This is a dielectric union. This device electrically separates the

I donno. Did you ask? We normally just don't spout off information unless
asked!
Someone a while back had commented on the corroded mess he had on the water
line of his water heater. I recommended dielectric unions then.

You didn't get the memo? Tom

Uhhhhh, ya think maybe that's why you have plumbers? Maybe at 90.00/hr they
don't want to give all their secrets away.

I also learned that a sanitary T cannot lay flat.
now this d.u.
i learned what a trap under a sink was for (silly but true)

anymore $90 hr secrets?

just one more, lemme get just one more

*when you can't think just use knoppix live

The Dielectrics have a union? What sort of benefits does it offer its
members?

Death benefits...?

I found these "secrets" and much more in "Remodel Plumbing" by Rex
Cauldwell. Lots of good info and photos, very useful for the amateurs.
The book is part of Taunton's series "For Pros By Pros" but I'm not sure
the pros would actually need it.

"The Complete Guide to Home Plumbing" by Black & Decker is also nice for
filling in some gaps from the first book (e.g. extensive rundown on pipe
types and uses). Both books are dirt cheap compared to potential repair
bills.

"Elron" Hubbard wouldn't allow unionization. Tom

I dunno, but I think they are listed on the sign for the shared hall I pass
on the way to work....

This is not a Dielectric fitting.
This is just a nipple with a plastic sleeve, that will not insulate from the
current.
You can check this easily with a DMM. Simple continuity test.
Granted I am sure it would not corrode nearly as quickly, as a unlined
nipple. But as soon as water gets between the sleeve and the nipple. There
is a space between the plastic and the nipple from molding. Plastic shrinks
as it cools from the molding process. It will start corroding.

I've been looking for a solution to the galvanic corrosion for many years.
My very hard water after softening is a very conductive electrolyte. Using
brass nipples supplied with a water heater, I got galvanic corrosion of the
tank near the nipples and early tank failure. Switching to galvanized
nipples, the nipples soon corroded at the dielectric connection. The short
path across the insulation is apparently easily bridged in conductive water.
But this is an improvement -- better to replace nipples every year or so
than an early failed heater.

Plastic lined nipples seem to be new to the market. They do provide a much
longer conductive path though the conductive water. I installed a pair a
year ago. The early signs of corrosion I experienced with the previous
steel nipples have not appeared and I am hopeful that this will be a
substantial improvement over the previous solutions. It will take some time
to conclusively prove their value but I am hopeful.

You didn't pay your dielectric union dues, silly.
