Recently there was a post where the subject came to the reaction of galvanized pipe to other metals. Do not know where it is right now, so posting here.

I have a galvanized frost hydrant that has been replaced once. It was hooked up to copper, right now it is hooked up to stainless steel.

The question is will I have the same problem or will I have to go to some sort of hose between the two to prevent the galvanized pipe from having a chemical reaction and leaking again?
