Island Sink / Venting Options

[Wasif Khan]

Hello,

I am currently going through a kitchen remodel where we will be putting in 10' x 6.5' of kitchen Island. As a part of this remodel, we will need to move current drain along with hot/cold waterlines.

What are some of the options to consider? I will take some pictures and upload them.

Thank you MKS. Question. in a Loop back vent, how far can that vent that goes out to roof can be from drain.

I do not know.
I would guess if you replicated the island drain/vent from the PDF, went up a wall and tied back into the vent for the original sink you would be in the ballpark. Of course using the appropriate fittings a slopes.
