Backflow repair and recertification

Backflow Repair & Maintenance

Repair, replacement and retesting for backflow assemblies that fail, leak or need service before recertification.

Quick answer

Can a failed backflow device be repaired and recertified?

Often, yes. AO Backflow & Fire diagnoses failed backflow assemblies, recommends the appropriate repair or replacement, then retests and documents the device for recertification.

Common questions

What should I send after a failed test?

The failed test report, a photo of the device tag or assembly, leak details and access notes help AO prepare for the repair visit.

Is replacement sometimes better than repair?

Yes. If the assembly is too worn, damaged or not cost-effective to repair, AO can recommend replacement and plan retesting after installation.

Repair and recertification

A failed backflow device must be repaired, retested and documented before recertification.

AO diagnoses the assembly, repairs serviceable components or recommends replacement, then retests and documents the completed work.

Diagnosis and repair process

  1. Identify failed check, relief valve, seal or shutoff issue
  2. Repair serviceable components or recommend replacement when needed
  3. Retest and document the assembly after work is complete

Repair work may include

  • Valve, seal and component replacement
  • Leak repair and troubleshooting
  • Device replacement planning when repair is not cost-effective
  • Post-repair testing and recertification
