Another vent question

[Rick Beddoe]

Greetings! New member here. First post. I've gotten a lot of great info from this site so figured I'd sign up.

Facing a dilemma with placing a sink under a window. I have zero options to run any plumbing outside the studs. I've been trying to figure out how to possibly use the Chicago loop style venting seen in island sinks. The challenge in my case is that the sewer is in the opposite direction from what all the diagrams show. In this sketch, the vent is on the left and the sewer on the right.

Any suggestions for solving this problem?

i dont know about chicago loop but in an upc island vent looking at diagram the pipe on left would have santee for sink the one on right would have the foot vent take off . and the way your sketch is would be a fail

Thanks Jeff.

Here is the Island vent that seems to be the defacto way to do it:

But my sewer line is to the right compared to this picture where it's to the left, back toward the vent.

Could I do something like this:

Can you do something like this?

That would be ideal, but we're almost 100 year old 2x4 balloon framed - a "classic".

ugh
