Copper vs. PEX: Which is Better?

More often than not, you don’t give too much thought to the materials your home’s pipes are made of — likely because you don’t really have to. But when it comes time to replace old, worn out pipes or you’re planning a remodel and are doing an overhaul of your plumbing, the materials you use for your pipes will be an important decision.

The main two options you’ll have for your new plumbing pipes are copper and PEX, each of which offers its own benefits, functions, and price points.

Pros of Copper

Old Reliable

Copper has been used in the plumbing industry for a long time, so there’s no doubt that it’s a good option for your home.

Resistant to Bacteria and Corrosion

The natural elements that make up copper help it fight bacteria growth that could otherwise affect your water quality. It’s also resistant to corrosion and UV rays, making it safe to use for any outside plumbing systems.

Cons of Copper


The price of copper has increased significantly over the years, deterring some homeowners from choosing it for their pipe materials.

Harder to Fit

Since it’s a harder material, it’s not that easy to fit and sweat copper pipes together, so you’ll likely need a professional to help.

Pros of PEX


PEX is a much cheaper material, so you won’t have to shell out as much cash to re-pipe your home.

Resists Heat Loss

Unlike copper, PEX doesn’t lose heat when carrying hot water, making them a more efficient option.

Easy to Connect

If you’re trying to make re-piping your home a DIY, you’ll have a much easier time doing so with PEX since it requires fewer fittings and connections.

Cons of PEX

Indoor Use Only

Although PEX is more resistant to freezing and bursting than copper, it isn’t resistant to UV rays and isn’t safe to use outside.
