If your home has aging or damaged pipes, repiping is one of the smartest investments you can make to protect your plumbing system and water quality. But once you decide to repipe, another important decision comes next: Should you use copper or PEX piping?
Both materials are widely used and trusted, but they offer different advantages depending on your home, budget, and long-term goals. Our team at Service Plumbing & Heating breaks down the differences between copper and PEX so you can make the best choice for your home.
Why Homeowners Repipe Their Homes
Before comparing materials, it’s helpful to understand why repiping may be necessary in the first place. Common reasons include:
- Frequent pipe leaks or corrosion
- Low water pressure
- Discolored or bad-tasting water
- Outdated materials like galvanized steel or polybutylene
- Major remodeling or plumbing upgrades
Whether you’re experiencing plumbing problems or planning a proactive upgrade, repiping ensures safer, more efficient water flow throughout your home.
What Is Copper Piping?
Copper has been a standard plumbing material for decades. It’s known for its durability, longevity, and resistance to UV rays and bacteria.
Benefits Of Copper Piping:
- Long lifespan – Can last 50+ years when properly installed
- Corrosion-resistant – Ideal for clean water delivery
- Heat and pressure tolerant – Performs well in high-stress systems
- Fire-resistant – Won’t burn or emit toxic fumes during a fire
- Rigid and durable – Less prone to physical damage
Other Considerations:
- Higher cost – Material and labor costs are significantly higher than PEX
- Labor-intensive installation – Requires soldering and more wall access
- Can corrode in certain soil or water conditions
- Not as freeze-resistant – Can burst more easily if frozen
What Is PEX Piping?
PEX (cross-linked polyethylene) is a flexible plastic tubing that has become increasingly popular for residential repiping projects.
Benefits Of PEX Piping:
- Flexible and easy to install – Great for tight spaces and remodels
- Lower material and labor costs – More budget-friendly overall
- Freeze-resistant – Can expand without bursting
- Corrosion-proof – Not affected by acidic water or soil
- Quiet operation – Reduces “water hammer” noise in the system
Other Considerations:
- Not UV resistant – Can’t be used in direct sunlight or exposed areas
- Shorter track record than copper – But strong performance so far
- May not be allowed in all jurisdictions – Always check local code
- Can be chewed by rodents – More vulnerable if not well-protected
Which Piping Material Is Right for Your Home?
The right choice between copper and PEX depends on a few key factors:
1. Budget & Project Scope
If you’re looking for a cost-effective solution and want faster installation, PEX is typically the better choice—especially for full-home repiping or remodels. It reduces labor time and material costs significantly.
If your budget allows and you’re focused on long-term durability, copper may be the better investment, particularly in homes where it’s already in use or when resale value is a consideration.
2. Local Water Quality & Environment
PEX handles acidic or hard water better than copper. If your area has known water quality issues, PEX may be less likely to corrode or degrade over time.
3. Existing Plumbing System
If your home already has copper plumbing in good condition, it may make sense to stick with the same material for consistency and compatibility.
4. Code Requirements In Your Area
Some building codes may restrict or regulate the use of PEX. Our team is familiar with Lynnwood’s local codes and can help you choose a material that complies with all regulations.
