How Long Do PEX Pipes Last?

You’ve heard all about PEX piping and how great it is. Maybe you want to install PEX instead of metal like copper because it’s faster to install or because it’s less expensive. And you may wonder how long PEX pipes can last and whether they stand up to corrosion. So, with that in mind, let’s find out all there is to know about PEX piping.

What is PEX piping?

PEX piping has been around since the 1970s but has recently become popular in residential applications. The main advantages of PEX are that it’s flexible, robust, easy to install, and more affordable.
You can buy PEX pipes as coils that you cut yourself using a utility knife or a pipe cutter tool. It also comes in prefabricated lengths already cut to length, with barbs attached at each end of the pipe. PEX piping is also available in a range of colors, which makes it easy to color-code your plumbing system.

When is PEX piping used?

PEX is a great alternative to copper, but there are some things you should know before installing it in your home or business. Here are some situations where PEX is the best choice:
  • When you need flexibility
  • In new construction
  • When water pressure is low
  • If freezing temperatures are common
  • To replace existing copper piping
  • For radiant floor heating systems

How long do PEX pipes last?

The average lifespan of PEX pipes varies, but it’s typically between 40 and 50 years. This is an estimate based on various factors, including the quality of the material used, how well it was installed, and how carefully it’s maintained over time.   In general, PEX pipes are very durable and can withstand high temperatures. They’re also less prone to bursting during freezing temperatures than copper plumbing systems because they don’t expand under pressure as much as copper does when they freeze.

The Pros and Cons of PEX Piping

Is PEX piping for you? Weigh up the pros and cons before you decide.
It’s cheaper than copper PEX is a lot cheaper than copper. For example, it’s estimated that the average cost of installing PEX plumbing is about 25% less than installing copper. Easy to install PEX piping is easier to install than other types of plumbing materials. It can be used in new construction and renovation projects because it’s flexible and easy to work with. The pipes come in different sizes and shapes, so you can choose the one that suits your needs best. If you’re unsure, always contact a professional plumber for the installation of your PEX pipes. Easier to cut The flexibility of PEX pipes makes them easier to cut and install than other plumbing systems. You don’t have to worry about breaking the pipe when putting it through walls or ceilings because it has less tension than other plumbing systems. Corrosion and freeze resistant PEX pipe is freeze resistant. Because it’s soft, it’s able to expand when the temperature drops, so it won’t burst during freezing weather as restrictive copper pipes can. Moreover, PEX pipes won’t corrode like copper when exposed to water over time. This makes them ideal for use in areas where corrosion can be an issue, such as kitchens or bathrooms. Drinking water safe PEX is non-toxic, so it doesn’t leach into your water supplies and cause problems with drinking water systems. In addition, the NSF has approved PEX for drinking water systems, so you can trust that the material won’t contribute to any health issues. Reduced plumbing joints reducing leak points PEX pipe connectors are made from plastic and have a smooth interior surface that joins by pushing them together. This is great because the connectors don’t require soldering like metal fittings. And this means fewer joints, resulting in few possible leak points.


It can’t be used outside PEX is an excellent plumbing material, but unfortunately, it’s not resistant to UV rays from the sun. Over time, these rays will degrade the pipes and make them brittle. It’s also unable to cope with cold outdoor temperatures without thick insulation. So outdoor use isn’t advisable. Rodent attacks Rodents attack PEX pipes because they are attracted to the smell of food waste or water leaks from your home’s plumbing system. Rodents have a keen sense of smell, which helps them find food sources. So, when an odor is present in your home’s plumbing system, they immediately flock to it and start chewing. This can lead to serious damage if left unchecked over time. Contact a professional plumber immediately if you notice any rodent damage in your home! They’ll be able to assess the situation and come up with a solution. Looking for affordable and efficient plumbing services for your home or business? Contact Moore Home Services today.
