New Orleans
Why New Orleans properties test yearly
In New Orleans, backflow assemblies cluster where the cross-connections are: irrigation, pools, hose bibs. Double shotgun rentals with absentee post-storm landlords and shared-wall water migration. French Quarter and Garden District: 1700s–1800s structures with layered centuries-old systems — especially vulnerable. Local water purveyors take testing seriously, and so should you.
Around Orleans Parish County, the testing cycle is routine: double shotgun rentals with absentee post-storm landlords and shared-wall water migration.. Shifting soil: shifting gumbo clay over a high water table moves with moisture cycles, stressing buried supply lines and slab foundations — a leading cause of slab leaks. The pro's job is keeping your assembly — and your paperwork — current.

When testing is due
Annual test notices, new irrigation, and visible damage are the usual prompts. Know them.
- 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.
Test, repair, install — what's covered
Backflow work is equal parts plumbing and paperwork — the test has to satisfy the water authority, not just the homeowner. Here is the full scope.
- 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.
What to do about that test notice
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.
How backflow testing works
The process is standardized for a reason. The steps in order.
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.
Test, repair, or replace?
Assembly type, condition, and accessibility set the price. Here is what the tester evaluates.
- 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.
