We couldn't find a published water quality report for Princeton's town system, so the honest first step is a test of your own water before buying a softener or filter. Ask Town Hall for the latest report, and if you're on a well in rural 27569, test it too. Call the number on this page to be connected with a local plumber in Princeton.

What's known about Princeton's water
Princeton is a small eastern Johnston County town on US 70 between Selma and Goldsboro. The town runs its own water and sewer, and its wastewater plant discharges to the Little River. The plant treats about 275,000 gallons a day and is being expanded with USDA funding, and a state sewer moratorium has been lifted.
On drinking water, the record is thinner. No annual water quality report for Princeton turned up online, so we can't tell you the town's hardness, disinfectant level or sodium. Every public system is required to produce one each year, and Town Hall can give you a copy. That report, plus a simple tap test, is all you need to decide whether treatment is worth it.
Housing here is older. About 57% of Princeton homes were built before 1980, with a median year of 1977. In houses that age, discolored water or low flow is often the pipe, not the supply, so it's worth having a plumber look before buying equipment.
Outside town, the rural 27569 ZIP, with about 8,800 residents compared with the town's roughly 1,300, is a mix of Johnston County water and private wells.
How to choose without guessing
| If testing shows | Consider | Skip |
|---|---|---|
| Hardness above about 7 grains | A softener | Magnetic or "salt-free" claims without data |
| Disinfectant taste only | Carbon filtration | A softener |
| Iron or manganese on a well | Oxidizing filter | Undersized softener |
| Nothing unusual | Nothing, or a drinking-water filter | Whole-house equipment |
Signs that something needs attention
- Brown or rusty water after it sits overnight
- Scale on fixtures that keeps coming back
- A strong chemical taste or smell
- Stained laundry on a well
Timing notes
Read the town's report as soon as it's out each year. If you're on a well, test once a year and after floods or well repairs. If you're planning repiping in an older house, do that first; new pipe can change what you see at the tap. Then retest, and buy treatment only for what still shows up. That order keeps you from paying to filter a problem that new pipe already solved.
