Fargo
The Fargo angle on backflow
A Fargo tester sees the same assemblies year after year and knows their failure modes. Downtown and near-NDSU early-1900s homes feature original-era plumbing and aging foundations. Freeze damage and worn check valves write most of the failure reports.
From Downtown Fargo to North Dakota State University area, Fargo irrigation systems all share one requirement: a tested backflow assembly between the sprinklers and the drinking water. Downtown and near-NDSU early-1900s homes feature original-era plumbing and aging foundations. Annual testing is simply the cost of that protection.

Signs you need backflow service
You will rarely 'feel' a backflow problem. Here is what to watch for instead.
- A city notice that your backflow test is due or overdue.
- An irrigation system with no visible backflow device.
- Water discoloration after a pressure drop or nearby main break.
- A backflow preventer leaking or dripping from its relief ports.
- A new irrigation system, boiler, or commercial fixture being installed.
What backflow service includes
From gauge calibration to the submitted report, this is what the service covers.
- Testing of the existing backflow assembly with calibrated gauges.
- Test reporting in the format your water purveyor requires.
- Repair or rebuild of assemblies that fail the test.
- New installations for irrigation, pools, and other cross-connections.
- Correct assembly selection for the hazard level and local code.
- Scheduling reminders guidance so the next annual test does not slip.
Before the test
The notice has a deadline, and missing it has consequences. Handle it in this order.
Safe to do now
- Know whether your property has a backflow device and where it is.
- Keep the area around the device clear and protect it from freezing.
- Track your test due date — cities fine for missed tests.
- Do not remove or bypass the device, even temporarily.
Stop — call a pro
- Testing requires certified gauges and training — it is not a DIY task.
- Do not disassemble a backflow preventer yourself — springs are under tension.
- Ignoring a failed test notice — the water authority can shut off service.
- Installing an irrigation tie-in without backflow protection where code requires it.
The process, step by step
Testing follows a strict protocol — it has to, since the water supply is at stake. Here is the sequence.
Device check: the pro identifies your backflow assembly type and its test cocks.
Certified test: using gauges, the tester verifies each check valve and relief valve holds per spec.
Report and file: results go to you and, where required, to the water authority.
Repair or replace: failed assemblies get rebuilt with new internal kits or replaced.
The decision factors
The test result drives everything after it. Understand the forks in the road.
- Annual test versus repair versus new installation.
- Assembly type and size — residential irrigation devices versus larger commercial units.
- Whether a failed device needs a rebuild kit or full replacement.
- Filing and reporting fees charged by some water authorities.
- Accessibility — devices in pits or enclosures take longer to service.
