Dielectric union

Hey folks. Thanks for the reply. When I asked how is a dielectric union tested, I was refering to testing it for its electrical current blocking abilities. I had thought of using an ohm meter to test for continuity, however, with water in the pipes, it would not ohm out. I thought of using low voltage on one side and checking the other but the same would be true as in the first senario. Your reply's are apreciated.

You're right, I was wrong.
It has to be detached or completely drained to test for continuity.
WHAT was I thinking? LOL

I'm not so sure it has to be drained off to test, take a water heater element, it is tested while in water.

If the union test with no ohm resistance then the union is working.

When I test I test at the 200 setting for a water heater.

Now I just did a test with a glass of water, when the meter was set the the 200K or the 2000K setting there was a reading.

So when you test put the ohm meter on the 200 setting and not on the ???k settings.
