What Backflow Prevention Does
A backflow prevention assembly helps prevent water from flowing backward from a non-potable or higher-risk connection into the drinking-water system. Common applications include:
IrrigationCommercial connectionsOther cross-connection situations
Not every property requires the same assembly or testing schedule.
Testing, Repair, and Installation
Testing
Evaluates whether an existing assembly performs as required at the time of the test.
Repair
Addresses a failed or malfunctioning component.
Installation
Adds or replaces an assembly when the system requires one.
A test does not automatically include repair, replacement, or filing.
Credentials Matter
Backflow testing has certification requirementsBefore service, confirm that the person performing the requested work holds the credential required for that task. The North Dakota State Plumbing Board is a place to verify current license or tester status. Reporting
Before testing, ask:
• Who requested the test?
• What deadline applies?
• What form is required?
• Who receives the completed report?
• Is filing included in the service?
• Is retesting included after repair?
Do not assume the process is the same as a prior year.

After a Failed Test
Failed Test
A failed test can lead to cleaning, repair, replacement, or retesting. The correct next step depends on the actual failure and assembly condition. A failed result does not automatically mean the entire device must be replaced.
Match the Device to the Report
Confirm the documentation identifies the correct location, make, model, serial number, and test result — this helps prevent confusion on properties with multiple devices.
Commercial Backflow Needs
