I set up the drain lines, dishwasher, air gap and garbage disposal. An inspector writes up a correction notice stating I need a " tie bar between the dishwasher and garbage disposal ". What's he talking about? This is new to me. I asked another plumber friend. He didn't know either and said these guys have 100's of different names for the same thing. I even called a supply house to see if they've heard of a "tie bar". No luck. The only thing I can figure is the inspector wants to have some type of bar across the kitchen cabinet so the hoses can be tie strapped and supported. I've passed lots of inspections with the same set up. I just don't want to call the inspector at this point to give him the satisfaction that he knew something that I don't.
