Anything wrong with this grounding connection?

[mbenerowski (Mark Benerowski, CHI CMI)]

Lead main piping connected to a copper section 8ft and then connected to Pex piping.

Thanks.

Here’s the NEC requirement for using a water pipe as a grounding electrode:

250.52 Grounding Electrodes.
(A) Electrodes Permitted for Grounding.
(1) Metal Underground Water Pipe. A metal underground water pipe in direct contact with the earth for 3.0 m (10 ft) or more (including any metal well casing bonded to the pipe) and electrically continuous (or made electrically continuous by bonding around insulating joints or insulating pipe) to the points of connection of the grounding electrode conductor and the bonding conductors. Interior metal water piping located more than 1.52 m (5 ft) from the point of entrance to the building shall not be used as a part of the grounding electrode system or as a conductor to interconnect electrodes that are part of the grounding electrode system.

If the pipe in question has 10’ or more in contact with the earth then it must be used as a grounding electrode and the connection point of the grounding electrode conductor (GEC) must be within 5’ of where it enters the building. Unless there is something that cannot be seen from the photo’s it seems like the installation is code compliant.

Is that a Ground, or is it a Bond???

[mbenerowski (Mark Benerowski, CHI CMI)]

Its the ground. I traced it to the panel.

Wouldn’t there be a dialetric union between the lead and copper?
Shouldn’t the GEC hit the lead pipe?

If there is, then I agree with you. I haven’t seen a lead pipe is a long time. Is a dielectric union always used between the two different metal pipes?

[tlarsen (Tim Larsen)]

To be honest I haven’t run into lead either and don’t know how it affects copper; however, galv to copper, yup.
