Can A Plumber or Irrigation Specialist Perform Backflow Testing?

If they hold a recognized backflow tester certification and are approved by your local water purveyor. In Los Angeles, that typically means credentials such as ASSE 5110, ABPA BPAT, or CA-NV AWWA Backflow Tester, plus current gauge calibration and agency registration. Without these, a test may be rejected—regardless of whether the person is a plumber or irrigation specialist.

For hassle-free compliance, Atlas Backflow Services provides certified, approved, and fully documented Backflow Testing Los Angeles for commercial, residential, industrial, and fireline assemblies.

Why job title isn’t enough

“Plumber” and “irrigation specialist” describe trade focus, not testing authority. A water purveyor (like LADWP or your city’s utility) typically requires:

• Recognized tester certification (e.g., ASSE 5110, ABPA BPAT, or CA‑NV AWWA)

• Active approval/registration with the purveyor

• Annual gauge calibration with a traceable certificate

• Proper submission of results via the utility’s forms or online portal

If you’re scheduling Backflow Testing Los Angeles, the safest route is to confirm credentials—not just trade experience. Atlas Backflow Services brings all required certifications and handles submissions so your results are accepted the first time.

What counts as a “qualified backflow tester” in Los Angeles?

Los Angeles–area utilities follow standardized procedures (often based on USC FCCC&HR) and maintain their own approved tester lists. While policies vary by purveyor, most accept these credentials:

• ASSE 5110 (Backflow Prevention Assembly Tester)

• ABPA BPAT (American Backflow Prevention Association)

• CA‑NV AWWA Backflow Tester

In addition, testers must keep their test gauges calibrated every 12 months (NIST-traceable documentation is commonly required), carry valid photo ID and certification cards, and submit test reports correctly through platforms like Tokay, XC2, SwiftComply, or the purveyor’s portal.

Atlas Backflow Services is approved with local water purveyors and follows all documentation and submission requirements for Backflow Testing Los Angeles.

Plumber vs. irrigation specialist: who should you hire?

Both can test legally—if certified and approved. The better choice depends on your system and what might be needed after testing.

• Domestic and commercial plumbing systems

  • A certified tester with a plumbing background can be helpful if your assembly fails and needs repair or replacement. In California, that typically involves a contractor license such as C‑36 (Plumbing) for repair work.

• Landscape/irrigation systems (PVBs, SVBs, DCVAs on irrigation lines)

  • A certified tester who regularly works with irrigation assemblies may diagnose outdoor vacuum breaker issues efficiently. Repairs may require a C‑27 (Landscaping) or appropriate contractor license.

• Fireline assemblies (Double Check Detector Assemblies, Reduced Pressure Detector Assemblies)

  • Many purveyors require a certified backflow tester; some sites also coordinate with NFPA 25 fire system requirements. Choose a provider experienced with fire protection assemblies and local reporting standards.

Testing and repair are two different scopes. Testing requires backflow tester certification and agency approval. Repairs require the appropriate California contractor license and insurance.

Atlas Backflow Services offers both compliant testing and properly licensed repairs for Backflow Testing Los Angeles, so you don’t have to hire multiple vendors.

What happens if you use a non-approved tester?

• Rejected results: Utilities can invalidate tests from non-approved providers.

• Compliance notices and fines: Missed deadlines or invalid submissions may trigger warnings, penalties, or even water shutoff.

• Repeat testing costs: You may pay twice—once for the invalid test and again for a compliant retest.

Avoid the hassle. Atlas Backflow Services schedules, tests, and submits correctly the first time, making Backflow Testing Los Angeles simple and predictable.

The minimum a tester must have (Los Angeles checklist)

Before you book, ask for proof of:

1. Backflow tester certification: ASSE 5110, ABPA BPAT, or CA‑NV AWWA

2. Water purveyor approval: Are they on your utility’s approved list?

3. Current gauge calibration: Certificate date, serial number, and lab details

4. Experience with your assembly type: RP, DCVA, PVB, SVB, fireline DCDA/RPDA

5. Submission process: Will they file results directly with your water agency?

6. Contractor license (if repairs may be needed): Often C‑36 for plumbing; ensure proper insurance

Atlas Backflow Services checks every box. Our Backflow Testing Los Angeles process includes reminders, compliant reporting, and clear documentation for your records and audits.

How often is testing required—and who sets the rules?

Most Los Angeles–area purveyors require annual testing for assemblies such as:

• RP (Reduced Pressure)

• DCVA (Double Check Valve Assembly)

• PVB/SVB (Pressure or Spill-Resistant Vacuum Breaker)

• Fireline backflow assemblies (DCDA/RPDA)

Certain high-hazard sites may have tighter schedules. Your water agency sets the due dates and format. We track these timelines and send reminders as part of our Backflow Testing Los Angeles service, so you stay ahead of deadlines.

Common myths, clarified:

• “Any licensed plumber can test backflows.”

  • Not necessarily. Without a recognized backflow tester certification and purveyor approval, the test can be rejected.

• “Irrigation specialists always handle outdoor backflows, so they can test them.”

  • Only if certified and approved. Field expertise is valuable, but compliance hinges on credentials and registration.

• “Calibration is optional if the tester is experienced.”

  • Incorrect. Most purveyors require a current, traceable calibration certificate. No calibration, no valid test.
