Help needed moving & adding laundry to old utility room

[thegorilla]

Hi all, I need some advice and suggestions please.
In my downstairs utility room, I would like to change a utility sink to a kitchen sink, move my laundry connections from one wall to another, and add a laundry connection upstairs on the other side of the same wall (in a carport closet).

The utility room currently has a floor drain with 1.5" stack vent, a utility sink with 1.5" vent and drain, and laundry with a 1.5" standpipe and drain. The floor drain will be plugged, and that would leave 2 laundry @ 3DFU ea and one kitchen sink @2DFU so I think 2" pipe should handle all of it. Does my diagram with AAVs look like it will be correct?

I know the existing galvanized drain sizes are not up to current UPC and I want to correct this. Am I likely to find a 2" drain under the slab that I can connect these into?

This house has galvanized supply pipe (being replaced with PEX) and galv + cast iron DWV. All the closet flanges are 4", and the septic tank is SW of this room (back-left of viewer perspective).

Thank you!

Figuring the drain will be your first task.

Sorry, finding out whether you need a permit will be your first task.

Are you planning on having 2 kitchens? Find out if by doing so you will likely violate local codes.

Yes, some jurisdictions do not allow kitchens in the basement-- something to do with people using basements as rental apartments and in some places that is prohibited. So, it is best to find out if you are even allowed to do that.

I added one in my Redmond home. It was nice having one down and one up. I guess I didn't ask though. It was interesting wiring up a kitchen from the panel in the garage. I learned a bit.
