Hello! New poster here!
I am living in a 60s house that has an addition on it (already long done). I am moving the old small bathroom to a space in the addition and making the old bathroom a closet. In that room, I will have a shower, lav, and closet in that order (left to right). I've attached a picture of what I am working with. This is all above a crawlspace. It's worth noting that all DWV piping is BELOW the joists, and no holes are created in the joists for any DVW piping. The closet piping is a little deceiving because of my artistry limitations. The whole closet bit occurs between a pair of joists, I just drew it going right to outline what is happening between the joists.
I have 3 questions regarding this setup:
Thank you in advance!!!

I have 3 questions regarding this setup:
- I am, of course, venting through the roof at the lav, as usual with a 2" pipe. But, since the lav is in the middle of the shower and the toilet, do I need to add an additional vent on either side of the line? I am thinking I probably should add one on the stack side where marked on the image. Could tie that one and the lav vent together in the attic.
- The original house has a basement and the addition is in a crawl space. That being said, to get the waste to the main stack, I have to drill through the concrete wall between the crawl space and the basement, then run the pipe to the main stack which is about 15' away. I will run it along the wall to keep it out of the way. Since the house is a 60s house, the main stack is the old iron pipe setup - meaning there isn't a good way to tie my new lines in. So my question is, is it kosher to use the cleanout at the bottom of the stack to tie in, provided that the very very first thing I do is add a Wye with a cleanout on the wye'd part?
- Aside from the first 2 questions, are there any things in this setup that stand out as wrong, or are there any suggestions on how I can improve this?
Thank you in advance!!!
