I've got my main water supply, galvanized 3/4in, that has a large bonding wire clamped to it. It runs across the unfinished basement, and ties into the electrical panel.

I'm planning on replacing my old galvanized plumbing with PEX. I understand my main panel needs both a ground rod, which is present. It's tied in via a solid copper wire, and close to the actual panel.

I was thinking of tying PEX in right after the main shutoff valve, as it's on a 3/4 galv pipe that comes up right out of the concrete slab - but the bonding wire is clamped at the ceiling.

Should I:
1. extend the bonding wire
2. tie PEX in after the 90deg at the ceiling, and leave bonding in place









My electrical panel bonding and grounding looks boned up too. That should be a separate post!

Typically the grounding electrode conductor is attached to the street side of the main valve as close to the wall as possible. This is done so if the piping system is disturbed the grounding remains intact. Also bond around water meter.

The bond/ground wire should be attached close to where the metal water line enters the house.

extend the ground, or replace it with a longer piece that will reach,


ground BEFORE your water meter/shut off....this appears to be after your water meter/shut off,


as close as possible to where your copper comes out of the slab

The NEC does permit splicing the GEC with an irreversible splice. Typically a crimp sleeve.
