Choosing the right pipe for a repipe makes a real difference in cost and how long your plumbing lasts. I install both PEX and copper every week here in the Inland Empire, so let me give you the straight comparison, no sales pitch.
Is PEX or copper cheaper to repipe with?
PEX usually costs less. As a rough guide, PEX repiping runs about $4 to $8 per linear foot installed, while copper runs about $8 to $12 per linear foot. The material is cheaper and it installs faster with less labor and fewer wall openings, so you save on both. Copper costs more upfront because of the material and the soldered joints.
| Factor | PEX | Copper |
|---|---|---|
| Cost per linear foot | $4 to $8 | $8 to $12 |
| Lifespan | 40 to 50 years | 50-plus years |
| Hard-water corrosion | Does not corrode | Can pit and corrode |
| Install | Fast, flexible, fewer wall cuts | Slower, rigid, more labor |
Which lasts longer, PEX or copper?
Both last decades. Modern PEX lasts 40 to 50 years, and copper can last 50-plus years when the water is not too aggressive. The old idea that PEX is a short-life pipe is out of date. For most Inland Empire homes, both are long-term pipes, so lifespan alone is not the thing that decides it.
Does Corona's hard water ruin copper pipes?
Our hard and aggressive water can pit and corrode copper over the years, which is the real local reason PEX often wins here. PEX does not corrode, so it holds up better against the mineral-heavy water in Corona, Riverside, and Norco. That resistance is a bigger deal in our area than in places with soft water.
What about installation differences?
PEX is flexible, so we can snake it through walls with fewer fittings and less demolition. That means a quicker job and less patching afterward. Copper is rigid and every joint is soldered, so it takes longer and usually means more wall openings. If you want the least disruption, PEX is the easier install.
Where does copper still make sense?
Copper is a great pipe and some homeowners simply prefer it. It is naturally resistant to bacteria, it handles high heat well, and some buyers like knowing a home has copper. If that is what you want, we install it and do it right. See our full repipe services.
So which should you actually pick?
For most Inland Empire homes, we recommend PEX because it costs less, installs faster with less damage to your walls, and does not corrode in our hard water. Copper is still a great pipe and we install it when a homeowner prefers it or the job calls for it. We are not here to upsell you, we install what is right for your home.

Can you mix PEX and copper in the same house?
Yes, we do it often. We can tie new PEX into existing copper with the right fittings, which is handy when we only repipe part of a home.
Does PEX change the taste of my water?
No. Modern PEX is made for drinking water and does not change the taste. If anything, getting the old corroded galvanized pipe out of your house makes the water taste and look better.
Does copper add more resale value than PEX?
Not in a way most buyers notice. What matters at resale is that the home has been repiped and no longer has failing galvanized pipe. Buyers care that the plumbing is new and works.
