Hey Again,
Sorry for the multiple posts...I work best keeping things separate.
the laundry room shares a wet wall with the bath, but is 3 feet higher than the floor of the bath.
I can finagle the laundry's 2 inch discharge line behind the tub surround on the drain side.
Can I simply connect this to the tubs drain line (after the tub's trap) with a Y connector, and importantly, can I then rely on the vent stack as the laundry vent.
I could, if required, run a 2 inch line parallel to the tubs drain line, but it seems like it's overkill.
As the crow flies, the 3 inch main vent will be about 6 feet away from the laundry down tub.

From YOUR description, I doubt that the tub vent could EVER be a vent for the laundry, and it should NOT connect between the tub trap and ITS vent.

Thanks...I guess I am going to need to do some re configuring to make it work property.

If you could post some photos of this project it would help to understand what you have and likely make it easier to get good advice. There may be some criticism, that goes with the territory but don't let it discourage you. Anyone that's been following your posts knows that you are not under any code or inspection requirements, you just want it to work and are trying to avoid doing something that causes a plumbing problem later.

You guys have been awesome!!!
Here, in theory, is a sketch of the whole shebang.
[i1244.photobucket.com]
The red is the 4 inch waste line. leading to the septic tank.
The kitchen sink can essentially go out the wall and connect there, and I can get a vent line up that wall (and enclose the exposed pipe)
My theory is to build a 3 inch vent stack OUTSIDE the structure, right as it seems to curve in towards the toilet. Again, structure can be built.
Toilet connection is easy.
I can connect the sink to the waste line, very close to where the toilet will attach, and the same goes for the tub, both 1.5 inch lines. Sink vent is easy as well.
If that's OK, then that leaves me with the laundry line, both vent and wet.
Can I use the 3 inch vent stack to take the discharge (sounds bad as I type it) or do I need to fit that into the waste line inside the structure?
If I do put it into the waste line, it will hit that line literally a foot from the main 3 inch vent stack - would I need additional venting?
You guys are the best...so part of the story is that this is for my mother in law, who has twice lost her home to fire. I am doing this out of pocket, and frankly, money is getting very, very tight and your help has been invaluable.

I'd consider running the laundry drain to the nearest 3" drain line. If you can't easily add a vent pipe for the laundry drain you could install an AAV, it will let air into the drain when needed. Are you planning to use a standpipe behind the washing machine for it to drain into? Washing machines work better if their discharge hose is not directly attached to a drain pipe, there needs to be something like an air gap, that's why a standpipe is typically used, otherwise you can get a siphon going and drain the WM when you don't want to. You can also have the WM discharge hose empty into a deep sink (laundry sink) and then the sink can drain at its leisure into a smaller drain, even a 1-1/2" drain would be fine. Many laundry setups use a tub or sink for the washer to empty into when a larger drain line isn't available or feasible.

Thanks for fixing my pic...I am technologically challenges (I still have a flip phone).
I Will have a stand pipe, no problem...I can make this a standard height, including keeping the trap elevated.
All 2 inch.
It looks to me like there will be a cluster in the corner, when the tub, sink and now the laundry all connect to the 4 inch main line.
This area where I have cut through the concrete slab is small---maybe 16 inches by 2 feet.
Can I connect the the tub and laundry with a Y?
Are there any spacing issues I should know for making these 3 connections, or is it OK to get them as close as i can to each other?
Any advice on those connections?

Here is how I would do it. This does not show the drain for the kitchen sink, but that would be downstream from the laundry connection on the main. Just a suggestion...

Thanks for all the help!
The help I got here was invaluable, and your pic was great - very helpful.
It all came together wonderfully, and I was actually able to get the entire thing done in one day.
Thanks again.
