Copper pipe repair and pinhole leaks
A single pinhole or a split copper pipe is repaired by cutting out the damaged section and soldering or press-fitting a new piece. Repeated pinholes in different places usually mean the pipe is thinning throughout, and replacing those runs is the better value.
Copper lasts a long time, but it can develop pinhole leaks from the inside, often linked to water chemistry, high velocity or poor original workmanship. Green or white crust at a fitting usually marks a slow leak.
One leak is a repair. A pattern of leaks is a warning that the rest of the run is in similar condition.

Copper pipe repair: common questions
Why does my copper pipe have pinhole leaks?
Pitting from water chemistry, high flow velocity, or flaws from installation are common causes.
Are clamp repairs permanent?
Repair clamps are temporary. A proper repair replaces the damaged section.
When should I replace copper instead of repairing it?
When leaks keep appearing in different spots on the same system.
