Which Is Better for Repiping: Copper or PEX?

Monday, January 26th, 2015

Unfortunately, the pipes inside and outside of a home cannot last forever, and at some point, replacing older pipes becomes necessary.

Usually, a plumber won’t recommend re-piping unless there is rusting and corrosion present or if you have older galvanized steel pipes that are at risk of corroding in the near future. Today, galvanized steel pipes are replaced with one of two options: copper or PEX (crosslinked polyethylene). Which is better for your home will depend on the circumstances, which is why we’ve detailed each type of pipe to help you learn more.

PEX pipes are less expensive and installation goes much more quickly than with copper pipes. This is because the material is far more flexible, lighter, and far easier for your technician to work with. The pipes can bent to a certain degree in order to move around corners and other obstructions, so you don’t have to worry about buying a variety of joints and connectors. PEX is resistant to corrosion and is unlikely to burst. PEX pipes can be used for hot or cold water (and it’s commonly used for radiant floor heating) and can even resist freezing temperatures (which is not an issue in Los Angeles, but it’s good to know nonetheless).

Copper Pipes

One of the problems with PEX pipes is that we don’t know exactly how long they last since there have been few studies around long enough to tell. It’s estimated that most PEX pipes will last over 50 years, but copper pipes last 70-100 years. Unlike PEX, you can install copper pipes outdoors. Copper pipes are quite durable and generally resist corrosion, although pinhole leaks still develop in some cases.

Both copper and PEX piping installation are best performed by a professional if you want the pipes to remain durable and efficient for years to come. Call AZ Air Conditioning and Heating for professional piping services in Los Angeles.
