Thanks for your input. Has anyone heard of this being a problem, particularly since the code requires a ground to the copper water line within 6 feet of the exit frm the building? It's probably easier to add a new ground rod than to inspect the existing grounding and compare it to 1970 code. Since there is no room for another pipe clamp I assume 1: The existing connection at the neutral block will be removed. If a grounding conductor is Water lines are generally not required to be bonded to ground within your house unless they are metal. 2: A ground wire from a new pipe clamp would be lengthened to bond to the ground rod, and when the ground wire reaches the rod it would make a right turn back to the neutral block. Each of these causes has particular factors and must be mitigated individually. NEC 250. I assume this was installed so any electricity First of all do you mean you are replacing the copper with PEX?
