When you’re upgrading your home plumbing, one of the first questions is usually whether to go for PEX piping or copper pipes. There are pros and cons to each but they basically depend on the purpose and situation.
What is PEX piping?
Not come across PEX piping before? It stands for cross-linked polyethene, and it’s a highly durable, flexible and resistant plastic tube that can withstand corrosion well. It’s commonly used in radiant heating and modern plumbing systems and is generally used as a first choice by plumbers over PVC pipes and rigid copper. That’s because, unlike copper, which needs more complex pipe fittings https://watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems, PEX pipes are easy and cheap to install, and the material is also resistant to freezing temperatures.
Why might you choose copper piping?
If we know that PEX is going to be a freeze-resistant, flexible and cost-effective solution for domestic pipes, why would we even consider copper pipe? Well, copper pipe is the durable choice, lasting over 50 years with proper installation, and it’s highly rigid and proven.
There’s also no risk of microplastic leaching, which can be a concern with plastic pipes and water supplies. Copper is also naturally antimicrobial, making it a good choice for water, and it doesn’t easily degrade in UV light. What’s more, it’s easy to recycle. However, there are cons with every material, and it can become corroded or pitted if your local water is very acidic.
The best choice for your project will depend on your needs, intended lifespan, project scope and budget.
