I need some help. I do mostly heavy industrial work so my resi knowledge is a little weak.A guy from the shop got into an argument about grounding the water pipe to the panel of a small building he was remodeling. The inspector had required it to be connected yet the water dept refused to connect his water service until this was removed. Then a contractor he was working with, who had moved here from Calif. stated that grounding the water pipe was illegal there! Can anyone here help me clear this up? I hate these conversations that always seem to come up when a Jack Of All Trades, Master of None starts running down the codes and rules we all have to follow. It makes it tough to defend why we do what we do!
