Backflow Testing in Coats, NC

Does Coats have its own backflow rules?

We couldn't find any published. Coats Public Works runs a small system, roughly 29 miles of lines and two elevated tanks, fed through metered connections to Harnett Regional Water's Cape Fear River supply. The Town's water service page doesn't describe a cross-connection program, interval or tester list. That's missing information rather than a clean bill. Before adding sprinklers or a business connection, ask Coats Public Works what device it wants. If you're outside town in 27521, you might be a Harnett Regional Water customer or on a private well instead.

What does a Coats homeowner actually need?

For a house with no irrigation and no special equipment, often nothing beyond basic hose protection. A hose bibb vacuum breaker on each outdoor faucet stops a hose in a bucket, pool or sprayer from siphoning back. Add an in-ground sprinkler system and you need an approved backflow assembly; plumbing codes generally require one on irrigation. Farm uses, such as filling chemical tanks or watering livestock from a hose, call for stronger protection. And if your property kept a well after connecting to town water, the well has to be fully separated.

How does the work get permitted and done?

Coats doesn't run its own building inspections. Harnett County Inspections handles plumbing permits and inspections for the town, and the county won't issue a building permit until the Town grants a zoning permit. A plumber installing a new assembly will usually handle that sequence, but allow a little extra time for the two approvals. About 55% of Coats homes were built before 1980, with a median of 1978, so the pipe near the meter may be worth replacing while the device goes in. Once a testable assembly is installed, it's tested with a gauge to confirm it works. Keep that first report; it's the baseline if the Town or the county ever asks for records later.

Local note

The Town's 2025 water report found no detectable lead or copper at the 90th percentile and no homes above action levels. Backflow protection is part of keeping the system that way.
