Change Galvanized Pipe To Copper

However replacing only part of the galvanized pipe with copper pipe can cause more problems when the zinc iron and copper react with the minerals in the water.

Change galvanized pipe to copper.

Copper plumbing is lead free making it safer than galvanized pipe. This fitting joins a copper pipe to a galvanized pipe called a union. Here is a chart detailing the dimensions of steel pipe. 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.

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. 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. Supply pipes under constant pressure and therefore most likely to cause water damage when they leak brass. 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.

Copper pipe is available in small diameters for installation in tight spaces. Plumbers quickly tell you that copper is easier to work with and because the work goes faster the job is less expensive. This eventually causes pipe degradation and leakage. Copper pipes are biostatic and inhibit the growth of bacteria.

Galvanized steel pipes were common in u s. Although galvanized pipes are coated inside and out to prevent rust they rust inside and will corrode over time causing a build up that restricts the flow of water and or the pipe may leak. Replace a portion of the old pipe with copper. Homes until copper became popular in the 1950s and 1960s.

Steel tube dimensions stainless steel tubing dimension dimensions of steel tube fifty years ago the industry thinking was that because of the inside of copper piping being much smoother than that of galvanized steel it was allowable to reduce the nominal size by one size when going from galvanized steel to copper.
