Join Copper and Galvanized Steel Pipe DIY Family

Also be aware that directly joining two different types of metals, in this case, galvanized steel pipe and copper, can cause rapid corrosion at the joint called dielectric corrosion . To limit this problem, make the steel/copper connections with special dielectric unions rather than with a regular coupling. This type of union separates the two metals with a rubber washer and plastic 2
