Hi. I am undertaking a kitchen remodel and found a small surprise when I pulled out my old cabinets. I intent to put the sink basically in the same location as the old one but need to move the drain about 2 feet over as the original location was actually in the cabinet next to the sink! Also the tie in to the vent stack seems to be an after thought of a previous reno as it is only notched into the wall. I want to fix the notches to bring this wall back to code. My question is how best to vent this sink?
