I recently accidentally knocked the ground clamp off of one of my two ground rods with my lawn mower. This rod is the one connected to the water line, not the one connected to the main service panel.
I had an electrician come out and he (understandably) would not replace the clamp because the rod is from the builder in the 80's and isn't up to current code. So now I am in a dilemma that I need to re-ground my plumbing, but I don't have a suitable grounding rod installed.
I know that for a new install, DIY is not an option unless you are licensed. This is a replacement. I would like to fix this myself. I am in Texas. I realize I have to follow the NEC.
I believe that fixing an existing install should be no more difficult than removing the old rod, installing the new one nearby, and attaching the ground wire from the plumbing.
The new rod will be 3/4" x 10 feet. The old rods are 1/2" x 8 feet (or shorter). I am not planning to replace the rod near the service panel myself, I will call an electrician for that. The service panel's rod is at least 40 feet from the rod I would like to replace, so I am well beyond the 20 feet minimum requirement of the NEC for 2x 10' rods.
Does the wire from the plumbing have to be upgraded as well? It's original and runs through the brick, and is a #8 (measured by my wire stripping tool). I believe the NEC requires #6 now for new installs and retrofits, but since this is not a new install or retrofit, I am not clear on the requirement.
I'd also like to confirm if there is anything else I am missing, unaware of, or just plain wrong about?
Any input is appreciated.
