When repiping a home, the choice often comes down to two common materials: copper and PEX (cross-linked polyethylene). Both have unique benefits and drawbacks, and the best choice depends on your home's specific needs and water quality.
PEX – Pros & Cons
- Pro: More cost-effective to install, making it budget-friendly.
- Pro: Flexible and easy to maneuver around tight spaces, reducing installation time.
- Pro: Excellent resistance to corrosion, especially in areas with more acidic water.
- Pro: Fewer fittings are required, which means fewer potential leak points.
- Con: Generally doesn’t last as long as copper pipes.
- Con: Flow could be slightly restricted depending on the fittings used.
- Con: Not recommended for outdoor use or exposure to UV light.
Copper – Pros & Cons
- Pro: Can last significantly longer than PEX if the water quality is good.
- Pro: Environmentally friendly and fully recyclable.
- Con: Installation costs more due to material price and labor intensity.
- Con: Susceptible to corrosion if your water is very hard or acidic, which some Minneapolis and St. Paul water sources are known for.
- Con: Pipes are prone to freezing in colder climates if not properly insulated.
