CPVC grounding?

[Tech420]

Do CPVC domestic water pipes in a high rise residential unit with copper risers require that the CPVC branches be grounded?

How do you ground plastic pipe?

I hope the OP just mis worded that..........

It is not an error. I work for a construction management group and we are thinking about changing are branch piping from copper to CPVC because of the drastic inflation of copper prices. My electrician is telling me that if I do this I will have to ground every CPVC branch back to the panel. I have never used CPVC in a high rise before and have never heard of having to ground it before. That is why I am here asking the experts.

So you guys are saying there is no way to ground a domestic water CPVC pipe?

It sounds like there is a miscommunication between you and the electrician.

Plastic bonding bushings, you can get them at the same store as sky hooks which are used to support aerial cable when poles aren't an option.

Tech420,

To get a straight answer We need to know exactly what you have existing

and what exactly is being changed and what part of the copper will remain.

Definitely a problem with terminology.

We don't ground any piping system. The correct term is bonding. We cannot bond non-conductive material.

How much of your system will be CPVC and how much will remain metal?

I like the rope and tie wrap idea the best

I can`t tell you how many times when checking a rough in I have found the entire house done in CPVC.Except for a copper stub out near the meter for a hose bib.The rough guy sees the stub and automatically hits it as part of the grounding system.What gets me is this.The entire house has CPVC slab walls etc. But the guy still hits the copper stub out??????

Does the rope have to be green or green tape at the ends?

"My electrician is telling me that if I do this I will have to ground every CPVC branch back to the panel."
Ask your electrician to read 250.104.
The requirement is to bond a metal water piping system. You have a plastic water piping system with metal stub outs.
Whats going to energize the metal stub out under a sink?
In Washington State we have a state code rule that clarifies this.

Short of sending it to its room and not letting it use the car Friday night, yeah.

I'm with Bob, I wonder if maybe your EC miscommunicated something to you.
