I don't top post - see either inline or at bottom.

When we had our electric service upgraded, the electrician (as
expected) ran a ground wire from the cold water main inlet to the
ground on the panel.

I read somewhere that one should also run a similar grounding wire to
the natural gas pipe inlet but the electrician didn't do that.
- Is it required by code?
- Is it recommended?
- Should one use the same gauge wire as for the water pipe?
- Any special considerations?
- Can I daisy chain it from the water pipe or do I need to run a
separate ground back to the panel?

Thanks
