i think this maybe a dumb question..

plastic water pipe coming into a home and turns to copper just inside the foundation, the water pipe needs to be bonded regardless of the fact its not in contact with the ground..no?

also, how does the code treat these new homes that have all plastic water piping systems until they reach a faucet etc. ?
 
Bonding:The requirement in 250.104 is for bonding of a metallic water piping system.
If its PEX and metal stubs under a sink, then is not a metallic system.
Grounding: A metallic water pipe is only a GE if it has ten ft in contact with the earth.
 
but if its plastic coming into a metallic waterpipe system, its still required to be bonded even if its not being used as a GE...

Yes if there is a metal water piping system it must be bonded.

But you had asked this;

It seemed you where asking about a home with a plastic supply and a plastic interior water piping system.

In that case you have nothing to do except find or install another suitable grounding electrode

No, it's not; and yes, it is.
 
Which usually works out good for me for some reason, since most of the time the service is on the other side of the building... :) and I dont have to be within 5' of the water entering the building...
 
If You Have Plastic Hot & Cold Water Lines, Plastic Water Lines Coming In From The Outside, Plastic Gas Lines.... Now Where Would You Ground To?

Gas Black Pipe Are Stubbed At The Meter, Hot Water, Furnace And Fireplace.... Now Where Do You Ground To?

Ufer Ground Or/and 2 Ground Rods????

You would be required to use the CEE if present or if not, then 2 ground rod would do.

I think your confusing a GEC with bonding something thats metal...

You must install a grounding electrode or electrodes, one of more of the types listed in 250.52(A).
The gas piping is bonded by the circuit that will energize it, see 240.104

Even if the piping is all metal, inside and out, you don't have to land within 5', unless you want the pipe to qualify as a grounding electrode.
 
Yes, I did not actually know it was an option, but I think i've only done maybe 2 houses that had city water, the rest have a well with plastic leaving the house...:)

When feasible (read- easy) I try to bond the interior metallic water piping within 5' of where it enters the building if the building is on a well with plastic line coming in. As more and more rural roads have "water coming through", the new city feed line is often metallic. That way, the work is done for later on. Just one of those little things that might help out the next guy, if you care to do a little extra.
 
they will probabaly never have city water... I live/work in the country, thats why they call it city water...:) In reality the houses are just too far apart IMO to justify the cost... But you are making a fine point to help the next guy....
 
Some years agowhen interior plastic first came out, I got a call from an EC asking the same question.

Being in a festive mood, I told him he needs a plastic bonding clamp. Taking me 100% seriously and not missing a beat, he then asked if I knew of a wholesale house who stocked them. At that point I told him I was kidding and proceeded to talk serious. He was a good sport about it.
