BACKFLOW PREVENTION ASSEMBLY
A SMALL DEVICE WITH AN IMPORTANT JOB
Water normally travels in one direction from the public water system to your property. A sudden pressure drop or pressure change can reverse that flow. Without effective backflow protection, water from an irrigation system may be drawn back toward the potable water supply. Backflow prevention assemblies are mechanical devices with internal valves, springs and seals. Freezing, debris, wear, corrosion or improper repairs can prevent them from working as designed. Testing confirms whether the assembly is operating correctly and identifies repairs that may be needed before a failure creates a larger problem.
WHY IRRIGATION SYSTEMS ARE REGULATED:
Irrigation piping is exposed to soil, standing water, lawn treatments and other potential contaminants. A backflow preventer creates a protective barrier between that system and the drinking-water connection.
KNOW YOUR TESTING SCHEDULE
RESIDENTIAL & COMMERCIAL REQUIREMENTS ARE NOT THE SAME
North Carolina law sets an important limit for certain residential systems: a locally owned public water system may not require periodic testing more often than once every three years for a residential irrigation backflow preventer when the irrigation system does not apply or dispose chemical feeds. That three-year limitation does not create one universal schedule for every backflow assembly. Commercial systems, high-hazard connections, irrigation systems with chemical injection, new installations, repaired or relocated assemblies and other regulated connections may be subject to annual testing or additional requirements. Your serving water utility determines the due date and reporting process that apply to your account.
| PROPERTY / SYSTEM | TYPICAL SCHEDULE | IMPORTANT QUALIFICATION |
|---|---|---|
| Residential Irrigation | Generally every 3 years | Applies to locally owned public water systems when the residential irrigation system has no chemical feed. Follow the utility's assigned due date. |
| Commercial Irrigation | Often annually | The residential three-year limitation does not apply. Local utility rules and hazard classification control. |
| Chemical-feed or high-hazard system | May be annual or more restrictive | Additional protection, a different assembly type or prompt corrective action may be required. |
| New, repaired or relocated assembly | Test when work is completed | The water provider may require a passing report before approving or continuing service. |

FREQUENTLY ASKED QUESTIONS
QUESTIONS ABOUT BACKFLOW TESTING?
Backflow testing requirements can vary depending on your water provider, property, and irrigation system, so it’s important to stay ahead of any required testing or documentation. You may need to schedule irrigation backflow testing when you receive a testing notice or upcoming due-date reminder, after a new backflow prevention assembly is installed, or following repairs, replacement, or relocation of an existing assembly. Testing may also be required when an irrigation system is reactivated, when purchasing or taking over management of a property with an unknown testing history, or before a compliance deadline that could affect your water service or account status.
We’ve answered some of the most common questions about irrigation backflow testing, including when testing is required, how the process works, and what to expect before and after your appointment.
