Bonding ground to plumbing

[Copymutt]

Sooo, just wrapping up a broken water line issue 3Feet under an in floor heat system. Had to reroute a new feed. Terminated the original galvanized stub up. I did rebond the system ground to what was left of the pipe as it comes up thru the slab. Question is, do I need to also tie a ground to the water feeds (sink,shower,john etc) that are now insulated from the original feed by Pex and PVC?
This was an SOB, only way I even knew there was a leak was a monitoring pressure gauge I installed in the garage bathroom 24 yrs ago.
Thanks in advance.

It doesn't hurt to ground any metal you can come in contact with or has a possibility of becoming energized.

Is the water service feeding the house from street copper?
If it is ,the electrical service should be bonded to it on street and house side of meter.

On a well.
This water feed is the garage. Home plumbing is fully grounded as was the garage. One situation came to mind after my initial post & sberry’s comment. I couldn’t think of any possible way the pipes could become energized, then I remembered the electric water heater. I’d prefer to trip a breaker than be the ground connection myself so I’ll tie in the copper branch lines.
Thanks

Water heater needs to be grounded with the current carrying conductors.

I stand corrected, the H2O heater is grounded via its feed. Can’t think of any other way the plumbing could become “energized”.

I was in a house under construction in my neighborhood several years ago. Noticed PEX plumbing throughout the house, only thing brass was the pressure regulator. It had the electrical ground attached just to the brass regulator. Lots of good that does. Passed code it been 10 years or so ago now. Also the plumber read the blueprint upside down and had the cold water for the refrigerator stubbed up in the slab in the middle of the living room. All the plumbing was in the wrong place coming out of the slab and then run sideways through all the walls to where it was supposed to be. Really a big mess.

What if an energized line came in contact with the regulator? It is brass and conductive after all. I don't know the code, I'm just guessing. Could also be the local county's code.

Aren't there any ground rods at the service panel, at least one?

The ground isn't a current carrying conductor.
Don't you mean bonded?

At the point the water enters the building, the pipe needs to be bonded if it is metal. If there is a meter both sides of it need to be bonded with your grounding conductor.

I tied the now electrically isolated water lines back to the cut off Galv. Stub up this AM, I’m good to go.
This discussion brings up an old debate on watering ground rods. 2018 was a severe drought here with huge cracks in the clay earth. No irrigation, no rain. I’m sure all my ground rods were poor to non existent in function. Totally spaced keeping them damp. Anyone want to volunteer symptoms that could have arisen.

nothing, unless you had a fault to Ground in your system.
as stated, the ground is a non current carrying
it's there to protect you and the rest of the system from a metal housing being energized by a fault
