AF Form 844: Backflow Prevention Inspection Data (2026 Guide)

AF Form 844: Backflow Prevention Inspection Data (2026 Guide) – Backflow prevention is a critical component of protecting potable water systems from contamination on U.S. military installations. The AF Form 844, titled Backflow Prevention Inspection Data, is a specialized U.S. Air Force form used to document inspections of certain backflow prevention devices, particularly vacuum breakers and related assemblies.

This article provides an overview of AF Form 844, its purpose, how it fits into the broader Air Force backflow prevention program, related forms, and practical guidance for civil engineering personnel, backflow prevention program managers (BPMs), and certified testers. Information is drawn from official Department of the Air Force publications and e-Publishing resources.

What Is AF Form 844?

AF Form 844 is an official Air Force form used to record inspection data for backflow prevention devices, specifically often associated with vacuum breaker inspections. It helps ensure compliance with cross-connection control requirements to safeguard drinking water supplies.

  • Full Title: Backflow Prevention Inspection Data (sometimes referenced in context with vacuum breakers).
  • Historical Note: Older references list an issue date around April 1981, though forms are managed through current Department of the Air Force (DAF) processes.
  • Purpose: To systematically document device location, inspection dates, test results, deficiencies, corrective actions, and inspector certification details.

Note on Related Forms: Many sources distinguish AF Form 843 as the primary form for general or spring-loaded backflow prevention device inspection data, while AF Form 844 is referenced for vacuum breaker-specific or complementary inspection records. Always verify the exact form needed for your device type against current guidance. AF Form 845 is used for Cross Connection Information.

Why Backflow Prevention Matters in the Air Force?

Backflow occurs when water flows in the reverse direction, potentially introducing contaminants into the potable water supply through cross-connections. The Air Force maintains a robust program to prevent this, protecting personnel health and ensuring regulatory compliance with the Safe Drinking Water Act and other federal, state, and local requirements.

Key governing documents include:

  • DAFMAN 32-1067, Water and Fuel Systems (current as of July 2025) — This manual details responsibilities for water systems, including the appointment of a Backflow Prevention Program Manager and requirements for inspections, testing, and certification.
  • Legacy AFI 32-1067 and related instructions that consolidated water systems, backflow prevention, and environmental compliance guidance.

Bases under U.S. jurisdiction primarily follow the Uniform Plumbing Code (UPC) Section 603 on Cross-Connection Control, supplemented by Air Force-specific requirements. Fire protection systems have separate guidance (e.g., referencing AWWA Manual M14 for backflow on fire suppression systems).

Who Uses AF Form 844 and Related Documentation?

  • Backflow Prevention Program Manager (BPM): Appointed by the Base Civil Engineer (BCE) or equivalent; must have training in plumbing and backflow systems.
  • Certified Testers: Only qualified military, civilian, or contracted personnel certified to test, maintain, install, and repair backflow devices. Certification aligns with state/local standards or approved Air Force programs.
  • Civil Engineering Personnel (3E4X1 Water and Fuel Systems Maintenance): Responsible for installation, inspection, maintenance, and documentation.
  • Facility Managers and Contractors: For periodic reporting and compliance.

Inspections must ensure devices are accessible (typically 1–5 feet above floor/grade with proper clearances) and installed per manufacturer instructions and code.

How to Use AF Form 844 in the Backflow Prevention Program?

  1. Identify and Inventory Devices: Maintain an inventory of backflow prevention assemblies and cross-connections. Document locations using sketches or digital tools (older references mention AF IMT 845 for mapping).
  2. Perform Inspections and Tests: Conduct tests at required frequencies (often annually or per code/manufacturer). Record:
    • Device type and location
    • Inspection/test date
    • Test results (e.g., pressure differentials, leaks, functionality)
    • Any deficiencies or repairs needed
    • Inspector’s name, certification, and signature
  3. Document on the Form: Use AF Form 844 (or 843 as appropriate) to capture inspection data clearly and legibly.
  4. Report and Retain Records: Submit data periodically to the government representative or BPM. Retain records per Air Force Records Disposition Schedule and DAFMAN 32-1067 guidance.
  5. Corrective Actions: Address failures promptly and re-test as required.

The program emphasizes eliminating cross-connections where possible before relying on devices. Personnel must follow tiered compliance (T-0, T-1, etc.) and waiver processes outlined in DAF publications.

  • Certification: Testers must hold current certification. Overseas or specific locations may have additional host-nation considerations.
  • Fire Protection Exemption: Fire suppression systems follow different rules but still require appropriate backflow protection.
  • Environmental Integration: Ties into broader water quality, wastewater, and pollution prevention efforts (see AFI 32-7001 for release reporting).
  • Training: Water and Fuel Systems Maintenance career field (AFSC 3E4X1) includes backflow prevention in its core tasks.

Regular flushing of distribution systems, hydrant flow tests, and valve exercising complement the backflow program.

Download and Access AF Form 844

The official download is available through the Air Force e-Publishing portal:

Always use the most current version. Previous editions may be obsolete. Authorized users can access PDFs directly from the static repository.

For the full backflow prevention program details, review DAFMAN 32-1067 (available on e-publishing.af.mil).

Best Practices for Compliance (U.S. Air Force Context)

  • Appoint and train a dedicated BPM.
  • Integrate backflow documentation into asset management systems (e.g., NexGen/Tririga or successors).
  • Coordinate with Public Works, Environmental, and Medical teams.
  • Stay current with state/local regulations, as they may impose stricter requirements.
  • Conduct cross-connection control surveys every five years or as directed.

Proper use of forms like AF Form 844 helps demonstrate due diligence during audits, Environmental Compliance Assessment and Management Program (ECAMP) reviews, and inspections.

Conclusion

AF Form 844 plays a supporting role in the Air Force’s commitment to safe, reliable potable water systems by standardizing the documentation of backflow prevention device inspections. Whether you are a civil engineer, certified tester, or program manager on a U.S. installation, accurate record-keeping protects public health and ensures mission readiness.

For the latest form and guidance, visit the official Department of the Air Force e-Publishing site and consult DAFMAN 32-1067. If you need assistance with backflow certification training or program implementation, contact your local Base Civil Engineer or the appropriate MAJCOM functional office.
