In the past few decades, cross-linked polyethylene (PEX) pipes have swept the pipeline industry. The cost of PEX is much lower than that of copper pipelines. And the installation process is also easier. Therefore, it is not surprising that it has become a viable alternative to the old standard copper tube. In this article, we will guide you to understand the advantages and disadvantages of each method.

Unlike rigid copper pipes, PEX has flexibility. Can bend in different directions. It can be formed by turning around. And there is no need for a 90 degree elbow joint at every connection like copper pipes. The main value of having fewer joints is to greatly shorten installation time and improve reliability. But less turbulent water flow can also lead to higher water pressure at the fixed device and quieter pipelines.

In order to connect the various parts of the copper pipe, it is necessary to apply flux. Then use a high-temperature welding gun to weld the end. PEX does not require any flames. Use the expansion tool to "stretch" the end of the pipe, then slide the pipe over the joint and immediately shrink. Although this method is fast, when the tube contracts, it maintains tightness through a radial force of one thousand pounds. Thus forming a durable and long-lasting connection.

Although the installation time of copper pipes is much longer, they do provide a longer overall service life. Copper manufacturers typically offer a 50 year warranty period. PEX offers a 25 year warranty. But of course, this may vary depending on the supplier.

With the surge in copper prices over the past decade, it is not surprising that people now choose PEX solely because of its affordable price. There are many different manufacturers and types of pipes. But the average raw material cost is about 1/4 of copper. One advantage of copper pipes is that they are almost identical. Therefore, choosing a supplier may not be as important as PEX.
