The wording in 680.74 is such that only the metal parts associated with the water circulation system need to be bonded together. This would rule out the isolated parts like the faucet or water spout that are quite often metal and are connected to non-metallic piping system. Maybe.
Second point- If we have a double insulated pump there is no bonding needed for the pump and the cord of the pump contains an EGC and grounding of the metallic parts of the pump happens due to the cord/ cap connection to a grounded GFCI protected receptacle. Now, if I choose to terminate the #8 bonding wire to the grounding conductor of the branch circuit, is this a problem?
