How do you know a repair is enough and a replacement is not needed?
A repair makes sense when the failure is a single, localized event on a line that is otherwise the right size and made of sound material. Copper develops pinhole leaks from age and water chemistry, but a copper line with one pinhole and no other history is usually a repair. Galvanized steel corrodes from the inside out along its whole length, so a leak in galvanized pipe is a sign the rest of the run is close behind it, which points toward replacement instead.
- A single leak in copper or PEX with no other history usually gets repaired
- Galvanized pipe with one leak often has corrosion throughout the run
- Freeze damage is typically localized to an exposed section near an exterior wall
- A repair does not fix undersized pipe if the real complaint is low pressure everywhere
Signs you have a water line leak worth checking
- A hissing or running water sound near the meter or under a slab
- A specific wet spot in the yard rather than general dampness
- Pressure that dropped after a cold snap
- A visible pinhole spray or green corrosion on exposed copper

What a water line repair includes
- Leak location using pressure testing and, where needed, acoustic tools
