Backflow Testing in Princeton, NC

Princeton's situation

Princeton sits on US 70 in eastern Johnston County between Selma and Goldsboro. The Town bills water and sewer at Town Hall. The sources we found don't confirm who sells Princeton its water; Johnston County lists a Princeton Kenly water district for unincorporated areas nearby. Rural parts of the 27569 ZIP are a mix of Johnston County water and private wells.

Without a published program, we can't give you a test frequency or tell you where results go. The practical step is to call Town Hall before you add irrigation or a commercial connection and ask what device and paperwork it expects. If you're on Johnston County water outside town, ask the county instead.

About 57% of Princeton homes were built before 1980. Older supply lines can be undersized or corroded where a new assembly would go, so a plumber may recommend replacing a short section at the same time. The permit office for Princeton wasn't confirmed in our research; Johnston County Inspections is the likely office, so the plumber should verify before starting.

Test, repair or replace?

Signs it's time

• You're planning a lawn sprinkler system on Town water
• A business or church is adding a boiler, ice machine or fire line
• Your farm or rural lot has a well and a county water tap
• A device outside is dripping, cracked or frozen

Timing

Raise the backflow question while planning, not after the trench is dug. A sprinkler contractor and a plumber can agree on where the assembly goes before any pipe is laid, which keeps it close to the meter and easy to reach for testing later. For devices already in place, drain and insulate before cold weather, and inspect in spring before irrigation season. Keep any test or repair paperwork with your house records; if Princeton or the county ever asks, you'll have the history ready.
