Copper Repiping in Los Angeles
Power Pro Plumbing, Heating & Air repipes Los Angeles and Orange County homes, replacing corroding galvanized steel supply lines with new copper or PEX to end rusty water, weak pressure, and recurring leaks.
Power Pro Plumbing has repiped Southern California homes for more than two decades. A whole-house repipe replaces your aging supply lines with new copper — durable, rust-proof, and time-tested — or with PEX, a flexible modern alternative that can save time and money in many homes. We'll walk you through both options honestly.
A repipe is also the definitive fix for recurring slab leaks: rather than chasing pinholes under the foundation one by one, rerouting new lines overhead ends the cycle for good. Free estimates, upfront pricing, and financing options are available on every repipe.
What are the signs your home needs repiping?
Several of these symptoms together usually mean your home needs repiping; one alone might just be a repair:
- Rusty, brown, or metallic-tasting water — especially first thing in the morning
- Low or steadily declining water pressure throughout the house
- Repeated leaks or slab leaks in different locations
- Visible corrosion on exposed pipes in the garage, attic, or under sinks
- Original galvanized piping in any home more than 50 years old
Copper or PEX: which is better for repiping?
Copper wins on longevity, while PEX wins on cost and speed. Copper doesn't rust, resists SoCal's hard water well, and routinely lasts 50+ years. PEX costs less, installs faster with less wall opening, and its flexibility is genuinely useful in earthquake country. Many repipes sensibly mix both: PEX for long runs, copper for exposed stub-outs.
We'll quote both options for your home so you can weigh cost against preference — either way, the work is permitted, inspected, and pressure-tested.
What does a whole-house repipe involve?
A typical single-family repipe takes a few days: we map the system, open access points in walls and ceilings, run the new piping, connect fixtures, pressure-test everything, and coordinate the city inspection. Water is on each evening, and drywall patching brings the walls back when the plumbing is signed off. We plan the job so your household keeps functioning throughout.
Copper Repiping FAQs
How do I know if my pipes are galvanized? +
Check exposed piping in the garage, attic, or under sinks: galvanized steel is gray, threaded at the joints, and often shows rust at connections. A magnet sticks to it (it won't stick to copper). Homes built before about 1970 that haven't been repiped almost certainly have it somewhere.
How long does a whole-house repipe take? +
Most single-family homes take two to five days of plumbing work, depending on size and access, plus follow-up drywall patching after inspection. You'll have water service restored each night.
Is PEX as good as copper? +
PEX is an excellent, code-approved material with real advantages — lower cost, faster installation, fewer wall openings, and flexibility that tolerates ground movement. Copper still wins on proven longevity and is unaffected by UV. We install both and will recommend what genuinely fits your home and budget.
Will repiping fix my low water pressure? +
If the cause is corroded galvanized pipe narrowing from the inside — the most common culprit in older homes — then yes, dramatically. New piping restores full flow to every fixture at once.
