I am in need of some advice from the regular pros. This will be a bit long, but I want to make sure the details are clear.
Background:
We are in the process of remodeling a family member's 100+ year old home. The previous owners "DIY" remodeling projects are a disaster... Extension cords inside walls, unvented add on bathrooms, unvented kitchen, cut BEAMS and joists to route ducts, drains, wall cavities as DUCTS (not returns), etc.
Anyway, we are correcting things as we go but the kitchen plumbing is next on the list. The images below show the proposed plumbing layout.
EXISTING LAYOUT:
The 4" ABS waste line branch I am going to tie into runs below the concrete floor and ties into the main soil stack and city sewer on the other side of the basement. Currently the 3rd floor apartment sink drains via a 1.5" vertical drain (vented through roof) to basement (not shown on my renderings) and ties into the END of this 4" run. The basement washer and laundry sink tie into that 1.5" apartment drain and are wet vented through the 3rd floor apartment. The END of the 4" run has a 90 bend that sends it up through the concrete floor.
The kitchen (20 feet away, along the same wall) was tied into vertical stub of the 4" branch and was vented via a STUDOR under the sink.
The kitchen plumbing has ALL been removed. The laundry plumbing WILL be removed, leaving the 3rd floor apartment kitchen sink and DW as the only fixture on that 1.5" vented drain that ties into the 4" branch.
PROPOSED NEW PLUMBING:
RED = NEW VENTS
BLUE = NEW DRAIN/WASTE
GREEN = EXISTING 4" WASTE
YELLOW = FITTINGS
The drain and vent MUST come through the kitchen cabinet floor, there is no way to route them through the joist space into the wall cavity! I will then route the vent through the back of the cabinet into the wall and up to the roof.
A basic overview of the proposed plumbing with the framing shown.
The proposed Tie-in to the 4" vertical stub.
The kitchen sink are showing the framing. Vent comes through back of cabinet in two places. One to tie into sink drain and the second to extend past foundation into basement. The sink drain extends straight down.
The proposed wine room sink area on the left and the laundry area along the back wall and right.

- I have extended a 2" ABS vent straight up-wards on the outside wall through the 2nd and 3rd floors to the roof. The location is the ONLY place it could go.
- I plan on tying a 3" horizontal to the 4" vertical stub that is protruding above the basement floor with a 4x4x3 Sanitary Tee.
- There will be a new 2" clothes washer standpipe on the new 3" horizontal
- There will be a new 1.5" (2" if needed) laundry sink on the new 3" horizontal
- There will be a new 1.5" aux sink on the new 3" horizontal (wine making room)
- The new kitchen 2" drain will tie into the new 3" horizontal
- The new 2" vent will tie into the kitchen sink trap AND continue down to the new 3" horizontal.
The drain and vent MUST come through the kitchen cabinet floor, there is no way to route them through the joist space into the wall cavity! I will then route the vent through the back of the cabinet into the wall and up to the roof.

QUESTIONS:
- Can the COMBO WYES in the basement lay on their sides as shown for the two sinks?
- Is this vented properly?
- Is there anything else wrong?
