I have a 100amp residential service main to be grounded. I have the 8' ground rod but a pvc water main to the house. Where do I pick up my earth ground,(water pipe source), or do I need another ground rod within 6'?

rexowner said:I'm not sure if this is your question, but if by
"water pipe source" you are asking about grounding
a copper pipe system, you can ground it at any accessible
point in the system as you are not using the pipe service
as a ground. See 250.104. It would be common to do
it at the water heater if it is nearby the panel. If there is
plastic piping within the house, incidental copper such
as feeding fixtures doesn't need to be grounded.
As Dennis Alwon said, two ground rods will provide
the required ground for your service.
Pierre C Belarge said:The terminology at this point in the system would be "bond" not ground. (PVC water supply system to the building)
