Why Annual Testing Is Genuinely Required, Not Just Recommended
Backflow preventers contain internal check valves and seal components that can genuinely degrade or fail gradually over time without producing any visible external sign of that degradation — the device can appear entirely normal from the outside while its internal protective function has actually been compromised. Annual testing exists specifically to confirm the device still genuinely functions correctly before it's actually needed during a real emergency, rather than only discovering a failure after backflow has already occurred and caused actual contamination.
What the Actual Testing Process Involves
A certified backflow tester connects specialized gauges directly to the device and systematically checks that each internal check valve component holds pressure correctly under standardized test conditions specifically designed to verify proper function — this is a genuinely technical process requiring specific certification and equipment, not something a typical property owner would reasonably perform themselves.
Typical Test Duration
Most standard residential or light commercial backflow device tests are completed within 30 to 60 minutes, making this a genuinely contained, relatively quick annual visit rather than an extended, disruptive undertaking for most property owners.
Reporting Requirements: A Step Many Property Owners Don't Realize Is Necessary
Test results generally need to be formally submitted to the local water authority in order for the property to remain in proper compliance — this specific reporting step is one that many property owners genuinely aren't fully aware of until their existing device happens to become overdue, at which point they may face compliance issues they weren't necessarily anticipating.
Why This Reporting Step Genuinely Matters
Without proper reporting, the water authority has no formal, official record confirming your device has actually been tested and confirmed functional, even if the test itself was genuinely performed correctly — meaning the reporting step is just as essential to actual compliance as the technical testing itself, not merely an optional administrative afterthought.
Who Is Actually Qualified to Perform This Testing?
A certified backflow tester specifically — this particular certification, distinct from general plumbing licensure, is specifically required to legally perform this type of testing. Many licensed plumbing companies, including ours, maintain this specific certification in-house, allowing us to handle both the testing itself and the required reporting as a single, coordinated, streamlined service for property owners.
What Happens If Testing Is Skipped or Simply Forgotten?
Non-compliance with this requirement can genuinely result in water service being restricted specifically for the irrigation connection (or whatever specific connection the device protects) until proper testing is actually completed and the results formally reported — a genuinely disruptive consequence worth avoiding through simply staying current on this straightforward annual requirement rather than facing it after the fact.
Building Annual Testing Into Your Property Maintenance Routine
Since this is genuinely a required annual task rather than optional or occasional maintenance, building it into your regular yearly property maintenance schedule — perhaps timed alongside spring irrigation system startup, as covered in more detail in our seasonal maintenance content — helps ensure it doesn't get overlooked or forgotten amid other property management responsibilities.

Frequently Asked Questions
What happens if I skip annual testing?
Non-compliance can result in water service being restricted for the irrigation connection until testing is completed and properly reported to the water authority.
Who is qualified to perform backflow testing?
A certified backflow tester — many licensed plumbing companies, including ours, maintain this specific certification in-house rather than needing to subcontract it separately.
Is annual testing genuinely required by law, or just generally recommended as good practice?
For qualifying connections like irrigation systems, it's genuinely a legal requirement in Arlington, not merely an optional best practice.
How do I know if my specific property has a backflow device requiring this annual testing?
If you have an irrigation system, fire sprinkler system, or certain commercial connections, you very likely have a device requiring this — a plumber can confirm your specific property's exact situation.
Can I perform backflow testing myself to save on the cost of professional service?
No — this genuinely requires specific certification and specialized equipment that isn't something a typical property owner would have access to or be legally authorized to use for this purpose.
Does the water authority actually track and enforce this testing requirement?
Yes — this is part of why proper reporting after testing matters so much, since the water authority maintains compliance records and can restrict service for connections that fall out of compliance.
