After reading the "Grounding a Plumbing Drain Pipe" thread it reminded me
about something I found the other day while looking at my hot water tank.
Beside my Gas water heater I found a loose (not connected) bare copper wire.
Utility feed is PCV and changes to copper as soon as it enters the house.
Both the hot and cold pipes in the house are copper. All drain pipes are
Can I assume this ground wire should be connected to the copper plumbing?
Does the hot water tank offer enough of a connection to ground the hot if I
correct the cold grounding or should I get two clamps as there is enough
slack to reach both pipes.
What is the best way to test the ground. The wire runs away from where I
would have thought it should go so I want to make sure it does go to
ground - if one end is disconnected what did the previous owners do on the
other end? Would you test the voltage from a wall plug hot to the ground?
