Copper Piping For California Homes: The Guide To Protecting Your Plumbing System
Overview: Copper piping might not seem like the most exciting topic in the world, but trust us, it’s worth getting to know. Copper piping has been in use for centuries, and it has played an important role in the history of plumbing. Discover the ins and outs of copper piping!
Is there anything exceptional about copper? It’s used to make pennies and some old-fashioned cooking pots. But most of the time, you probably don’t think about it very much.
But take a moment to consider copper piping. It might be hidden away behind walls and under floors, but it’s a longtime hero of the plumbing world, with a history that spans centuries and a durability that’s tough to beat.
Copper piping is like an old, reliable car that still runs fine and gets you where you need to go. But it’s even more than that. Copper piping is something of a jack-of-all-trades when it comes to plumbing, and it’s used for everything from water supply lines to gas lines to HVAC systems.
And while it might not have the glamour of other, newer plumbing materials, copper piping more than makes up for it in durability, longevity, and versatility. So buckle up, friends, and get ready to learn about copper piping!
What Is Copper Piping?
Copper piping refers to a type of plumbing pipe made from the metal copper (that’s Cu on the periodic table for those of you who remember your high school Chemistry).
Copper piping is commonly used for water supply lines, as well as for heating, ventilation, and air conditioning (HVAC) systems. Copper piping has long been popular for its durability, resistance to corrosion, and ability to withstand high temperatures and pressure.
Copper piping is also relatively easy to install and maintain, making it a popular choice for residential and commercial plumbing applications.
Why Copper Piping?
Now that we understand the what of copper piping, let’s get into the whys.
Copper is a great conductor of heat and electricity. Because it’s resistant to corrosion, it won’t rust or degrade over time like other metals. Plus, copper is easy to work with — it’s malleable, so you can bend and shape it into all sorts of configurations without it cracking or breaking.
In recent years, PEX pipe has started creeping in on copper’s territory, with many new plumbing installations using PEX pipe for applications that previously would have used copper piping. PEX pipe is a flexible and less expensive option — but copper is still a popular choice for its long-term dependability.
Types of Copper Piping
There are two main types of copper piping:
Rigid copper piping is what you’ll typically see in residential plumbing — it’s thick and sturdy, and it’s designed to be used in fixed locations.
Flexible copper piping, on the other hand, is more commonly used for things like refrigerator water lines and ice makers — it’s thin and pliable, so it can be easily routed around corners and obstacles.
Benefits of Copper Piping
In addition to its heat-resistance and resistance to corrosion, one of the biggest benefits of copper piping is the longevity it offers. Copper pipes can last for decades, and in some cases, they’ve been known to last a hundred years! This means you won’t have to worry about replacing your plumbing anytime soon, which can save you a lot of time and money in the long run.
For this reason, copper piping can be a selling point if the time comes when you decide to sell your home.
What to Expect During a Whole-Home Copper Repipe
A copper repipe is a precise, step-by-step process handled by licensed professionals.
Here’s what typically happens:
1. Inspection and planning
Technicians inspect your existing plumbing, test water pressure, and map the most efficient new layout.
2. Preparing your home
Surfaces are covered and protected. Water is turned off only for short periods during installation.
3. Installing new copper lines
Old pipes are replaced with Type L copper tubing, routed through walls, ceilings, or attics, depending on your home’s structure.
4. Wall repair and finishing
Once the new lines are installed, all access points are patched, textured, and cleaned — no unfinished drywall left behind.
5. Final testing and inspection
Every new line is pressure-tested and inspected to meet California building standards. For a closer look at each step, our repiping process overview explains what happens from start to finish.
How Much Does Copper Repiping Cost in Southern California?
Copper repiping costs vary depending on your home’s layout, access, and existing pipe condition, but several key factors affect pricing:
- Home size and fixture count: larger homes require more materials and labor
- Foundation type: slab foundations are more complex than crawlspaces
- Number of stories: multi-level homes require longer pipe runs
- Finishing work: drywall patching and texturing after installation
While it’s a significant investment, copper repiping improves both property value and water quality for decades. You can find a detailed pricing overview in our California copper repipe cost guide.

Frequently Asked Questions
How long does a copper repipe usually take in Southern California homes?
Most single-family homes can be repiped in one to two days, depending on layout and size. Slab foundations may take slightly longer due to limited access.
Will my water taste or look different after a copper repipe?
Yes, for the better. New copper lines deliver cleaner-tasting water and eliminate discoloration from internal corrosion (if you were experiencing this issue).
Can you repipe just part of a home instead of the entire system?
Yes. Partial repiping works when only one section (like a bathroom or kitchen) is affected. However, full repiping is often more cost-effective for older systems.
What should I do to prepare my home before a repipe starts?
Clear access around sinks, showers, and water heaters. Cover valuables and coordinate with your plumber about short water shutoffs.
Do copper repipes increase home value in Southern California?
Not necessarily. But that doesn’t mean you shouldn’t do it. Repipes are seen as a necessary improvement in a home rather than a value booster since having a properly working pipe system is essential for a functional home. If your home has outdated plumbing at the time of sale, that could be a turnoff for some buyers.
