What Is Repiping and Why It Matters
Repiping means replacing some or all of your home’s plumbing pipes. It can involve just the water supply lines or everything from the main line to the fixtures.
It’s not a last resort. It’s a necessary reset when patching no longer works.
How Long Should Pipes Last? (Lifespan by Material)
Old pipes don’t last forever, no matter how many patch jobs you throw at them.
- Copper pipes: 50 to 70 years
- Galvanized steel: 20 to 50 years
- Polybutylene: 10 to 15 years (if you’re lucky)
- PEX (cross linked polyethylene) and PVC: 40 to 50 years
- Lead: Should’ve been replaced decades ago. Full stop.
13 Clear Signs It’s Time to Repipe Your House
1. Low Water Pressure Across the House
When your shower feels like someone dribbling from a sippy cup, you’ve got problems. Mineral buildup or failing piping materials are usually to blame.
2. Rust-Colored or Yellow Water
If your water looks like weak tea or swamp runoff, it’s not just gross it’s a warning. Corroded steel or iron pipes are leaching into your water.
3. Metallic or Musty Smell in Water
Water shouldn’t taste like pennies or smell like a wet attic. That’s your pipes waving a red flag.
4. Pipes That Are Noisy, Bang, or Whistle
This isn’t a haunted house. Pipes should be quiet. Clanging or hissing means pressure problems or unsecured piping.
5. Frequent Leaks or Recurring Water Damage
A drip here, a stain there—it’s death by a thousand pinholes. At some point, patching becomes a waste of time and money.
6. Mold or Mildew Around Pipes or Walls
If your bathroom smells like a wet towel 24/7, hidden leaks may be feeding mold growth behind your walls.
7. Slow-Filling Tubs, Toilets, or Appliances
This isn’t a faucet problem. Slow fill-ups often point to corroded or blocked pipes.
8. Water Temperature Fluctuations
Your water turns from Arctic to lava in seconds? That’s a symptom of failing mixing valves—or worse, deteriorating supply lines.
9. Old Pipe Materials (Polybutylene, Galvanized, Lead)
If your home was built pre-1995 and never repiped, it likely contains pipe materials that have failed thousands of homes before yours.
10. Visible Corrosion or Flaking on Exposed Pipes
See rust, white crust, or greenish stains? Your pipes are corroding, even if you haven’t spotted a leak yet.
11. Recent Foundation Shifts or Slab Cracks
Movement in your foundation can stress and break old piping. Leaks beneath slabs can cause cracks and swelling.
12. Remodeling a Kitchen or Bathroom
If you’re already opening the walls, this is the cheapest time to repipe. Don’t waste drywall repair on old piping.
13. Your Home Was Built Before 1980
Older homes were often built with now-obsolete materials. If the pipes haven’t been replaced, odds are they’re aging out fast.
What Happens If You Don’t Repipe in Time?
Wait too long and it gets ugly.
You’ll deal with:
- Water damage behind walls and under floors
- Hidden mold that spreads through drywall
- Skyrocketing water bills from constant leaks
- Insurance battles that leave you footing the bill
What’s Involved in Repiping a Home?
Expect 3–5 days for a full repipe project, depending on your home’s size. Plumbers replace old water supply lines with modern options like PEX or copper pipes.
You may need drywall repair where access was cut. Good plumbers minimize wall damage with strategic cuts and reroutes.
Repiping costs vary based on materials, labor costs, house size, and pipe access.
Is It Cheaper to Repipe or Keep Repairing? (Spoiler: Not Really)
Let’s do the math.
Say each leak costs you $300. Now multiply that by five in a year. Add water damage. Add mold treatment. Add drywall repair.
A full repipe might cost $4,000–$8,000 depending on your home and materials used, but you only pay it once.
Repiping is a cost effective long-term fix that also boosts home resale value and efficiency.
Why Water Quality Suffers with Old Pipes
Old pipes break down. That affects your water in nasty ways.
- Lead and copper can leach into your supply
- Biofilm and rust degrade water taste and smell
- Sediment buildup restricts water flow and strains water heaters
You’ll feel it in the shower. You’ll taste it in your coffee. And your plumbing system will be on borrowed time.
When to Call a Plumber vs When It’s Time to Repipe
Call a plumber when you see:
- New leaks
- Discolored water
- Unusual pipe noise
They’ll inspect using cameras and pressure tests. If issues are widespread or materials are outdated, they’ll recommend repiping.
A good quote includes materials, labor, drywall repair, and cleanup. Ask about financing options—many pros offer them.
Repiping FAQs
How long does repiping take?
Most homes take 2–5 days, depending on size and layout.
Can I stay in my house while it’s happening?
Yes. Plumbers usually repipe one zone at a time so you still have running water.
Do I have to replace all the pipes?
Not always. Partial repiping is possible, but it depends on age, materials, and damage.
Will insurance cover it?
Usually no, unless it’s tied to sudden damage. Check your policy.
What’s the best pipe material?
PEX pipes are flexible, affordable, and last 40–50 years. Copper pipes are more durable but cost more.
