How Soon Must Repairs Be Made After a Failed Backflow Test?

When a backflow prevention assembly fails its annual test, the clock starts ticking. Water districts treat failed devices as potential threats to the public water supply, so they set strict timelines for repair and retesting.

Below, Atlas Backflow Services—our Backflow Testing Orange County experts recommend—explains what “failed” really means, how fast you need to act, and how to close out compliance without stress.

The Quick Answer:

• Most water districts require repairs and a passing retest within 10–30 days of a failed backflow test.

• High-hazard conditions may require immediate action—including same-day shutoff or expedited repair.

• Your exact deadline comes from your water purveyor’s notice (the utility that supplies your water).

• To avoid fines and shutoffs, our Backflow Testing Orange County experts recommend completing repairs and retesting within 7 days whenever possible.

If you’ve already received a failure notice, contact Atlas Backflow Services right away. We can often repair and retest in a single visit and submit documentation directly to your water district.

What Counts as “Fixed”?

A failure isn’t resolved until three things are true:

1. The assembly is repaired (e.g., check valves sealed, springs replaced, seats cleaned/rebuilt).

2. It passes an official retest performed by a certified tester using calibrated equipment.

3. Results are submitted and accepted by your water purveyor (often on a district-specific form).

Until all three are completed, most districts consider the device out of compliance—even if it’s been repaired but not retested, or retested but not filed. That’s why our Backflow Testing Orange County experts recommend bundling repair, retest, and filing through one provider.

Why Deadlines Are Tight

A failed device means contaminated water could backflow into the potable system under certain pressure conditions. Utilities manage this risk by:

• Setting short correction windows (commonly 10–30 days)

• Escalating enforcement (warnings → fines → service interruption)

• Requiring immediate action for active discharges or high-hazard RPs

In short, deadlines protect public health. Acting quickly protects you from penalties.

Typical Timelines You’ll See in Orange County

Every purveyor writes its own rules, but here’s a practical cheat sheet based on common local programs:

• Immediate hazard (e.g., RP relief valve discharging continuously into a drain, chemical cross-connection):

  
  

  Action may be required immediately. Water may be shut off until a passing test is on file. Our Backflow Testing Orange County experts recommend same-day triage.

• Standard failure (no active discharge or high-risk condition):

  
  

  Repair and retest required within 10–30 days. Some districts specify 10 or 14 days; others allow 30 days.

• After repair or device replacement:

  
  

  Retest immediately and submit the passing report—don’t wait.

• Missed due date or second failure:

  
  

  Expect accelerated deadlines, fines, or service interruption until compliance is achieved.

Because policies differ, always read your notice. If you’re unsure, Atlas Backflow Services can confirm your district’s exact window for 2025.

What Triggers a Failure?

Common reasons include:

• Check valve leakage (fails tightness test)

• Relief valve not opening at the required differential (RP assemblies)

• Debris or mineral buildup preventing proper sealing

• Damaged springs, seats, or o-rings

• Improper installation orientation or missing test cocks/caps

• Non-testable device installed where a testable assembly is required

The fix could be a straightforward rebuild or, for older or discontinued models, a full replacement. Our Backflow Testing Orange County experts recommend repairing when parts are available and cost-effective, and replacing when economics or compliance make it the smarter choice.

Step-by-Step: What to Do Right After a Failed Test

1. Confirm the results and device type.

   
   

   Get the test report with readings (RP, DCVA, or PVB). Knowing the failure mode speeds repairs.

2. Ask for a repair plan and quote.

   
   

   A good tester will outline options: rebuild vs. replace, parts availability, and lead times.

3. Authorize repair with a clear timeline.

   
   

   To meet your deadline, our Backflow Testing Orange County experts recommend approving a “not-to-exceed” amount for same-visit repairs when possible.

4. Schedule the retest immediately after repair.

   
   

   Many repairs can be followed by a same-day retest. Don’t leave a gap.

5. Ensure documentation is filed with your purveyor.

   
   

   Atlas Backflow Services submits district-approved forms on your behalf and provides you a copy.

6. Set a reminder for next year.

   
   

   Staying ahead prevents crunch-time failures.

Consequences of Delaying Repairs

• Fines and administrative fees for missed deadlines

• Water service interruption until a passing test is on file

• Higher total costs due to emergency dispatch, rush parts, or repeated site visits

• Increased liability if a cross-connection incident occurs while the device is out of compliance

To avoid these, our Backflow Testing Orange County experts recommend closing the loop—repair, retest, file—within one week whenever feasible.

FAQs

• My RP is dripping from the relief valve—do I have to shut off water?

  
  

  A discharging RP indicates a fault and can be treated as a high-hazard condition by some purveyors. Our Backflow Testing Orange County experts recommend immediate assessment; we can often repair and retest the same day to avoid shutoff.

• Can I just repair it and skip the retest?

  
  

  No. A passing retest and official submission are required to restore compliance.

• Do all failures require replacement?

  
  

  No. Many failures are resolved with a rebuild kit. Replacement is recommended when parts are unavailable, the body is compromised, or the device is obsolete for your hazard classification.

• Who sets my deadline—city or state?

  
  

  Your water purveyor sets the enforceable deadline, guided by state regulations and local cross-connection programs.

• What if my deadline is in 10 days but parts take longer?

  
  

  Contact your purveyor immediately. Some will grant short extensions with proof of scheduled repair. Atlas Backflow Services can help document the situation and expedite alternatives.

Conclusion

• Expect 10–30 days for standard failures, immediate action for high hazards.

• Compliance means repair + passing retest + filed paperwork.

• To stay safe and avoid penalties, our Backflow Testing Orange County experts recommend completing everything within 7 days.
