revised layout so I wouldn't have to remove stairs for plumbing. Hopefully I am far enough away from the footing for the column at the end of the stairs. Also fewer bends on the main 4" branch.

Lets try this again. This time I am leaving the kitchen/floor/laundry drain alone and connecting the new bathroom pluming to the 4" CI from the bathroom at the front of the house. There is a lot more distance to travel (cutting through ex. slab) but I believe it makes the plumbing a bit more...

Then is the water closet not properly vented either? This is why the original layout had the drain going to the back wall to vent the WC and connect the lav. Should I go back towards that layout?

moved shower vent to new 2" vent.

Revised ISO with distances. Let me know if there is anything glaring... I think I have too many fixtures on the existing 1.5" vent (washer, kitchen sink, utility sink, shower, floor drain)

I will try to add detail to the layout to show lengths. Might have time tonight. The work will be permitted I am trying to find a solution to the plumbing to get the permit... Good idea about adding the cleanout.

Didn't think I should put PVC/ABS beneath the foundation. Is ABS allowed beneath a footing?

Any thoughts or suggestions on the revised layout above?

connection I spent the afternoon digging a hole to confirm the connection point. The 2" comes out of the house and connects to the 4" concrete pipe about 2 feet from the foundation wall. You can see the 4" connects via a wye, the upstream end is a roof downspout from NW corner of the house...

Revised Layout Here is a revised layout 3 inch from the water closet straight out to the drain connection outside. WC wet vented through 2" Lav connection - route vent through roof via soffit, joist bay, main floor wall cavity, attic. Utility sink connection moved above the drain line to vent...

Thanks for the feedback, I will work up another layout to post Thanks for the feedback cacher_chick and dlarrivee. I will take your recommendations and revise my layout, just haven't had time to work on it yet. I will have to put the vent in a soffit to run to a first floor wall cavity where I...

First attempt at layout Haven't received any feedback so here is my first attempt at a layout. Concerns/questions 1. Can an AAV be placed in a wall cavity? where do these usually go? 2. Is there sufficient venting for the shower between the 1-1/2" and 2" AAV? 3. Can the drain and vent for the...

Quick background details, House was built in 1952 with unfinished basement, concrete all the way up to the first floor sills. The main floor bathroom has a 4" cast iron stack that leads out the front of the house, away from the proposed bathroom location and is approximately 20" below finished...
