PEX vs Copper Tubing: What's Best For You?

by Dave Logan


Copper tubing has been used for decades by plumbing professionals, and even most customers are familiar with it. Modern times create modern technologies. And modern choices. Today, we’re going to take a look at one of these choices for plumbing: PEX tubing. Having choices is always good, so we’re going to discuss a few of the advantages of each so you can make the best decision for your home or business.

Let’s start with PEX…

What is it? PEX tubing is cross-linked polyethylene pipe. It is extremely durable in hot (200 F) or cold temperatures (below freezing) and can handle long-term exposure to stress and chemicals. PEX is a flexible material that makes for easy installation by your professional plumbing contractor because it has fewer joints to work with. Easier installation means faster and less expensive! In terms of pricing, PEX is also considerably cheaper than copper.

Advantages over copper?

  • Considerably less expensive. ? Easier to install and work with.
  • Fewer fittings for fast installation and less leaking.
  • Superior flexibility for expansion and contraction.
  •  PEX can be bent around most corners without coupling or fitting.

Now on to Copper…

We know that copper is durable and flexible because it’s been used for decades. Installation is somewhat easy (though not as easy as PEX) as well. Copper piping is also extremely resistant to any bacteria growing inside it and contaminating your water, making it a positive health solution. Copper greatly resists corrosion and is not affected by ultraviolet rays, which means it can easily be used for outside needs.

Advantages over PEX?

  • Safer in disasters (resists burning).
  • Weather and bacteria resistant. ? Better corrosion resistance.
  • Can be used outside (resistant to UV rays unlike PEX).
  • Recyclable, more environmentally friendly.

I hope this has been helpful for you. It’s beneficial to know your options so you can hire a professional plumbing contractor to better answer your questions and help you with all your plumbing needs.
