ok i emailed the link to a friend i work with and this is what he replied back, the quoted text is from the link and the other text is his words. do u agree or disagree???
I don't know how old this is, but its flawed at best.
He has some points, but the majority of it is wishful
thinking. For example....
"We are actively soliciting the NFPA to change the
next revision of the National Electrical Code so it
would prohibit the grounding of electrical services to
Obviously this creates a hazard to everyone that has a
faucet, sink, hose, etc....and say a electric shaver,
an electric range, a portable plug in radio, etc. The
idea that the situation would never occur where
somebody would touch an electrically bonded surface
and a water line is ludicrous. Not to mention
"We feel that the interior piping certainly could be
grounded to the rod, but all exterior piping should
definitely not be part of this network."
How exactly do you propose to simultaneously prohibit
bonding of water services, yet bond them to the rod?
How will this change anything? Clearly this guy is in
the "electricity always takes the easiest path to
ground" crowd. Anyone whos ever touched a neutral and
a ground at the same time in a light fixture with a
load feeding through knows this is wrong. Not to
mention that this contradicts everything in the first
part of the paragraph.
"Therefore, isolation couplings and dielectric
couplings are being encouraged wherever we can in the
water industry to reduce the problem of corrosion in
mains and deterioration of the infrastructure through
the stray current problems."
If the problem is corrosion in the water MAINS, then
use the dielectric couplings or plastic service mains.
Why petition the NFPA to deliberately put millions of
people at serious risk to save a few man hours
maintaining water lines. What could an agency charged
with the task of assuring electrical and fire safety
have to gain by doing this? Liability? It'll never
happen... Also remember that potential (voltage)is not
always created through unbalanced neutral current, its
also created by long expanses of distance. If it
wasn't we wouldn't have any use for a Megger meter.
For example...the ground potential at my house is
different than the ground potential at your house is
different than the ground potential at my sisters
house, and so on....however, technically due to the
water mains we're all at the same potential. That's
the whole point of bonding. Deliberately lifting that
bond won't necessarily solve a deterioration issue.
Remember that PURE water (H2O) doesn't conduct
electricity, but the water we all drink and runs
through all of our houses is FAR from pure. Its
treated and chock full of fluoride and minerals,
particularly iron (among others) which conducts
"We know that our pipe, particularly if it is metallic
pipe, can lose approximately 20 pounds of metal per
year from just one amp of current flowing on the
pipeline in a path that releases the ground off of
...how much pipe are we talking about? 20 lbs of pipe,
or 20,000,000 pounds of pipe? Theres a useless and
alarmist factoid if I've ever heard one.
"We have even found instances where appliances have
been grounded to gas pipes because customers do not
always know the difference between gas and water pipes
in their basement."
That's not the reason. Actually, because of some
oversight in the electrical code, it both requires you
to and prohibits you to bond the gas pipe.
"My distribution people commonly tell me of electrical
shocks when they remove a meter from the water line,
indicating the tremendous risk to them."
If they're reckless, unqualified dumb-asses then they
deserve to get shocked, and the water utility deserves
to pay their settlements out of court. Don't blame
this on the electrical industry.
"We have not yet addressed the electrical shock
hazards from the AC (Fig. 6)"
"and certainly we have not been able to totally define
that AC current does or does not have a detrimental
effect on the operations life expectancy of a water
I don't think I even need to comment on this one...
This guy sounds like a corporate mudslinger out to
save his industry a buck on the backs of millions of
people who probably pay his salary and definitely pay
for utilities to be maintained. What are my thoughts??
