Should re read what I write sometimes. I was refering to using the water

thing and pemissable by the NEC, not sure if it still is.


When I replaced my service in 1975, a water pipe ground (which is all my
1952 house had) wasn't sufficient to satisfy the NEC, so I had to add a
ground rod. So the NEC hasn't permitted a water pipe ground as the sole
ground for at least 29 years. It apparently was permissible in 1952.

And I had a friend, had home in Springfield Or., was built during the WAR!
Home was plummed with (If you can believe this) Electrical Conduit! Apparently,
because of the shortage of materials, this met code then! Stuff finally rotted
out, around 1971-- remember him useing his vacation to replum the house!
And I had one , in K.Falls, OR was built as old farm house, with steel pipe,
that started leaking- electrolysis was rapidly eating it- replaced with Copper.
Was curious about the UNIONS used on it-- turns out that those are INSULATED JOINTS!
Plumber said had Copper pipes eating out in as little as 3-5 years, before they were
available, with them expected 25-30 years, before the pipe gives out! As running
current thru a pipe with an insulated connection is worthless as a ground, and even
current flowing thru a copper pipe, is hazardious to its health, don't think would
recommend this tactic if you want a good ground. Jim NN7K
