I am remodeling my kitchen and have a new 10 inch deep stainless steel sink to install with a garbage disposer. The current/old sink drain is too high for the new deep sink with disposer and I am working through options to lower my stub out. The drain currently runs through the stud bays in an exterior load bearing wall. To drill holes lower for new drain pipe would mean weakening these studs to a point that is dangerous....I am trying to find a solution that avoids having to replace these studs and drop my drain straight down into the basement where it could connect into the main drain out. My question is can I use this current horizontal pipe as the vent with the waste drain going straight down? If not any other ideas are greatly appreciated. I am in Virginia and under IPC.
