Copper Repiping
Copper repiping replaces old supply lines with new copper pipe, the traditional premium material prized for its durability and long service life. Copper resists UV damage, handles high temperatures, and has a proven track record spanning generations. FlowFast connects you with an independent local plumber skilled in copper repiping for your home.

Whole-Home RepipingFrequent leaks or rusty water? Signs your home needs repiping, copper vs. PEX, and how to get connected with an independent local plumber.
View all Repiping servicesCopper has been the benchmark plumbing material for the better part of a century, and it earned that reputation in millions of homes. It stands up to sunlight, high heat, and physical impact in ways plastic pipes cannot, and properly installed copper routinely serves for fifty years or more. For homeowners who want the longest-lasting option and do not mind the higher material cost, copper remains the gold standard for repiping.
Not all copper is equal, and neither is all household water, so both choices deserve attention. Type L copper has thicker walls than Type M and is the better choice for repiping, while aggressive or acidic water can cause pinhole leaks even in copper over time. Soldered joints require real craftsmanship to be clean and reliable for decades. FlowFast connects you with an independent local plumber who will check your water chemistry, use quality Type L copper and lead-free solder, and pressure-test the finished system thoroughly.
Warning signs
Signs you need this service
- You want the longest-lasting repipe material and are willing to invest in a premium installation done right.
- Existing copper has developed pinhole leaks from aggressive water, and a full replacement beats patching them one by one.
- Pipes run through sun-exposed areas where plastic piping would need extra shielding from harsh UV exposure.
- You are restoring or upgrading a home and want plumbing that matches its long-term value and quality.
What to expect
The process, step by step
The pro assesses your water chemistry and plans copper routes, usually in Type L for thicker walls.
Old piping is disconnected as new copper is cut, fitted, and soldered run by run throughout.
Every joint is cleaned, fluxed, and soldered with lead-free solder, then the whole system is pressure-tested for leaks.
Fixtures are reconnected, lines are flushed completely clean, and the pro verifies pressure and water clarity.
Prevention
How to avoid this problem
- Have water tested for acidity, since low-pH water can pit even new copper over time.
- Keep water pressure moderate with a regulator to extend the life of joints and pipe walls.
- Insulate hot copper lines to reduce heat loss and protect against condensation in humid spaces.
