Copper vs. PEX Piping: Which is Best for Your Home?
If your plumbing is showing its age, you’re probably looking at a full repipe. But before the work begins, you’ll need to choose between two popular piping materials: copper and PEX. Each has its pros and cons—and the right choice depends on your home, budget, and long-term goals.
Let’s break down the differences and help you decide what makes the most sense for your plumbing upgrade.
How to Repipe with PEX
If you’re wondering how to repipe with PEX, it’s all about flexibility—literally. PEX (cross-linked polyethylene) is a flexible plastic piping material that can be snaked through walls, around corners, and into tight spaces with minimal cutting.
The repiping process typically looks like this:
- Turn off the water and drain the system
- Cut and cap old plumbing lines
- Run new PEX lines through access points in walls, ceilings, or under floors
- Connect the PEX system to existing fixtures and the main supply
- Test for leaks and patch up access points
PEX repiping is often quicker and less invasive than copper, making it a popular option for homes with tricky layouts or for projects that need to stay on budget.
How Long Does It Take to Repipe a House with PEX?
On average, how long does it take to repipe a house with PEX? Most homes can be fully repiped in 1 to 3 days, depending on the size of the home and the accessibility of the plumbing system.
Because PEX is easier to work with, it typically shaves hours (or even days) off the installation time compared to rigid copper piping. That means less disruption and faster results.
How Long Does Copper Repiping Take?
Now, how long does copper repiping take? Copper repiping usually takes about 3 to 5 days for a standard home. The process involves cutting into walls, carefully routing rigid copper tubing, and making precise soldered connections.
While copper takes longer to install, many homeowners appreciate its long-standing reputation for durability, heat resistance, and water quality. It’s a great choice if you’re looking for a time-tested, high-performance system.
Copper vs. PEX: Pros and Cons
Here’s a quick comparison to help you decide:
Feature | Copper | PEX |
|---|---|---|
Durability | Extremely durable, lasts 50+ years | Also long-lasting, around 40–50 years |
Flexibility | Rigid—requires more wall access | Flexible—easier to install |
Cost | Higher upfront cost | More affordable overall |
Installation Time | Slower (3–5 days) | Faster (1–3 days) |
Water Quality | Naturally antimicrobial | May absorb odors in some water systems |
Corrosion Resistance | Excellent | Excellent |
Which Is Best for Your Home?
Both materials are safe and reliable—but your decision might come down to your priorities. If you’re after a traditional, high-performance system and don’t mind the extra cost, copper is a solid investment. If you want a faster, less invasive install at a lower price point, PEX is a smart choice.
