Question - in all that talk about using water pipes for grounding,
someone mentioned bonding the water heater inlet and outlet pipes
together. If you're 100% PEX from the water meter, would that be
necessary?

No, you don't use water pipes for grounding, you ground the water pipes. A
subtle, but important difference.



In an older house it is possible that the water pipes were used for
the ground and that the pipes are in fact still the one and only
ground on the premises. If that is the case it will be necessary to
install a code-approved ground when replacing the pipes
