.
Here's the current layout:
And here's my proposed layout:

And here's my proposed layout:
- Move the tub drain so it connects further upstream on the 2" drain. This will reduce the number of holes I need to put through the floor joist.
- Continue the 2" drain though the joist, then elbow turn parallel to the joist.
- To avoid cutting in the middle 1/3 of the joist, bring the 2" shower trap arm further down and then through the joist.
- Join the 2" shower line to the drain and increase drain diameter to 3" to accommodate additional dfu load.
- Use a joist reinforcement plate to allow cutting of hole through floor joist for the toilet.
- Toilet connects, using a long sweep elbow, to the main inlet of a 3x3x3 wye with 1/8 bend.
- The 3" drain line carrying lavs, tub, and shower connects to the side inlet of the wye.
- Outlet of the wye connects to an elbow and down the wall.
