While in Tractor Supply the other day I notice that they have Dielectric couplings for use between iron and copper pipe. Look somewhat like a union. Perhaps Donny can let us in on this dielectric scoop.

Bill,
They were made for use on the lines to the water heater. Breaking the electrical path makes the system work less like a battery and helps control corrosion to the heater tank. We were using dielectric couplings 50 years ago that worked even better since the dis-similar metals were separated farther. They were like a regular coupling but with an insulating fiber lining. In those days many water heaters were plain galvanized without sacrificial anodes... glass linings and mag rods are pretty much standard now, and the use of plastic pipe instead of copper helps too.

I'll bet there ain't no dielectric grease fittings on those dielectric couplings!!!!

If you can't fix it with a hammer, you've got an electrical problem.

Hi Fellows,
One only has to disect the word "dielectric" to determine what it means
and what it does electrically. Die- means to sease to exist in the same
manner and composition or simply to stop. Electirc-an oderless, tasteless phenomenon which is not fully explained nor can it be seen but sure
helps us out in our day-to-day living and will often give you the shock of
your life.
In face if this e-mail were all dielectric you could not be reading it now.

I like the definition in a picture I just received.

to restrain the people, it is an instrument for the people to restrain the
government lest it come to dominate our lives and interests." Patrick Henry
