Default Grounding wire from panel to gas pipe???

The water piping is bonded to the electrical ground in order to insure that
the _water_piping_ has a true electrical ground -- IOW, to prevent the water
piping from becoming live in the event of an electrical fault somewhere.

And this really is an important thing!

My mother in law's dishwasher developed a short to the incoming water
pipe. Most of her water piping is PVC, but some of the outside parts
are metal, and NOT bonded to ground.

We discovered this one day when she went to water the lawn while the
dishwasher was running. She reached for the faucet, and ZAP!
Fortunately, it was not lethal.
