Galvanized Pipe To Copper

Plastic pipes are usually black and clamps should be visible.

Galvanized pipe to copper. Find the area where pipes enter your home and carefully scratch the pipe with a nickel. First you will want to coat the dielectric fitting with pipe tape. Copper pipes are biostatic and inhibit the growth of bacteria. Step 1 tape the dielectric fitting.

The fitting is generally made of galvanized steel and bronze. You don t need to wrap plumbing tape around the union before you screw it together. 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. It s far easier to make a repair to steel pipe with copper than with galvanized plumbing pipe because the galvanized calls for cutting threads on exact lengths of pipe.

Copper is the material most often used by today s home builders and homeowners when installing plumbing. Copper plumbing is lead free making it safer than galvanized pipe. 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. This fitting joins a copper pipe to a galvanized pipe called a union. Copper pipe is available in small diameters for installation in tight spaces. Galvanized steel pipes on the other hand are a steel gray color.

If the surface of the pipe is the color of a penny then the pipe is probably made from copper. Plumbing pipes such as pex copper and pvc are normally used depending on their application and the location in which they are installed. Also there are some other plumbing pipe types such as black galvanized and brass. 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.

This eventually causes pipe degradation and leakage. This will keep the water from creating an electric current and causing corrosion and leaks.
