Relocated Kitchen Sink Options

[rjking2112]

Hi there, I am doing a kitchen remodel and would like some inputs into best option for plumbing the new sink. To help me sort through my thoughts I came up with the following sketch. I am thinking that I have three options. I am leaning towards Option 1 since it is easiest and makes sense to me since I have a vent upstream the the previous sink wyed into. Thoughts? I live in NH and my city (Nashua) adopted IPC 2000.

EDITED:
This venting is not allowed to go horizontal below 6 inches above the flood level of the kitchen sink. You pretty much will need an AAV.

With AAV, I think #1 is OK under IPC if you increase the pipe pipe size to the stack . Ideally add a cleanout above or below the sanitary tee, but the trap adapter at the wall may be sufficient cleanout.


A kitchen sink is 2 DFUs, and IPC allows a 1.5 inch pipe to carry 3 DFUs. Maybe you should increase the pipe in the floor to 2 inch downstream.

Are there any fixtures flowing into the 2" horizontal drain from the right side of the picture? If so, what?

Nothing to the far right but there is a input for a Saniflow up flow pump in the basement for a kitchenette sink that would tie in upstream of where I want to come down from the new sink on the first floor. That’s it.

Do you mean I need to increase the 2” horizontal drain?

I had missed that was a 2 inch drain under the floor. Your drawing was clear.

A 2-inch shared drain line below the floor may be sufficient after you add up the loads.

Ok great. Looks like I have 6 DFU (2 sinks and the tub upstairs) so I think I’m at the max for 2”. Thanks for your help.
