I recently (about 8 months ago) had a "final plumbing" inspection on my house. The plumber did all of the rough in, and I did all of the finishing (installing faucets, sink traps, toilets, etc.) I got dinged by the inspector because I had my dishwasher drain hose hooked to my garbage disposer. He said that was against code and attributed it to centripetal force pushing waste back down the dishwasher hose. I thought all dishwashers had a check valve to prevent this, but even without, why would garbage disposers have a port to hook up the dishwasher if it causes problems? Just thought I'd run it by you guys and see what light you could shed on the issue. Anybody else heard of this?
