It’s really important to get the material right for your plumbing projects, because that decision affects the durability, cost and long-term maintenance of your pipes. When you’re weighing up the decision between PEX and copper pipe, consider how each one performs in your specific environment. Let’s take a look at how you might choose between PEX and copper.
Comparing performance and durability
PEX is a flexible plastic piping that has become really popular in modern plumbing systems. Its ability to expand and contract makes it quite resilient in colder conditions, as it is less likely to split if water freezes inside, making it perfect for our UK winters! It’s also resistant to scale build-up and corrosion.
Copper pipe, by contrast, has a reputation for strength and longevity. Properly installed copper pipe systems can last for decades and are naturally resistant to bacteria. However, copper pipe is rigid, which means it doesn’t really tolerate freezing in the same way PEX does.
Installation, cost and long-term considerations
Installation is often simpler with PEX due to its flexibility. It can be threaded through walls and around corners with fewer joints, reducing labour time and potential leak points. This usually makes it a more cost-effective option upfront.
Copper pipe requires soldering and precise fitting, which can increase installation time and expense. Copper is also recyclable, which may appeal if environmental impact is a key concern.
So, it all comes down to what your property conditions are. Either way, you’ll need to choose a plumbing system that performs reliably for years to come.
