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 the pro does on a backflow call
A proper visit ends with a passing test and filed paperwork. Expect these steps.
- 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.
Safe first steps
Locate your assembly, check the paperwork, and book the test. Details below.
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
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?
A passing test is cheap; a failed assembly is a project. These factors determine which one you are buying.
- 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.
