After further review, the previous owners of our home are still the worst
 
at repairs. I keep finding more and more problems...
They replaced the 3/4 galvanized hot water pipe from the heater with 1/2 copper. So our entire house is restricted to that 1/2 pipe. Plus they went with straight connections, no die-electric unions.

Do you need help with something? Just trying to determine what this post is about...

no help, but thanks.

Just laughing about, and sharing, the problems of buying a used house.

Understandable.

As for the dielectric unions, or lack thereof, that is not necessarily a problem. In fact, dielectric unions are not all that common since they came out with dielectric nipples. Dielectric nipples thread right into the top of the water heater, and appear to be 3/4" galvanized nipples about 4" long. They have a plastic liner that you can't see once they're installed. They're advantageous because they do not break the electrical bond between hot and cold like dielectric unions do and therefore don't require the 8ga bonding jumper that is required when dielectric nipples are used (when the house is supplied and piped with piping that serves as a grounding electrode).

I have always wondered if the water would make the connection over a die-electric union in case of a grounding short?

Nope, water is actually a pretty poor conductor. That bonding jumper is a must with dielectric unions. A lot of plumbers do not understand that.
