Backflow Testing in Four Oaks, NC

Four Oaks water and backflow

The Town of Four Oaks provides water, sewer and garbage in its service area. It doesn't treat water itself; it buys Neuse River water from Johnston County West, disinfected with chloramine. The 27524 ZIP is far larger than the town, though, and outlying homes may be on Johnston County water or private wells.

Research for this site didn't find a Four Oaks program page, interval or tester list. That's a gap in what's published, not proof nothing applies. If you're a Town water customer adding irrigation, or a business near I-95 Exit 87 adding equipment tied to the supply, ask the Town what device it wants before work begins. Johnston County water customers follow the county's rules.

Four Oaks is one of the few small Johnston towns that runs its own building inspections, so a plumbing permit for a new assembly would go through the Town's Planning, Zoning and Inspections office instead of the county. Housing here is mixed in age, with a median build year of 1985.

Common device types

Signs to call

• You're installing an in-ground sprinkler system
• A commercial kitchen, car wash or similar business is opening
• Your property has both a well and public water
• An existing assembly is leaking or was damaged
• The Town or county has contacted you about a device

Timing

Put the backflow question at the start of any irrigation or commercial project, since the device has to be in place before the system runs. Sprinkler installers sometimes leave the backflow piece for last, and then the zone layout has to be reworked to fit an assembly near the meter. Settling the device type first avoids that. If you already have an outdoor assembly, drain and cover it before freezing nights. In spring, check for cracks before turning sprinklers back on, and open the supply valve slowly so a damaged part shows itself as a drip rather than a burst.
