How Long Do PEX Pipes Last?


We’re all looking to keep costs down. So, if you need plumbing repairs, PEX piping is a great option. But how long does it last, and is it better than traditional piping like copper?

There are lots to think about when choosing the best piping. So, let’s explore whether PEX piping is the right choice for your business or home.

What is PEX piping?

PEX is a flexible plastic tubing used to carry water in residential and commercial buildings. It was introduced into the U.S. market in the 1970s but only really caught on in the 1990s. It’s now a popular choice for many plumbing systems.

PEX is available in various colors to help you determine the temperature of the water flowing through the pipes. It’s flexible enough to be used for hot and cold-water lines. It can also be bent into different shapes without kinking or cracking.

Because of its flexibility, PEX piping is used in a variety of applications, which include:

  • Hot water lines
  • Cold water lines
  • Drain lines

There are different types of PEX piping available. Ask a professional plumber if unsure of the type you need for your home.

When is PEX piping used?

PEX piping is an excellent option for home plumbing because it’s flexible, easy to install, and doesn’t rust easily like copper. The plastic pipes can be used in residential and commercial plumbing projects, but they work best in low-pressure applications like sinks, showers, and small appliances.

What makes PEX piping great is its flexibility. It can be bent into different shapes, which makes them ideal for plumbing projects that involve tight spaces or angles, like kitchen sinks or bathrooms.

How long do PEX pipes last?

PEX pipes have a lifespan of between twenty-five to forty years. However, they can last much longer if they are correctly maintained and serviced by a licensed plumber. This is because PEX pipes have been made with high-quality materials.

The Pros and Cons of PEX Piping

Is PEX piping right for you? Here’s what you should know before deciding.


It’s cheaper than copper

Copper is a great material for plumbing, but it’s expensive. PEX piping offers a cheaper alternative.

Easy to install

PEX piping is easier to install because it’s flexible and bends easily. It can be installed in any direction, so it doesn’t need to be laid out in a straight line. This makes it ideal for plumbing systems that are hard to reach or inconveniently located.

Easier to cut

PEX pipe is easier to cut than metal piping because it’s made of a softer material. As a result, it doesn’t require the use of a hacksaw or other major cutting tools. The plastic also has no sharp edges that could cause injury while handling.

Cut PEX pipingCorrosion and freeze resistant

PEX pipe is very resistant to corrosion and freezing. It can withstand temperatures as low as -20 degrees Fahrenheit, making it an excellent choice for areas with cold winters. Another advantage is that PEX is more resistant to chemicals than copper or CPVC pipes. Most chemicals won’t damage PEX pipes but can eat away at other plumbing materials.

The National Sanitation Foundation (NSF) studied whether PEX pipe was safe for drinking water systems. The study found that PEX was just as safe as copper and CPVC pipes, the two other materials used for piping water systems.

Reduced plumbing joints reducing leak points

PEX has fewer joints than copper, so there are fewer places where leaks can occur. And unlike copper, PEX pipes do not need compression fittings or solder to join them together. This is good news for your home, as fewer leaks mean less costly repairs later down the line.

PEX pipesCons

It can’t be used outside

When exposed to UV rays, PEX piping can develop pinholes that could potentially leak water. Since PEX pipes aren’t watertight when damaged this way, they can’t be used outdoors where they would be exposed to direct sunlight.

Similarly, PEX piping isn’t suitable for outdoor use in cold climates as it’s impossible to insulate the pipes properly.

Rodent attacks

Pests that like to gnaw on PEX include rats and mice. Once in your home, they attack your plumbing system because they need water to survive. Their keen sense of smell leads them to the pipes. It’s more difficult for rodents to damage metal piping systems, although it is still possible!

PEX piping has a limited 50-year lifespan compared to copper pipes which can last up to 100 years.
