"Many appliances say to connect to a copper water line NEVER to a gas line"
I don't understand what kind of connection that you are talking about.
If I had a gas furnace I would certainly want it connected to the gas line not the water line.
If you are talking about using a copper water line for grounding an applicance that is FORBOTTEN!
Code used to allow it, but has been illegal for many years.
Ground connections are only allowed withing the first 5 ft of where a metallic water line enters the building.
There are several reasons for the change.
One of which is that if the applicance has a defect and leaks current through the ground wire a plumber that happens to be working on that part of the line can become the ground path.
I understand that makes the plumbers very testy, if they survive. |
