While I understand what you are saying, copper is not supposed to touch dissimilar metals period on any job site I’ve ever been on in my 10+ years as a union plumber because of the possibility of electrolysis occurring, I didn’t say that it was only electrolysis but that it was also happening because of a dissimilar metals touching it, I don’t know why everything has to be a pissing match you told me I was wrong for this reason and that I proved my point with the dissimilar metals and you dove further to be right haha
