Why Homeowners Choose Copper
Copper has carried drinking water in American homes for generations, and it is still the material many homeowners ask for by name. A new copper system is a long-term upgrade for the whole house.
- Rigid metal pipe that holds its shape and looks finished on exposed runs in a garage, basement, or utility wall
- Handles heat and direct sunlight, so it works on outdoor runs and next to the water heater
- Rodents cannot chew through it in attics and crawl spaces
- Matches the rest of the system in homes that are already plumbed in copper
- A material buyers and home inspectors recognize when the house goes up for sale
Comparing materials before you decide? Our PEX repiping page explains the alternative. This page covers what a copper repipe involves.

What a Copper Repipe Involves
A copper repipe replaces every pressurized supply line in the house: the runs to sinks, showers, tubs, toilets, the water heater, laundry, and hose bibs. Drain and sewer lines are a separate system and are not part of this job.
More Access, Planned Ahead
Copper comes in straight lengths, and every change of direction needs a fitting. That means more wall and ceiling openings than a PEX job. We map each run before we start so the openings land where they are easiest to close, and the patch scope is written into your estimate.
Lead-Free Joints
Federal law has required lead-free solder on drinking water lines since 1986. Every joint we make on a supply line meets that rule, and the whole system is pressure tested before any wall is closed.
Bonding and the Water Heater
In many older homes the metal water pipe is part of the electrical grounding path. When we replace it, we restore that bond, and our in-house electrician handles it if the panel side needs work. At the water heater we install dielectric connections so the copper and the steel tank do not corrode each other.

Copper Repiping Questions, Answered
- How long does a copper repipe take?
It depends on the size of the house and the number of fixtures. You get the schedule in writing with your estimate, and we restore water at the end of each workday.
- How long does copper pipe last?
It lasts for decades. Copper supply pipe is commonly expected to serve 50 years or more in normal household use. Water chemistry and installation quality affect that number, which is why we use lead-free joints, dielectric connections at the water heater, and a full pressure test.
- Can you repipe only part of the house in copper?
Yes, we can. When one area has failed and the rest of the system is sound copper, a partial repipe keeps the whole house on one material.
- Can you mix copper and PEX in the same house?
Yes, we can. We join the two with transition fittings approved for the purpose. It is common in partial repipes and in homes where only exposed runs need to stay copper.
- Do I need a permit for a copper repipe?
Yes, you do. A repipe goes through the City’s Building Division, and the inspector checks the pressure test before the walls are closed. We file the permit and meet the inspector under our license.
- Will new copper pipe change the taste of my water?
No, it should not. Properly installed copper does not change the taste of normal tap water. If water sits in the lines overnight, running the tap for a few seconds clears any faint metallic note.
