Just wondering for now. Have an all copper plumbing. What happen to my ground if the pipes are replaced with PEX? Have two connections that I am aware of. One to the cold water pipe at water heater. The other one is ground rod by the meter.

So, what to do to the cold water ground? It is required by code here. Does that mean that PEX is not feasible?

Where I live, they just drive a grounding rod into the soil outside your house, connect the ground bus of the panel to that grounding rod, and that's your ground.

I would assume that you would have to run a heavy gauge copper wire back
to the panel ground bus. An electric WH should already be grounded however.

If you replace any segments with PEX I would make sure that any
remaining copper segments are grounded. I don't know the actual code
requirements but it's just a common sense good idea. Really if you have
all copper it would make sense just to do any repairs in copper to
maintain ground path.

The only thing grounded to the copper plumbing in my house (built '74)
was the telephone connection and it WASN'T grounded since the only part
of the plumbing system actually IN the ground was the plastic piping to
the well casing.g

Grounding of the electrical system was accomplished through a grounding
bar sunk into the ground and tied into the meter can at the service
entrance.

As for your hot water heater being grounded... it is, but if properly
installed, it's grounded only through the electrical service connection
since the incoming cold piping and outgoing hot piping SHOULD be a
dielectric fitting that isolates the hot and cold piping from ground and
each other to prevent electrolysis.

The metal plumbing system of the house by code needs
to be bonded to the electrical system ground. The telephone
line installed used the metal piping of the house,
which in turn is bonded/grounded back to the electrical
system. That's how it should have been done, anyway, so
I doubt the telehone line is not grounded. And if it
isn't done as described above, it's dangerous and should
be fixed.






Grounding of the electrical system was accomplished through a grounding

bar sunk into the ground and tied into the meter can at the service

And there' no bonding over to the metal water pipes of the house?

I think whether code requires dielectric unions varies by
jurisidiction.

You're right of course, I forgot about that. But the cold would also be
grounded even if it's electrically insulated from the tank. And I've
even heard tell about some jurisdictions wanting the hot bonded to the
cold around the heater, which seems like a good idea from an electrical
safety standpoint (and probably happens anyway even without a bonding
wire, at least in a house where there's a metal faucet hooked to both
pipes.)

Go talk to the building code inspector in your jurisdiction.
Only they can give you advice that will pass THEIR inspection.
When I replaced my underground water service pipe with pex
I found that what the codebook said and what they'd pass
were not exactly the same.

Richard,

For the reason that you raise here using water pipes as a ground is not
well thought of today. It may no longer be up to code where you are.
You have a ground rod by your meter. Most probably that is your ground.
It doesn't hurt to have the water pipes connected to the grounding system
whether they are serving as a ground also, or are separated from earth by
pex.

As we just went through exhaustively in another thread,
that isn't true. If you have an incoming metal water pipe
to the house, not only is it a permissible grounding electrode,
it's required to be used as one of the grounding electrodes.

On the other hand, if you mean being able to use a cold water
pipe at just any place in a house as a ground to tie something to,
eg CATV, sat dish, etcto ground it, for new work, that I agree
is not acceptable.

Dave,

I failed to mention (just remembered after reading other posts) that the ground to the water heater is ran/tied into the bus bar at the breaker. The bus ground is tied into a copper ground rod.

Reason I asked is I am thinking of having some of the main runs from just under the house (3/4") to some points closer to the 1/2" faucet pipes. I was thinking that PEX may be cheaper. However, I am not that comfortable in losing that secondary ground.

If I have it correct, it's not a secondary ground, whatever you mean
by that. You're talking about possibly removing a section of the existing metal water pipe serving part of the house and replacing it with PEX, correct?
Like replacing a section that goes to say the bathroom? If you do that you must run a bond wire to tie the sections back together again. It's not a secondary ground, it's almost always the only ground for those runs.

There is a bit of debate about bonding around plastic sections in

interior metal piping systems among the inspector community.

It is not specifically required in the code.

Doesn't NEC 250.104 (A1) cover it?

(A1) Metal water piping system installed in or attached to
a building or structure shall be bonded to the service eqpt
enclosure, the grounded conductor at the service, the grounding
electrode when of sufficient size, or to one or more grounding
electrodes used.


I don't see how that would allow one to take out a 10 ft
section of copper pipe in the basement that feeds through
to other parts of the house, eg the second story bathroom,
put in plastic and not bond it back together. That section
going upstairs is still a metal water piping system installed
in the building, no?

The problem is that many DIY repairs (imagine a frozen, burst pipe) do
not bond the pex. Such repairs are not subject to building inspectors.
It's not just DIYers either. Some years ago I bought a replacement water
softener from a large chain. They sent out a "professional". His van said
Plumbing. When he was done I noticed that he had bonded the inlet pipe to
the outlet pipe. Both pipes were pex. He and his helper didn't have a clue.

The code is failing in the real world.

I googled around a bit and it looks like this is a gray area and
a call to the AHJ sounds like a good idea. If all the piping in
a house is PEX, it does not appear that you have to ground the sinks,
showers, etc. On the other hand, let's say you
have a line that serves the upstairs of the house and you're replacing
one section of that in the basement with PEX, PVC, etc. Then the
plastic section needs to have a wire bond connection across it so
that the upstairs section remains grounded.

But what about cases that are in between? I saw one thread where
a contractor said the inspector required any metal piping that
exceeded 18" in length to be bonded. A call to the electrical
inspector is probably the best thing, if you're knowledgable
enough about how things are supposed to be grounded, bonded in
general. Otherwise, I'd get an electrician in there.

I think you have some serious fact checking to do. As good as copper
is, it is subject to corrosion and pin holing in certain soils. Ask
anyone who has had to have a plumber break through the slab to repair a
leak in the copper line. There were serious failures with polybutylene
piping, though it was the crimp rings used that caused most of the
problems. Pex seems to have become the piping of choice at this time.

Just wondering...

Considering the claims that PEX "doesn't have enough [water]
pressure"...

Is there a gpm limit (or some other kind of measurement)
when PEX is used (vis-a-vis copper)?

Will one end up with a whole house that behaves like a
2.5gpm shower head?

I'd be curious to know more about the claimed pressure issue too.
The inside diameter of the pipe is all that should really matter.
Replace a 3/4" copper pipe with 3/4" PEX and I would think they
would be close. I would think PEX might be a little less
because being more flexible, the pipe profile might not be
perfectly round. But this is the first time I've heard of
there being a noticeable, real world issue with it.

In fact, I thought that with the way PEX is typically installed,
ie central manifold with homeruns to various locations, it was
actually better with regard to good pressure, flow rates
at the various end points.

Hi,
I can only tell about our 7 zone PEX plumbed sprinkler system. Zone 1
nearest to the water main and Zone 7 furthest from it both have same
pressures when running. House is equipped with pressure regulator set at
60 psi.

....not speaking as an expert

The limitations would be related to the design of the system - I
guess. Some appliances can get buy on 3/8" PEX, others need 1/2".

I _do_ wish my hose bibs were 5/8" lines; not a 1/2" the needs a
copper stub-out for the bibs. hose bibs are not part of the manifold

The manifold has 3/4" coming in, then branches to each water feature.

My other house (selling) is that way. It takes forever to fill a 5gal
bucket in the slop sink and wash a car? Forget it. Never again.

So, what to do to the cold water ground? It is required by code here.
Does that mean that PEX is not feasible?

Why would anyone replace copper pipe with PEX? Copper is the best pipe
available, and should last you a lifetime. You want to replace it with
that cheap plastic crap that will probably fail in 10 years. You must
be an IDIOT!!!!

I think you have some serious fact checking to do. As good as copper
is, it is subject to corrosion and pin holing in certain soils. Ask
anyone who has had to have a plumber break through the slab to repair a
leak in the copper line. There were serious failures with polybutylene
piping, though it was the crimp rings used that caused most of the
problems. Pex seems to have become the piping of choice at this time.


You just responded to a troll. They're quite common and show up from
time to time and it's often the same freak who simply nym shifts. ^_^

TDD

agreed PEX is very good, easy to run, tolerant of being frozen, it just expands a bit...
'
best of all no one will steal pex, since it has no scrap values....

stealing copper plumbing is a big industry nationwide.......

a old friend is looking to buy a fixer upper, i have been going along with him.

most homes have all the copper stolen, one home had all the metal stollen including furnace and duct work, one home had most of the alunimum siding stolen.

if you replace the outdoor main line with pex its probably a good idea to leave the old copper line abandoned as a ground connection.

if anyone replaces a section of copper with pex then its probably best to install a copper ground jumper around the pex area

And, the jumper better be something sturdier/heavier/thicker/larger diameter than an old conductor from a telephone cable.

theres PRESSURE, and theres FLOW, as in gallons per minute.they arent the same.

which one is the problem?

Are you saying that they're not related? boggle
