Signs You Need To Repipe
Most homeowners do not think about their plumbing until something goes wrong. Unfortunately, by the time a pipe fails visibly (a burst line, a water stain on the ceiling, or a flooded cabinet under the sink), the damage is already done. The good news is that failing pipes rarely fail without warning. Here are seven signs that your home’s plumbing may be due for replacement, and what to do if you recognize them.
The 7 Warning Signs
1Rust-Colored or Discolored Water
If your water runs brown, orange, or yellow (especially when first turned on in the morning), that discoloration is rust. In homes with galvanized steel pipes, the interior corrodes over time and that corrosion enters your water supply. Rust-colored water is evidence that your pipes are deteriorating from the inside. If discoloration persists after letting the water run for several minutes, the source is your pipes, not the municipal supply.
2Chronically Low Water Pressure
Mineral deposits, corrosion, and pipe scale accumulate on the interior walls of aging pipes over decades, gradually restricting effective diameter. The result is progressively lower water pressure throughout the home: at the shower, kitchen faucet, and outdoor hose bibs. If you have had your pressure regulator checked and pressure is still low, the problem is almost certainly the pipes themselves. A whole house repipe restores full pressure to every fixture.
3Recurring Pinhole Leaks
One pinhole leak can be a fluke. Two or more in a short period is a pattern that demands attention. Pinhole leaks in copper pipe are typically caused by aggressive water chemistry or microbiologically influenced corrosion. Once pinholes begin forming, they tend to multiply. Each repair you make is a temporary fix on a system that will continue to fail at other points. At some threshold, continued repairs cost more than a complete repipe.
4Visible Corrosion on Exposed Pipes
Check the pipes visible under sinks, in the garage, or in the utility room. What you see on exposed pipe is a reliable indicator of what is happening inside your walls:
- Blue-green staining on copper: active oxidation and corrosion
- White mineral buildup at joints: chronic seeping or slow leakage at fittings
- Flaking or pitting on galvanized pipe: the zinc coating has failed and the steel core is corroding
5Metallic Taste or Smell in Your Water
Elevated iron, copper, or zinc in drinking water is a direct result of pipe corrosion leaching into your supply. If your tap water has a metallic taste or unusual smell that filtered water does not have, request a water quality test. High metal content in drinking water is both a plumbing concern and a health concern. California has established maximum contaminant levels for metals, and corroding pipes are a common cause of residential exceedances.
6Frequent Leaks in the Same Section of Pipe
If you have experienced multiple leaks in the same general area (even after professional repairs each time), the pipe in that section has reached end of life. Localized repairs address individual failure points. Repiping addresses the underlying cause: aged, degraded pipe material that will continue to fail. A useful rule of thumb: if you have spent more than $1,500 on plumbing repairs in the past two years on the same system, a repipe quote is worth obtaining.
7Your Home Was Built Before 1985 and Has Never Been Repiped
This final sign is not a symptom: it is a statistical reality based on the service life of materials used in residential construction during that era:
| Pipe Material | Era Used | Service Life / Status |
|---|---|---|
| Galvanized steel | Pre-1980 | 40–60 year lifespan. Most pre-1980 installations are at or past end of life. |
| Polybutylene | 1978–1995 | Prone to sudden catastrophic failure from chlorine degradation. Subject to national class action litigation. Replacement is overdue. |
| Thin-wall copper (1960s–70s) | 1960–1975 | Higher pinhole failure rate than modern copper. May have corroded fittings even if pipe appears intact. |
If your home has original plumbing from before 1985 and has never been assessed, a free inspection is the appropriate next step.
What to Do If You Recognize These Signs

Frequently Asked Questions About Repiping
How long does a whole house repipe take?
Most single-family home repipes are completed in one to two days. Drywall patching adds one additional day if included. City inspection is typically scheduled within 48 hours of job completion by Repipe Champions Plumbing and Rooter.
Is repiping covered by homeowners insurance?
Standard homeowners insurance policies do not cover repiping as a maintenance item. However, if a pipe failure causes water damage, that damage may be covered depending on your policy. Some insurers offer discounts after a repipe is completed. Check with your insurance provider for specifics.
What is the best pipe material for a repipe?
Both copper and PEX are excellent choices. Copper is the most proven material with a service life exceeding 50 years when properly installed. PEX is flexible, resistant to freezing, and less expensive. Repipe Champions Plumbing and Rooter installs both and will recommend the right material based on your home’s water chemistry, budget, and access conditions.
How much does repiping cost in the Bay Area?
Whole house repiping in the Bay Area typically ranges from $4,500 to $15,000 depending on home size, pipe material selected, and access complexity. Repipe Champions Plumbing and Rooter provides free, no-obligation on-site estimates. Call (408) 295-4309 to schedule yours.
