PEX vs Copper Repiping: Key Differences
When you repipe a home, the choice is usually
PEX or
Copper Type L. Both are proven. The right fit depends on cost, access, water quality, exposure, and local code.
Why Homeowners Choose PEX Piping
- Lower leak risk. PEX resists pinhole leaks common in aging copper.
- Freeze resistant. Expands in freezing conditions to reduce burst risk.
- Cost savings. Often about 25 percent less than copper due to faster installs and lower material cost.
- Flexible. Bends through tight spaces and long runs with fewer fittings.
- Corrosion resistant. Unaffected by most soil conditions and water chemistry.
Benefits of Copper Type L Piping
- Longevity. Properly installed systems can last 40 to 60 years.
- High heat resistance. Handles very hot water and mechanical rooms well.
- Fire resistant. Non combustible for fire prone areas.
- Structural strength. Rigid and durable for exposed runs.
- Proven track record. Decades of reliable use in homes and buildings.
Cost Comparison
- PEX repiping. Typically about 25 percent less due to speed and material.
- Copper Type L repiping. Higher upfront cost, sometimes preferred for specific codes or exposed areas.
Which One Should You Choose
- Choose PEX for a cost effective, flexible, corrosion resistant, and fast install solution.
- Choose Copper Type L for a rigid, time tested material with high heat resistance and UV tolerance outdoors.
