I think my dishwasher ties into my garbage disposal. I think I may put an aav on my kitchen sink and one on another standpipe next to the washer. I just asked the plumbing designer at work and he said they're allowed here. I can't imagine not laying a tee on its back what the fuck do you do then?

Guest, it's time once again for the massively important and exciting FoH Asshat Tournament!
Go here and give us your nominations!Who's been the biggest Asshat in the last year? Give us your worst ones!
And don't for a second think just because I work at an aec firm I care about anyone advice besides what I hear on rerolled.

You're supposed to use a Y and a 45. You're also only supposed to use 90's on drainage when going from horizontal to vertical, not vertical to horizontal or horizontal to horizontal. All about getting some smooth flow through them pipes. Venting you can do whatever the fuck, it's just air going through there.
As far as your dishwasher tieing in to your garbage disposal goes, that's fine.
AAV's are cool so long as they're okay by code. Some codes say they're only kosher in certain situations like renos/retros or if a sink would otherwise have to be island vented:

I definitely didn't until I started reading all these god damn codes. I liked it better when I was just hooking shit together until it went where I need it
Thought you 'mericans (Canada is in America!) had the traps all down by the floor, oh well, the more you know!
Big E if you can dream it i can do it.
Except my over 4" flange isn't going work because it's about an inch above the concrete.
And i'm kinda worried about not having a vent on my floor drain but my hands is tied.
I really fucked myself by not thinking whether i needed street or regula elbows today.

No, having the trap significantly below the fixture drain makes it much more likely for the water's momentum to pull the trap seal.
Right, makes sense. I thought I saw it in some pics at work of the American version of the sinks I'm selling, but yeah, probably wrong
Picasso?

Floor drains aren't as big of a deal for venting. By code up here, if they're 3" or 4" p-traps and only for "emergency use" (don't see much use at all), so long as they tie in to a vented drain within the "fall" of the pipe diameter, they're fine. So at 2% grade with 3" pipe you're good for 12' or 16' with 4" @ 2%. You also can't have them too close to the branch, but if it's a few feet you're good.
The thinking there is that the drain is only going to rarely see flow, so it won't get pulled by it's own momentum. And water rushing past in the branch or main it's tied in to is far enough away from the larger 3" or 4" trap that it's unlikely to siphon the seal off, as the branch is vented elsewhere anyways.
Busted out my code:
"A trap that serves a floor drain need not be protected where:
a) the size of the trap is not less than 3in
b) the length of the fixture drain is not less than 450mm and
c) the fall on the fixture drain does not exceed it's size"
And yes, the Canadian plumbing code happily mixes imperial and metric measurements for the fuck of it.

I have a hell of a slope on that branch right now because it comes into the house that way. Hopefully it'll flex enough to flatten out a bit.
