Hi Everyone,

The below pictures are of my (old) kitchen sink setup. To me there appears to be no vent. The picture from below the house seems to show the same thing because the 3" pipe that continues to the left connects to the plumbing that leads to the sewer...

From the inside of the kitchen picture I plan on moving the sink to the right and using it as a corner sink.

I want to me sure I do everything right and it is correctly vented. What is the best way to do this?

Should I just copy the ABS setup that I have and connect it to the main pipe under the house?
