Is there the same dielectric phenomena as with steel and copper connections. My local plumbing supply guy swears that because it is a closed system there is no need for the dielectric adaptors. I want to believe him because the pipes will be sealed in a ceiling and I would worry that the gaskets in the dielectric connectors might leak down the road leaving me with a bigger problem. If you agree that I need them, are there more permanent insulators?
