Have you ever wondered what the various pipes in your home and other buildings are made of? How come some Denver plumbing systems use different materials than others? What are the differences between common types of pipe materials? This brief guide covers all those questions.
The newest piping material is plastic. Usually made from acrylonitrile butadiene styrene (ABS) or polyvinyl chloride (PVC), plastic piping has been in use in some form or another for about 50 years. Although many purists tend to shy away from plastic piping, it is popular as a material for both water supply and drain piping because it is cheaper and easier to cut than copper, and doesn’t present the corrosion problems of other metal piping materials.
Sometimes, plastic piping can crack or break because it was installed improperly, especially when done by an installer who is not used to working with ABS or PVC materials. These pipes have to be installed differently than copper would be, so it is important to use a contractor with expertise.
Despite the relatively recent popularity of PVC and ABS, copper has been and remains the industry standard for most piping jobs, especially building water supply lines. Copper has advantages over other metals in that it is softer and easier to manipulate, doesn’t corrode easily and isn’t toxic to humans and animals.
There are three kinds of copper piping used in plumbing, which are assigned letter types depending on the thickness of the pipe walls. Type M is the thinnest and is used for above ground plumbing, while Type L and Type K copper piping have thicker walls. Occasionally, flexible copper tubing is used for plumbing, but because of the high cost, use is usually limited to spaces where the extra flexibility is essential.
Galvanized steel piping is not commonly used for drain piping or building water supplies any more, with both copper and plastics being far more common choices for new construction. The zinc coating on galvanized pipes stalls rust, but doesn’t prevent it completely, which can shorten the life of the pipe and cause flaking on the interior pipe walls.
Although not often used in new construction, cast iron can still be found in a lot of buildings because it has been used as a plumbing material for more than a hundred years.
Lead has been found to be toxic to water supplies and should never be used in new construction. Nearly all buildings with lead piping have had the water supply and drain piping replaced with newer, safer materials.
