How Long Do PEX Pipes Last?

PEX piping is now more popular than ever for home plumbing. It’s cheaper, easier to work with, and less likely to leak or corrode. But is it really everything it seems?

Let’s explore the pros and cons of using PEX piping in your business or home.

What is PEX piping?

PEX piping is a type of plastic pipe that’s used to transport water and other liquids. The pipes are usually made from cross-linked polyethylene, an extremely tough, durable, and flexible plastic. PEX piping is often used in place of copper or galvanized steel because it’s lighter and easier to install.


Whatever your plumbing job, PEX piping is available in several diameters, from a quarter of an inch to three inches. It can be used in hot and cold water applications, withstanding temperatures up to 180 degrees!

PEX pipe easy to cut


Even better, PEX piping comes with multiple fittings allowing you to connect the pipes easily. In addition, the pipes are color-coded, meaning you know which line to use for hot, cold, or mixed-temperature water.

When is PEX piping used?

PEX comes in flexible hoses and rigid pipes that can be used for hot or cold water systems. The pipes can be installed in commercial or residential buildings, as well as in industrial applications.

If you need piping installed in a tight space, PEX pipes are perfect for the job. It’s flexible and pliable, so you can use it in places where regular rigid pipes won’t fit. You can also use them for radiant floor heating.

How long do PEX pipes last?

The life of your PEX pipes is determined by the type of piping you choose, how much it’s used, and how well it’s installed. PEX pipes are very durable and can last for decades if properly maintained. In fact, most manufacturers claim that they’ll last more than 50 years.

The Pros and Cons of PEX Piping

PEX piping has many benefits, but there are also some drawbacks to consider before deciding.

It’s cheaper than copper
PEX is less expensive than copper piping, making it a good option for homeowners looking for ways to save money on their plumbing work.

Easy to install
PEX piping is easier to install because it’s flexible and bends easily. It can be installed in a straight line or in a zigzag pattern. Also, PEX tubing is available in several different diameters. This makes it possible for plumbers to install PEX pipes in tight spaces that would otherwise be impossible with metal pipes.

Easier to cut
PEX pipes are made from a type of plastic polymer that is softer than copper or steel pipes. This makes them easier to cut when necessary. One advantage of this is that when installing PEX pipes in your home, you can make an adjustment after installing some sections of the system. If your measurements are off, for example, and you have too much pipe, it’s easier to cut.

Corrosion and freeze resistant
The main advantage of PEX piping is that it’s resistant to freezing. Unlike copper, PEX can handle temperatures down to -40 degrees Fahrenheit without cracking or bursting. This makes it an ideal choice for homes in colder climates.

And because PEX is made from polyethylene, an inert plastic that does not corrode or react with water, it’s less likely to suffer from leaks.

Drinking water safe
PEX piping is made from polyethylene, a type of plastic that can be melted and molded into any shape. It has been approved as safe for drinking water systems. The material is also free of lead, so it doesn’t leach into your water supply like older pipes.

Reduced plumbing joints reducing leak points
Another benefit of using PEX piping over copper is that it has fewer joins than copper. This means less chance of leakage or breakage if one joint fails. It also makes it easier to install since there are fewer joints to solder or crimp together. Fewer leaks mean less repair bills in the future.
It can’t be used outside
The problem with using PEX outdoors is that it will degrade over time, especially in direct sunlight. This is because the UV rays gradually corrode the piping.

Equally, PEX tends to crack and split when exposed to cold outdoor temperatures. Since insulating the pipes is difficult, it’s not suitable for outdoor use.

Rodent attacks
Rodents may attack PEX pipes because they are attracted to the scent of the plastic and the taste of the water inside. PEX is softer than metal, so it’s easier for them to cause more damage. The best way to prevent rodents from attacking your PEX pipes is to seal any openings in your home that allow rodents in.
