What Is the Average Lifespan of Copper Pipes in a House?
Copper water pipes usually last 50 to 70 years. That range comes from home inspection life expectancy charts. Your pipes may last longer or fail sooner, depending on a few things.
What Changes How Long Copper Lasts
Not all copper is the same. Copper pipe comes in three main types, and the difference is wall thickness.
Thinner walls leave less metal to wear through over time. Water chemistry matters too. Research shows a water's pH can affect how fast copper pits from the inside. How well the pipes were installed also plays a part.

Not all copper is the same. Copper pipe comes in three main types, and the difference is wall thickness.
| Type | Wall Thickness | Where It's Used |
|---|---|---|
| Type K | Thickest | Underground water lines |
| Type L | Medium | Homes and commercial buildings |
| Type M | Thinnest | Above-ground lines in homes |

How to Find the Age of Your PipesStart with the year your home was built. You can find it on your county assessor's records or your home inspection report. If the plumbing was ever replaced, your inspection report or past repair invoices may show it.
Compare your pipes' age to the 50 to 70 year range. Then check for the warning signs in the next section. Age alone doesn't mean you need new pipes, but age plus problems usually does.

How to Tell If Copper Pipes Need to Be Replaced: 7 Warning Signs
Copper pipes give clear signs when they start to wear out. Most of these you can check yourself in a few minutes. Here's what to look for.
- Pinhole leaks. These are tiny holes that drip or spray. Researchers estimate about 750,000 pinhole leaks happen in U.S. homes each year (source). When one shows up, others are often forming in the same pipe.
- Blue-green stains. Health officials note that blue-green stains on sinks, tubs, or laundry can point to high copper in your water.
- Metallic or bitter taste. The CDC notes a metallic taste can be a sign of too much copper in your water (source).
- Crust or flaking at joints. Green, white, or blue buildup on fittings can point to corrosion or a slow leak.
- Low pressure in several spots. One weak faucet may be a clogged aerator. Weak flow at several faucets can mean a blockage or leak in the pipes.
- Leaks that keep coming back. If you've patched a pipe and keep finding new leaks, the pipes are likely breaking down.
- Pipe age. Copper close to 50 years old or older is near the end of its normal life.
How to Check for a Hidden Leak With Your Water MeterYour water meter can tell you if water is leaking where you can't see it.
- Turn off every faucet, toilet, and water appliance in your home.
- Write down the number on your water meter.
- Wait one to two hours without using any water.
- Check the meter again.
Do Green Copper Pipes Need to Be Replaced?
Not always. Copper naturally turns blue-green when it's exposed to air and water. What matters is where the green shows up and what it feels like.
Normal Aging vs. a Problem
Here's what we look for when we check green spots on copper.
Normal Aging vs. a Problem
Here's what we look for when we check green spots on copper.
| Normal Aging | Likely a Problem | |
|---|---|---|
| Where you see it | Evenly along the pipe | Bunched at joints and fittings |
| How it feels | Dry and smooth | Damp, crusty, or flaky |
| Does it come back? | Stays the same | Returns after you wipe it off |
| What it means | Surface color change | A slow leak or worn pipe |
Try the Wipe TestDry the spot with a paper towel. Wipe it clean, then check it again in a few days. If the area stays dry and the green doesn't return, it's likely normal aging. If it's wet, crusty, or comes back, you probably have a slow leak.
When Green Spots Mean Call NowCall a plumber if you see green at a joint along with dampness, drips, or water stains nearby. Leaks from old pipes can soak into drywall and lead to mold. We can find hidden leaks in your home and tell you if it's one fitting or a bigger problem.
When Should I Repipe My Copper Pipes Instead of Repairing Them?
Repair the pipe if you have one leak in an otherwise healthy system. Think about repiping once leaks keep coming back. Here's how to tell which side you're on.
| Repair If... | Repipe If... |
|---|---|
| You have one leak in one spot | You've had two or more leaks in a year |
| The rest of your pipes look clean and dry | You see corrosion at several joints |
| Your water pressure is normal | Pressure is low at several faucets |
| Your pipes are well under 50 years old | Your pipes are near or past 50 years old |
The Real Cost of Patching Again and AgainEach repair has its own service call, labor, and drywall patch. Those costs add up fast when leaks keep showing up. National cost data from Angi puts a full repipe between $1,500 and $15,000, with most homeowners paying around $7,500. About 70% of that cost is labor.
Your price depends on your home's size, number of fixtures, pipe material, and how easy the pipes are to reach. We give you a clear quote before we start. We also offer financing on every job.

Water Damage Adds to the BillA slow leak inside a wall can soak wood, ruin drywall, and lead to mold. By the time you see a stain, the damage underneath is often bigger. Those repairs come on top of the plumbing work.
Selling Your Home Soon?Old, leaky pipes can cause problems at inspection. New pipes can help your home pass and make buyers more likely to make an offer.
Copper Under a Slab Needs Fast AttentionMany homes have copper water lines running under the concrete slab. Pipes under concrete are harder to reach, so repairs there cost more. Watch for warm spots on the floor, the sound of running water, or a water meter that moves when nothing is on. If you notice any of these, we offer slab leak repair in Little Rock and can find the leak without guessing.
Is It Worth Replacing Copper Pipes With PEX?
For many homes, yes. PEX costs less and installs faster, which lowers the price of a repipe. Copper still has its place, though, so it helps to know the tradeoffs.
Cost figures are national averages from Angi. Life expectancy comes from home inspection charts.
Not sure which material fits your home? We'll look at your setup and walk you through your options for copper pipe replacement.
| PEX | Copper | |
|---|---|---|
| Material cost | About $0.40 to $2 per foot | About $2 to $8 per foot |
| Install | Flexible, fewer joints, faster | Rigid, more fittings, more labor |
| Freezing | Less likely to burst | Can burst if it freezes |
| Sunlight | Breaks down with UV exposure | Not affected by sunlight |
| Expected life | Around 40 years | Around 50 to 70 years |
Cost figures are national averages from Angi. Life expectancy comes from home inspection charts.
Where PEX Works BestPEX bends around corners, so we can run it through existing walls with fewer openings. The Plastics Pipe Institute notes that fewer joints mean fewer places for leaks to start. It also holds up better when a cold snap hits.
PEX can't sit in sunlight. UV light weakens it over time, and the damage isn't visible. Any PEX in a sunny spot needs a UV-blocking sleeve or cover.

Do Plumbers Still Use Copper?Yes. Copper is still a solid choice, and many homes in Little Rock run on it today. PEX has simply become the more common pick for full repipes because it saves on labor.
PEX Under Your SlabArkansas law allows PEX for water lines under concrete slabs. It has to meet specific national standards for that use. That matters if your old copper runs under your foundation and needs to be replaced.

Will Insurance Pay to Repipe a House?
Usually not. Homeowners insurance doesn't pay to fix or replace pipes that wore out with age. Your policy may still help with the water damage a sudden leak causes.
When we find a leak, we tell you what caused it and put it in writing. That gives you clear facts to share with your agent.
What's Usually CoveredAccording to the Insurance Information Institute, a standard HO-3 policy covers:
- Water that suddenly and accidentally leaks from your plumbing
- Damage from frozen pipes
- Repairs to floors, walls, and belongings hurt by a covered leak
What's Usually Not Covered
- Fixing or replacing the pipe that caused the leak
- Pipes that wore out or corroded over time
- Slow leaks the insurer sees as a maintenance issue
Older Homes and InsuranceSome insurers want proof of plumbing updates on older homes. One Arkansas homeowners policy, for example, requires updated plumbing on homes over 50 years old. Insurers mostly flag galvanized, polybutylene, and lead pipes, not copper. Still, a copper system with repeat leaks can raise questions at renewal.
How to Protect Your Claim
- Take photos of the leak and the damage before cleanup.
- Keep every repair invoice and past inspection record.
- Ask your plumber for a written report on the cause.
- Call your insurance agent with those details in hand.

Why Little Rock Homeowners Call Us
Older Homes in Hillcrest, the Heights, and MidtownIf you own an older home in Hillcrest, the Heights, or Midtown, your plumbing may be original. If your home has never been repiped, your copper may be near the end of its life.
Slab Homes in Pleasant Valley and West Little RockIf your home in Pleasant Valley or west Little Rock sits on a concrete slab, copper lines may run underneath it. A leak there can stay hidden until you feel a warm floor or see a moving meter.
Clay Soil and Your PipesThe Arkansas Geological Survey notes that parts of our state have clay soils that swell when wet and shrink when dry. That movement can crack foundations. Shifting clay can also stress buried water lines over time.
What Our City Water Tells YouOur water comes from Lake Winona and Lake Maumelle through Central Arkansas Water. Their latest water quality report shows copper levels at the tap well below the federal limit. Most copper in drinking water comes from home plumbing.

Common Questions
Most homes only need to replace copper pipes once every 50 to 70 years. There's no set schedule. Replace them when they reach that age range and start showing signs like repeat leaks or corrosion.
Yes, if the problem is limited to one area. Replacing one section costs much less than a whole-house repipe. If leaks keep showing up in different spots, a full repipe usually makes more sense.
Most repipes take a few days for smaller homes. Larger homes with more bathrooms and fixtures can take longer. We give you a timeline before we start so you can plan around it.
