Backflow Testing in Pittsboro, NC

If you own a property in Pittsboro with an irrigation system, a fire line, a well-and-city connection, or a commercial water service, there is almost certainly a backflow prevention assembly somewhere on it — and it has to be tested by a certified tester to prove it still works. That single annual test is the whole point of this page. We send a certified technician, run the device through its paces on a calibrated gauge, and turn the result into a report that satisfies TriRiver Water.

Pittsboro is a town of sharp contrasts, and the plumbing reflects it. Around downtown and out on the rural roads you’ll find older homes and aging assemblies that were installed decades ago and may need a rebuild before they pass. Then there’s Chatham Park — thousands of acres of new construction since 2018 running modern, high-efficiency systems with assemblies that are newer but still legally due for their annual check. We test both ends of that spectrum every week.

RPZ and double-check assemblies, tested right

The two devices we see most around Pittsboro are reduced-pressure zone (RPZ) assemblies and double-check valve assemblies. An RPZ protects against the highest-hazard connections; a double-check covers lower-hazard ones. Both have moving check valves and relief components that wear, stick, or foul over time, which is exactly why an annual test exists. If yours fails, we’ll show you the reading, explain what failed, and quote the repair or replacement before any work begins — no surprises.

Pittsboro’s water and its cross-connection control program are run by TriRiver Water, the regional authority Pittsboro joined in 2024. Here is what that means for testing your assembly:

• Test at least once a year. Backflow assemblies are tested annually under North Carolina’s drinking-water rules, which TriRiver enforces locally.
• Residential irrigation may qualify for every three years. Under NC Senate Bill 166, an irrigation system with no chemical feed or booster pump can be tested once every three years instead of annually, with a yearly certification that no chemical feed is present.
• A certified tester must do the work. Testing must be performed by a TriRiver-approved tester using a kit calibrated within the past year and documented on the North Carolina Backflow Prevention Tester Test and Maintenance Report.

TriRiver recently updated how test reports are submitted, so we confirm the current process directly with them and file your report for you — you never have to track the paperwork or chase the change.
