I was watching this old house yesterday and Richard was installing some new work on a boiler. He threaded a copper male adapter into a galvanived female tee. I was always under the assumption that was a problem-2 dissimilar metals touching. I've taken out 10 year old water heaters with the copper male adapter threaded right into the tank with no evidence of corrosion. Is this a problem or is it overblown?
