DIELECTRIC UNIONS

TERRY:
I HAVE A COUPLE OF QUESTIONS. WHEN YOU JOIN GALVANIZED AND COPPER PIPES TOGETHER, DO YOU NEED TO USE A DIELECTRIC UNION? IF YOU DO NOT, WILL IT CREATE A REACTION OR CORROSION? WILL THIS CORROSION TAKE PLACE AT THE SPOT OF THE UNION OR AT SOME OTHER PLACE? LET'S SAY THAT A LEAK DEVELOPED AWAY FROM THE SPOT OF THE UNION, COULD ONE SAY THAT THE LEAK OCCURED BECAUSE THERE WAS NO DIELECTRIC UNION INSTALLED OR THE LEAK HAPPENED FROM OTHER CAUSES?
