Re: residential electrical question

Another reason for no electrical grounding to pipes is
plumber safety. A plumber must disconnect pipes and not worry
about things electrical - things that are not part of his
trade. Any electrical connection for safety must be unique to
that electrical purpose. Code also calls for jumpers from
cold water to hot water pipes at hot water heater, and jumper
across water meter.
