Backflow Testing & Prevention
Backflow Testing & Prevention in Chapel Hill, NC
Annual backflow testing keeps contaminated water from siphoning into your clean supply and satisfies OWASA compliance requirements for Chapel Hill properties.


Backflow preventers keep irrigation systems, boilers, and other cross-connections from allowing contaminated water to flow backward into the clean municipal supply during a pressure drop. OWASA requires annual testing for properties with backflow devices, and we're certified to perform that testing and file the results.
Beyond testing, we install backflow preventers for new irrigation systems or other connections that require one, sized and positioned to meet code.
When Backflow Testing Is Needed
- Annual testing due per OWASA requirements
- New irrigation system installation
- Visible leaking or dripping from the backflow device
- Property sale requiring compliance documentation
- Device age exceeding manufacturer service intervals


Our Backflow Testing Process
We test the device under controlled conditions to confirm both check valves and the relief valve are functioning within spec, using calibrated gauges as required for certified reporting.
If the device fails, we repair or replace it on the spot when possible, then retest and file the passing report so you stay in compliance without a second visit.

OWASA's cross-connection control program requires documented annual testing for properties with irrigation systems or other backflow risks, and we file test results directly so Chapel Hill property owners don't have to manage the paperwork themselves.


Why Backflow Prevention Matters
A sudden drop in municipal pressure, like from a nearby water main break, can reverse normal water flow; without a working backflow preventer, that reversal could pull irrigation chemicals or other contaminants into the drinking water supply.
Questions we get
