PEX vs. Copper: Which Repiping Material Is Best for Your Home?
If you’re considering repiping your home, one of the biggest decisions you’ll face is choosing the right material: PEX or copper? Both options have their advantages, but the best choice depends on your budget, home’s needs, and long-term goals. In this guide, we’ll break down the key differences between PEX and copper piping to help you make an informed decision.
What’s the Difference Between PEX and Copper Piping?
PEX (Cross-Linked Polyethylene) Pipes
PEX is a flexible, plastic-based piping material that has become the #1 choice for modern repiping due to its affordability, durability, and ease of installation.
✔ Corrosion-Resistant – Won’t rust or corrode like metal pipes.
✔ Flexible & Easy to Install – Can be bent around corners, reducing the need for fittings.
✔ Cost-Effective – Generally cheaper than copper in both materials and labor.
✔ Resistant to Freezing – Expands slightly under pressure, reducing burst risk.
✔ Quiet Operation – Eliminates “water hammer” noise common in metal pipes.
Potential Drawbacks:
Slightly less heat-resistant than copper.
Cannot be exposed to direct sunlight for extended periods.
Requires special fittings for connections.
Copper Pipes
Copper has been the traditional standard for home plumbing for decades due to its strength and long lifespan.
✔ Extremely Durable – Can last 50+ years under ideal conditions.
✔ Heat & UV Resistant – Can be used for both indoor and outdoor applications.
✔ Proven Track Record – A time-tested plumbing material.
Potential Drawbacks:
Higher Cost – More expensive than PEX in both material and labor.
Corrosion Issues – May degrade over time in areas with acidic water.
Prone to Freezing – Can burst if water inside freezes.
More Fittings & Soldering Required – Increases labor costs and complexity.
Which One Is Best for Your Home?
Both PEX and copper have their strengths, but PEX has become the preferred choice for whole-home repiping due to its affordability, durability, and flexibility. Copper remains a solid option for those who prefer a time-tested material with strong heat resistance.
For most Houston homeowners, PEX is the superior choice for repiping due to its lower cost, faster installation, and resistance to corrosion—especially in areas with hard or acidic water.
