Referral service, not a contractor. Prevent Home Leaks does not perform plumbing, leak repair, or water damage restoration. We may be paid if you hire a provider through a partner link. Always confirm the provider's license and get a written estimate. How this works
Pinhole leaks in copper pipe
Copper usually lasts a long time, but some homes develop pinhole leaks from localized corrosion inside the pipe. Factors cited include water chemistry, high flow velocity, and installation issues.
Warning signs
- Small blue-green spots or crusty deposits on exposed pipe
- A tiny spray or drip, often found by a damp spot in a wall or ceiling
- Repeated leaks in different spots over a short period
Options
- Spot repair of a single leak is quick and inexpensive.
- Repeated leaks suggest a systemic problem. Ask about water chemistry testing and compare the cost of ongoing repairs against repiping.
- Check pressure too, since high pressure adds stress.
Shut off water to the area as soon as you see a leak (find your shutoff).
