WRONG. Completely wrong in every respect. The plumbing system is grounded to
the electrical system's grounding electrode to eliminate the possibility of an
electrical fault causing the plumbing to become energized. Pipes DO need to be
grounded in order to prevent this. Bonding the plumbing to the electrical
ground has *nothing* to do with grounding the electrical system, and
*everything* to do with ensuring that the *plumbing* is grounded.
