These are not great pictures sorry so Ill try and give as much information as possible here. I'm an electrician by trade doing some plumbing in walkout addition that was added sometime before I purchased this place. Concrete floor was never poured a few sections of concrete were in there which I removed. Anyway what we have here is 4 inch sewer line that goes through corner of this part of the house and out to septic tank. It comes out of basement which is next to this room then when this part was built they built over it. So few questions any info is appreciated. I included a really crappy sketch so here we go. I'm thinking add a 4x4x3 wye then 3 inch 45. Now the pipe would be plumb vertically and then use a double elbow or combo tee wye to branch to the toilet and over to the lav and part way to the lav wye off to the shower drain , and using the lav to wet vent this area, maybe I also need a shower vent in this situation? The other thing is does all this piping need to stay deeper then that ? If this is crap let me know again any info is appreciated. The strings hanging in the pictures are about locations of the stub ups I'm going to attach a plumb bob when setting pipe at right location. ok thanks
