If a pipe bursts in your Princeton home, close the main water valve first, then turn off breakers near the water. A plumber can replace the broken section and check older pipes nearby. Call the number on this page to be connected with a local plumber in Princeton.

Princeton conditions
Princeton sits on US 70 between Selma and Goldsboro in eastern Johnston County. About 57% of its homes were built before 1980 and the median is 1977. Homes that age may have galvanized steel or early copper supply lines, often patched over the years. Those older materials and the many joints between them are where a freeze usually finds a weak spot.
In-town homes are on Town of Princeton water. Rural parts of the 27569 ZIP, which is several times the size of the town, are a mix of Johnston County water and private wells. If you're on a well, turn off the pump at its breaker along with the house valve.
Published Town information doesn't say where its service line responsibility ends or which office handles plumbing permits. If water is coming up near your meter or the street, call Town Hall first. For permits, ask the plumber; Johnston County Inspections is the likely office, but confirm.
Repair or replace
| Pipe condition | Likely approach | Why |
|---|---|---|
| Sound pipe, one freeze crack | Cut out and replace the section | The rest of the line is fine |
| Galvanized with rust inside | Replace a longer run | Splicing into weak pipe often fails |
| Several breaks along one wall | Replace and insulate the run | Fixes the exposure, not just the crack |
| Old steel throughout | Discuss repiping | Breaks tend to repeat |
Signs of a burst pipe
- Water spraying or dripping
- Rusty water after a pressure drop
- Wet ceilings, walls or floors
- Running water sounds with nothing on
- Standing water or soaked insulation in the crawl space
- A wet patch in the yard between the meter and the house
Rusty water by itself can have other causes, but rusty water together with lower pressure inside the house often points to failing galvanized pipe.
Seasonal notes
Hard freezes cause most bursts. Insulate crawl space pipes, close foundation vents, and disconnect hoses before winter. Leaks often appear as the pipe thaws, so check under the house the day after a hard freeze. In a 1970s home, the crawl space run under the kitchen and bathrooms on an outside wall is the most common trouble spot. If you'll be away, keep the heat on in the mid-50s or higher, and for a long absence shut off the main and drain the lines. On a well, turn off the pump before you leave.
