I was inspecting an older home in one of my towns last year and the homeowner was doing everything himself. When he got to his water line, he cut it in several spots (hot and cold) and installed anywhere from 8 to 12 pieces of plastic water pipe because he had to remove the copper in order to install beams, lights, duct work, etc. So as I was looking around I mentioned to him that he broke his ground of the water pipes. He asked how to fix it and told him he would have to install jumper wires from hot to cold on every piece of plastic that he installed in order to make sure that his copper water lines on the second floor were properly grounded.
