I'm doing a kitchen remodel. My existing sink is in the corner right next to the vent stack. I'm keeping a small prep sink there but I am rearranging my kitchen so that the main sink and the adjacent dishwasher are about 10 feet away -- that is 10 feet away from the vent pipes. So what do I do? It would be very difficult and costly to run a new vent up through two floors of my house. How can I tie into that vent without an AVV(?) valve? Can I use the type of installation that I've seen used in kitchen islands -- that is, looping the air vent six inches above the drain and then just running a 10-foot run to the stack? Can I run an air vent above the sink, up the wall, and then across the ceiling to the stack 10' away? Any help would be appreciated.
