However, in many cases, and apparently yours, the water line is located far from the entrance panel. So a transient ("surge") may/will take a shorter path to ground -- like through your electronic devices. Which is Bad.
I would say that the water main comes in somewhere between 30-50 feet from the service entrance / fuse panel. The ground "wire" is in a 3/4" metal conduit run to the panel.
If I were then to add a new grounding rod outside the the service entrance I could just connect it to the first metal conduit electric pipe (closest to the ground pipe) coming out of the panel and it would serve its function I am guessing?
Thanks Marc for the info relating to grounding / surge protection. I noticed in FL there are grounding rods on both sides of the house and nothing is really grounded to the water pipes coming into the house.
