If you do this, you will be in the good books with any Canadian inspector and or Canadian juresdiction. Your sizing of venting and dranage is ok. We generally do not use any 1 1/4" pipe and fittings any more because they are double and triple the money than the 1 1/2". (just a cost factor)
You are allowed to use 1 1/2" for your bathtub drain. 2" is optional. The waste and overflow assembly kit for the bathtub will be 1 1/2" anyway

The sketch Krow made is in line with what I was suggesting. I would however, break out some more slab and run the lav drain more direct with fewer elbows and shorter horizontal runs. Both have effects on reliability. 2" is a minimum Dia. under the slab.
As with anything there are a few different ways of doing it. Below is a sketch of what I was saying. I did not show connection details you seem to have a handle on that. Please excuse my rudimentary drawing... What did your program cost? Where is it available?

If you want to stick with the pic I provided, maybe these slight amendments might suit you better
Thanks for all your input Redwood - I believe I referenced you to krow in one of Krows postings you have both been v helpful/useful and patient with my lack of knowledge - so thanks again
SOFTWARE TITLE: 3ds max
Price: 3K+ tax depends on what version you buy.
You can download a free trial but if you've not done any 3d before, it prob going to be more work than results - that said i picked it up ok so im sure anyone else can too
Im up for doing visuals if you need any (which i doubt) but the offers there - just let me know.
I don't have the software but I could do you some visuals if you needed!?

At this juncture, I believe the last image to be complete and final - thanks mainly to Redwood, Krow, Mikey & Jimbo + everyone else too.
If anyone has any questions let me know - once again, a big thanks to you all.
I guess I'll keep the rough ones I'm using...
That last sketch should do well for you!
It certainly looks a lot simplier than the one you started with huh?
a2) yes, if the upper floors aren't vented properly.
Here's a simple test I just made up, which a real pro can correct and my feelings won't be hurt: for any fixture, its trap must be vented, and that vent path to open air cannot be affected by anything that can suck or blow. There are special cases (e.g., stack venting) that aren't obvious.

novicepiper - peace
ok - sorry about this how would I vent the kitchen sink or is it already vented in the main stack? ( going on what i think i have learnt thus far and this willl be really painful for me if im wrong) if the main stack acts as a vent for the kitchen sink will discharge above cause it to siphon the trap or push bubbles through the trap - i guess maybe i should tie it in above the 2nd floor toilet or does it just have to be above the kitchen sink in the main stack?
I did a quick repair on the soil stack (CAST IRON) the other day - this is how this all started out - i replaced 4 ft of cracked stack in the basement and replaced it with ABS 4" I tied the waste into the stack and vented by accident to the 2 inch vent seperate to the stack and now when i flush the toilet on the second floor - there is a heavy thump from below when its about half way down the flush - there are no weird smells or anything it's just really loud when your in the bathroom. like a mini earthquake - any hows, enough of the blah blah - basically i just could do with a quick answer of how, what and where i tie the kitchen sink in re vent - the actual waste will be joing into the 4" stack as per agreed visual earlier - once someone answers this i think im good for the preposal and maybe start it soon
Holy crap - im all typed out now. - that was painful

The kitchen sink is probably vented by its own vent and not the stack. Or, tied into the stack above all the drains.
anyhows it sort of made sense to me to vent the sink obove evrything else on that stack. that was also based on mikey's cool explanation too.
thanks for that redwood.
