Water Line Repair & Replacement in Wilmington, NC
Low pressure throughout the whole house, or no water at all, often traces back to the buried line bringing water onto the property. It's not necessarily anything inside the house.
The water service line runs underground from the CFPUA meter or curb stop to the house, and it's a different system entirely from the interior supply plumbing covered on our repiping page. A problem here affects the whole house at once, since every fixture depends on this single line.
Most water line calls involve one of two symptoms. Either a sudden loss of water pressure or a complete outage affecting the entire house, or a wet, unusually green patch of yard along the line's likely path that suggests a leak underground.
Why Wilmington's water lines fail the way they do
Older galvanized water service lines, common in homes built before the 1990s near downtown Wilmington, corrode from the inside over decades. The internal diameter narrows enough to noticeably reduce pressure, often years before an actual leak develops.
Sandy coastal soil that shifts with seasonal moisture, the same movement that stresses interior pipe joints, can also crack or separate a buried service line's joints over time, independent of the corrosion pattern affecting older galvanized material specifically.
Signs the water line itself is the problem
- Sudden loss of water pressure throughout the entire house, not just one fixture.
- No water at all, with the meter confirming water is available at the street.
- An unusually wet or green patch of yard along the line's likely path, even without recent rain.
- A water bill increase with no leak found inside the house.
- Discolored water at every fixture at once, suggesting corrosion in the main line itself.
How we diagnose a water line problem
We confirm the issue is actually the service line and not something inside the house first, checking pressure at the meter versus at an indoor fixture to isolate where the drop occurs.
For a suspected leak, acoustic detection equipment traces the sound along the buried line's path, narrowing the location before any digging starts.
For a pressure loss without an active leak, the likely cause is internal corrosion narrowing an older galvanized line, which points toward replacement rather than a repair that wouldn't address the underlying material issue.

Repair vs. replacement
| Situation | Usual approach | Why. |
|---|---|---|
| A single leak in an otherwise sound line | Spot repair | Targeted fix without replacing a line that's otherwise performing fine. |
| Gradual pressure loss from internal corrosion | Full line replacement | A repair doesn't restore the diameter lost to internal corrosion along the whole line. |
| Multiple recent leaks on an aging line | Full line replacement | A pattern of failures usually means the material itself, not one spot, is the problem. |
What affects the price
- Repair of a single leak versus full line replacement.
- Length of line between the meter and the house.
- Trenchless versus open-cut method, depending on access and soil conditions.
- Landscaping or driveway restoration after the work.

What we won't do
We won't recommend replacing the whole service line for a single, isolated leak the camera and pressure testing show is a one-time issue.
If low pressure turns out to be caused by something inside the house, a fixture issue or an interior repiping need, rather than the service line, we'll say so and point you to the right fix instead.

Water line questions from Wilmington homeowners
The water line is the buried service line from the meter to the house. Repiping covers the plumbing inside the house itself. They're separate systems with separate repairs.
It's often the service line itself, especially an older galvanized line narrowing from internal corrosion, rather than an issue with any single fixture.
Not always. Trenchless methods can often repair or replace a line with far less excavation than a traditional open-cut approach, depending on soil and access.
We can test to isolate that. Generally, everything from the meter to the house is the homeowner's responsibility, while the utility maintains the line up to the meter.
It varies by policy and cause. Sudden failure is more likely to be considered than gradual corrosion. Check your specific policy.
