Galvanized pipe to copper pipe connection.

The easiest way to connect the copper and galvanized pipes is to use your wrench and unscrew the galvanized piece from the connecting threads. Whenever you join copper water lines to galvanized steel pipe you should be concerned about the corrosion caused by joining two dissimilar metals called galvanic corrosion an electrochemical reaction occurs that causes the steel pipe in this case to rust and clog up. Eventually galvanized pipe will have to be replaced and when that happens your choices are to replace it with more galvanized pipe copper pipe or plastic pipe. When water runs through pipes that are made of two different metals it creates an electrical charge that can cause corrosion and leaks in the pipe.

The reaction creates scale which will eventually clog the pipe. How to connect copper to galvanized plumbing. Next connect copper pipes together until you reach the galvanized pipe threads. It is possible to connect a copper pipe fitting to a galvanized steel pipe.

When connecting a copper pipe fitting to a galvanized steel pipe you must use a dielectric fitting. The problem with galvanized pipe is that it reacts with the minerals in the water supply. The dielectric fittings commonly available in home centers photo 1. To limit this problem make the steel copper connections with special dielectric unions rather than with a regular coupling.
