Copper vs. PEX: Choosing the Right Material for Your Repiping Project

Copper Pipes: The Old Favorite

Copper pipes have been used for decades. They’re strong, long-lasting, and can handle heat well. Many older homes still have copper pipes, and they’re known for lasting up to 50 years or more.

Pros of Copper:

• Durability: Copper doesn’t break down easily and is resistant to bacteria.
• Heat Resistance: It can handle hot water without getting soft or warped.
• Value: Copper adds resale value to your home since it's seen as a high-quality material.

Cons of Copper:

• Cost: Copper is more expensive than PEX, both in material and labor.
• Rigidity: It’s harder to install because it doesn’t bend, which can raise labor costs.
• Corrosion: In some areas with acidic water, copper may corrode over time.

If you like tradition and are looking for something strong and time-tested, copper might be your best choice. A plumber can inspect your home’s current system and tell you if copper makes sense for your project.

PEX Pipes: The Flexible Newcomer

PEX stands for cross-linked polyethylene. It’s a type of plastic pipe that’s flexible, easy to work with, and great for repiping jobs in tight spaces.

Pros of PEX:

• Affordability: It’s much cheaper than copper and takes less time to install.
• Flexibility: PEX can bend around corners, which means fewer fittings and joints.
• No Corrosion: PEX won’t rust or corrode, even in areas with hard water.

Cons of PEX:

• UV Sensitivity: PEX can’t be used outdoors because sunlight can damage it.
• Rodents: In rare cases, rodents have been known to chew on PEX pipes.
• Newer Material: PEX hasn’t been around as long as copper, so some homeowners worry about long-term reliability.

At High Speed Plumbing, we’ve seen an increasing number of people choose PEX for their repiping jobs because of its flexibility and cost savings. It’s especially popular in modern homes or in homes where quick installation is needed.

Comparing the Two Side by Side

When it comes to choosing between copper and PEX, here’s a quick side-by-side to help you think it through:

Feature	Copper	PEX
Cost	High	Low
Installation	Labor-intensive	Quick and easy
Lifespan	50+ years	40–50 years
Flexibility	Rigid	Very flexible
Corrosion	Can corrode	Corrosion-resistant
Water Quality	Excellent	Very good
Outdoor Use	Yes	No

So, which one should you choose? It depends on your home’s needs, your budget, and how long you plan to live there. A trusted plumbing service like High Speed Plumbing can evaluate your system and help you decide what works best.

Which Is Better for You?

If you have an older home and want something long-lasting and traditional, copper might be the way to go. It’s strong, trusted, and durable. But if you're looking to save money and time while still getting reliable results, PEX is a great alternative.

Some people even choose to mix the two. PEX can be used inside walls, while copper is used where pipes are visible. This gives you the benefits of both materials.

Before making a decision, always get a full inspection from a licensed plumber. They’ll look at your home’s layout, your current piping, and your water quality to recommend the right solution.
