Now that my hot water pipes are replaced with all PEX, I'm left wondering what I should do with my bonding wire. I left the galvanized in place, simply cut them with the Sawsall and left in place, but the end of the bonding wire is attached to it. It's the end of the bonding wire, clamped to the last portion of the galvanized that I haven't hauled away. Should I cut the bond wire at the next pipe in the circuit - in this case the gas line, or should I simply unclamp it from the pipe and leave it dangling, or should I leave the galvanized pipe in place even though it doesn't go anywhere or do anything?
In case it isn't clear, the bonding wire goes from the panel, to the cold water line, to the gas line, then ends at the hot water line. The water line was replaced with PEX, but the pipes are still in place as is the bonding wire.
