In Princeton, commercial plumbing mostly means repairs in older buildings: drain and sewer clogs, restroom fixtures, water heaters and supply lines. The Town runs its own wastewater plant, which is being expanded with federal funding now that a state sewer moratorium has been lifted. Call the number on this page to be connected with a local plumber in Princeton.

Princeton's local conditions
Princeton is a small eastern Johnston County town on US 70 between Selma and Goldsboro, incorporated in 1861 as Boon Hill and renamed in 1873. Its housing is mostly older, with a median build year of 1977 and about 57% predating 1980, and the commercial buildings along US 70 and in town tend to match.
The Town bills water and sewer at Town Hall. Its wastewater plant currently treats 275,000 gallons per day and discharges to the Little River in the Neuse Basin. USDA awarded a $10.56 million grant and a $2.4 million loan to expand the plant, and the Town says the state has lifted its sewer moratorium. For a business planning to build or expand, that's the key local fact: ask the Town about connection timing before finalizing plans.
Which system sells the Town its water wasn't confirmed in our research, though Johnston County lists a "Princeton Kenly" water district for unincorporated areas. Rural addresses in the 27569 ZIP may be on county water or private wells.
Repair or replace in an older building
| Item | Repair often works when | Replacement makes sense when |
|---|---|---|
| Drain line | A clog clears and the pipe looks sound on camera | Breaks, sags or roots keep causing backups |
| Supply piping | A single leak on otherwise good pipe | Galvanized pipe is restricting flow throughout |
| Water heater | One part has failed | The tank leaks or is undersized |
| Restroom fixtures | Valves or seals are worn | Fixtures are cracked or parts are scarce |
Signs it's time to call
- Several drains slow or backing up
- Low pressure that's getting worse
- Rusty water at the start of the day
- Sewer odor inside
Timing notes
We couldn't confirm which office issues plumbing permits for Princeton. Johnston County Inspections in Smithfield is the likely office, but check with Town Hall first. If you're planning a new connection or a bigger sewer load, ask where the plant expansion stands before you schedule the work.
When you call, you'll be connected with an independent local plumber who serves Princeton and nearby parts of Johnston and Wayne counties. Describe the building and its age, what the problem is doing and when the space can be closed. If the property is outside town on a well or an onsite wastewater system, say so up front.
