40-50 yearsFact: The life span of PEX tubing can vary based on frequency of use, water quality and water temperature and has an average life expectancy of 40-50 years. Some factors, such as exposing tubing to sun or water temperatures beyond tested levels, can significantly damage tubing and reduce its life span.
Should I use PEX A or PEX B?
Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.
Why is PEX better than copper environmentally?
Water & Energy Use Because copper is a conductor, water traveling in the pipes loses heat on its way to the spout or showerhead. But polyethylene is a non-conductor and has insulation properties, which means PEX plumbing systems require less energy than copper systems to achieve a desired water temperature.
Why is PEX plumbing bad?
PEX failures Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also. On the other hand, fitting failure is caused by dezincification that results to corrosion and finally creating leaks.

PEX will not pit, scale or corrode like copper can. … So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
