Bonding when water line is non-metallic

[gulf0927]

Rookie question. I'm upgrading a service to 200 amp. The home has a well-pump, no pubic water, and it seems like the water line coming in is non-metallic. However, much of the interior piping is copper, such as the hot and cold lines to the water heater. Is it necessary to bond the cold and hot lines to the panel, or is this unnecessary because the water line coming in is non-metallic? Thanks!

Yes, you would need to bond an interior water system.

250.104 Bonding of Piping Systems and Exposed Structural
Metal.
(A) Metal Water Piping. The metal water piping system
shall be bonded as required in (A)(1), (A)(2), or (A)(3) of
this section. The bonding jumper(s) shall be installed in
accordance with 250.64(A), (B), and (E). The points of
attachment of the bonding jumper(s) shall be accessible.

(1) General. Metal water piping system(s) installed in or
attached to a building or structure shall be bonded to the
service equipment enclosure, the grounded conductor at the
service, the grounding electrode conductor where of sufficient
size, or to the one or more grounding electrodes used.
The bonding jumper(s) shall be sized in accordance with
Table 250.66 except as permitted in 250.104(A)(2) and
(A)(3).

You still need to bond the lines, but they will not be part of the grounding electrode system. Two ground rods are what you need.
