Galvanized Pipe To Copper

Plumbing pipes such as pex copper and pvc are normally used depending on their application and the location in which they are installed.

Galvanized pipe to copper.

Solder the brass half to the copper pipe thread the steel half onto the galvanized steel pipe with teflon tape then join the two together tightly with the joining nut. Copper plumbing is lead free making it safer than galvanized pipe. Copper pipe is available in small diameters for installation in tight spaces. When connecting a copper pipe fitting to a galvanized steel pipe you must use a dielectric fitting.

Plastic pipes are usually black and clamps should be visible. Benefits of galvanized pipes. This eventually causes pipe degradation and leakage. First you will want to coat the dielectric fitting with pipe tape.

Galvanized steel pipes on the other hand are a steel gray color. Copper is the material most often used by today s home builders and homeowners when installing plumbing. This fitting joins a copper pipe to a galvanized pipe called a union. When water flows through pipes of two different metals the pipes will become eroded by electrical impulses from the slight acidity found in all water sources.

The fitting is generally made of galvanized steel and bronze. 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. Let s see below the best application for the most common used plumbing pipes. If the copper and galvanized pipes aren t the same diameter solder a reducing coupling to the copper pipe.

Copper pipes are biostatic and inhibit the growth of bacteria. This will keep the water from creating an electric current and causing corrosion and leaks. Find the area where pipes enter your home and carefully scratch the pipe with a nickel. Step 1 tape the dielectric fitting.

If the surface of the pipe is the color of a penny then the pipe is probably made from copper. The dielectric fittings commonly available in home centers photo 1.
