Pros And Cons Of Pex vs Copper

Pex plumbing may be new to many homeowners in 2018 but it's actually been used in North American for over 40 years. It was first installed for the purpose of radiant floor heating and in 1993 it made it's way to the general plumbing market.

There are multiple pros and cons to both pex and copper. We recommend you discuss these with your plumber to make the best decision for your home.

Pex Plumbing Disadvantages

Generally, pex plumbing is an excellent product for residential water lines, sewage, heating, cooling systems and more. It's cheaper than copper piping and it's much easier to install. But, it's not all rosy. There are some disadvantages to using pex as we've listed above.

One of the cons that we listed is that pex piping is not suitable for outdoors. What we mean is that it should not be exposed to sunlight. That is a big disadvantage over other types of piping.

The reason for this is that when pex is exposed to sunlight, it begins to disintegrate. The piping then becomes brittle, cracks, ruptures and leaks ensue.

BUT - this does not mean that pex cannot be used underground. Pex can be used underground. It should be buried below the frost line and it's best if it's bedded in sand or stone dust.

Another disadvantage that many homeowners may not consider is that if you live in a wooded area or near the ocean, any location where there is a higher than average incidence of mice and rodents, then pex piping may not be suitable for your home.

It's very easy for animals to chew threw pex piping, and they will if they can access it. This of course will cause leaking and can result in some major water damage to your home.

Pex vs Copper Lifespan

Admittedly, the "facts" on the lifespan of pex do vary a bit. According to PexUniverse.com and Wikipedia, pex's life expectancy is anywhere from 40 to 50 years. It's not a huge difference and frankly, the liefespan estimates of most materials will always have variations depending on the conditions they are in, the amount and type of usage and other environmental factors.

Copper lifespans are much longer, an average of 50 to 70 years which can be advantage over pex.

Here's a list of the life expectancies of all the plumbing piping materials available.
  • Brass - 50 to 70+ years
  • Copper - 70 years
  • Galvanized Steel - 20 to 50 years
  • Cast Iron - 50 to 60 years
  • Pex Tubing - 40 years
  • PVC - 50 to 80 years
  • CPVC - 50 to 75 years
