Anatomy of Sink Drain
For space efficiency - p-trap goes straight back
3 main sections of sink drain are tailpiece, tailpiece extension, and p-trap.
With a dishwasher - we also have a dishwasher tee
Here we show p-trap going to the side for easy disassembly - but it is fine to go straight back to save space under sink.
We can easily drop the p-trap lower, so we can locate the drain pipe in the utility channel. Otherwise there are 2 sheathing penetrations: suppy and drain
(We must go back to version with lower drain pipe)
3-3-2” wye
Before
Rough Plumbing Penetrations Go Through ‘Utility Channel’ Area of Beadboard
Note where plywood ends. This allows water penetrations to happen easily. But we could avoid cutting the plywood. Can we just drop the drain lower? The highlighted trap is 20” below sink drain.
Washer drain needs to ‘empty’ into 3” drain. But what is maximum ‘run’ allowed before it empties? Is that determined by location of vent? If so, this pipe should be 3”.
This would take cabinet space. If a flexible p-trap is used, we can create cabinet space as we can place trap at bottom corner of cabinet.
But since this we lowered the plumbing pipe down to make penetration in ‘utility channel’ area of the beadboard - so we panetrate a small, more maneouverable piece of beadboard: remove beadboard to make cuts to not damage pipes.

So move the orange forward so that 1st floor drain goes straight into it without a turn

Moving the stack forward allows simplification of shower so valve mounting is identical on both floors (31.5” to stall flange)
Note that these 2 must be ¾” each to provide the required flow

Vent
Questions
Explained for highrises. This is a special case?
Stack vent is the extension of stack to provide venting.
What is a combination waste and vent? Horizontal wet vent + up to 8’ wet vent riser. But went vent upstairs can’t have blackwater.
The Single Stack Vent System involves an oversized stack and oversized drain verticals. It limits the distance of fixtures from stack - to 8’ for toilet and 12’ for others, requires 2” vertical drains, and no more than 4 feet drop from fixture to branch drain. When these conditions are met, then we can use a single stack. Most houses probably don’t do this because their plumbing is spread out all over the place - and is a case where effective design is actually endorsed in codes. This thread supports this reason for why single stacks are not common.

Revisiting the Waste Stack Vent
Do I need a separate vent? P. 11
What is a single stack vent system? P. 17
Uses oversized stack. The length of trap arms is limited and the vertical drop from the fixtures is oversized also. Vent is same size as stack.
If this is wet vented, WC must be on bottom floor. A single stack system overrides this rule.
If I upsize the orange main vertical - do I need the AAV shown? Ie, stack serves as vent.
Does this also function as a single stack vent - circuit vent?
Check out this single stack vent system.
4 Types of vertical vent systems.

Warning: heater cannot be drained! Plug is on the side midway up the tank. Unless you turn it upside down. Just like normal: industry standard products suck in almost all cases - this well-recognized brand is no exception.

Wall Cavity
Can’t be below floor (readily accessible for cleaning gy UPC). Max height appears to be arbitrary, outside of max 60” to washer connection so washer drain hose can reach
Max appears no to be determined by 24” max from outlet to weir. For washer, it is from 18”-30” in UPC and 18”-42” in IPC
