Overview
This Backflow Preventer Annual Test template captures the information needed to document a compliant annual test: inspection details, device identification, pressure readings, certification, and any deficiencies or corrective actions. It is built for certified testers who need a clean record of what was tested, where the device is installed, what the readings were, and whether the assembly passed or failed.
Use it for routine annual compliance testing, post-repair retesting, or any inspection required by a local water authority or AHJ. The structure follows the way a tester works in the field: confirm the site and purpose, identify the device, record the test-port and pressure readings, then complete the certification and follow-up sections. That makes it easier to avoid missing a serial number, skipping a reading, or forgetting to note that a failure was reported.
Do not use this as a generic plumbing maintenance checklist. It is specifically for backflow preventer testing and compliance documentation, not for unrelated water system inspections. If the device is out of service, inaccessible, or outside the tester’s authority, record the limitation and route the issue to the responsible owner or authority before closing the report.
Standards & compliance context
- This template supports documentation practices commonly expected under local backflow prevention programs and AHJ requirements for potable water protection.
- The certification and result fields help align the record with plumbing and water safety expectations used by municipal authorities and utility programs.
- If the site follows a formal quality system, the report number and corrective action fields support traceability consistent with ISO 9001-style record control.
- For facilities with broader safety or water hygiene programs, the template can be paired with internal maintenance procedures and local code requirements without changing the test logic.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template

- Device type
- Manufacturer
- Model number
- Serial number
-
Size
Record nominal pipe size, such as 1 in, 2 in, or 4 in.
-
Installation location
Identify the exact physical location of the device, including building, room, vault, or riser.
Test Readings and Functional Results
This section captures the measured values that determine whether the backflow preventer is functioning within acceptable limits.
- Initial condition of device and test ports
- Upstream pressure
- Downstream pressure
- Relief valve opening pressure
- Check valve 1 differential pressure
- Check valve 2 differential pressure
Certification and Compliance
This section records the final compliance outcome and provides the formal statement needed for audit and AHJ review.
- Test result
-
Certification statement completed
Confirm the tester has signed or otherwise certified the results as accurate.
- AHJ or customer notified of failure
- Inspection report number
Deficiencies and Corrective Actions
This section turns failed findings into a tracked follow-up item so repairs and retests do not get lost after the inspection.
- Deficiencies observed
- Corrective action required
-
Corrective action details
Describe repairs, replacement, retest requirements, or follow-up actions needed.
- Retest required
How to use this template
- Start by entering the inspection date, facility location, tester identity, certification number, expiration date, purpose, and the governing standard or local authority requirement.
- Identify the backflow device by type, manufacturer, model, serial number, size, and installation location so the report matches the asset on site.
- Perform the test in the order shown and record the initial condition, upstream pressure, downstream pressure, relief valve opening pressure, and each check valve differential pressure.
- Mark the test result and complete the certification statement only after the readings are verified and the device status is clear.
- If the device fails or shows a deficiency, document the corrective action required, note who was notified, and indicate whether a retest is required.
- Save the report number and attach any photos, repair notes, or retest records so the compliance trail stays connected.
Best practices
- Record the exact device location as installed, not just the building name, so the tester can find the same assembly on the next annual cycle.
- Capture the certification number and expiration date before the test begins to avoid invalid reports from expired credentials.
- Document the initial condition of the test ports and assembly before connecting gauges, because damaged or inaccessible ports are a reportable deficiency.
- Enter each pressure reading immediately during the test instead of reconstructing values from memory after leaving the site.
- Treat a failed differential pressure result as a compliance event, not just a maintenance note, and assign a clear corrective action and retest path.
- Notify the AHJ or customer promptly when the device fails or cannot be tested, and document that notification in the report.
- Use the same device naming convention across annual cycles so trend review and asset tracking stay consistent.

Common use cases
Frequently asked questions
Which backflow devices does this annual test template apply to?
Use it for annual testing of backflow preventers where the device type, test ports, and differential pressure readings must be documented. It works well for reduced pressure zone assemblies, double check assemblies, and similar devices that require certified testing. If your local water authority or AHJ requires a different form, customize the device fields and result language to match that requirement.
How often should this inspection be completed?
This template is designed for annual testing, which is the most common cadence for backflow preventer compliance programs. Some jurisdictions, facilities, or device types may require more frequent testing after repairs, relocation, contamination events, or failed results. Use the inspection purpose field to note whether the test is routine annual compliance, post-repair verification, or a special AHJ-required test.
Who should fill out this template?
A certified backflow tester or other qualified inspector should complete the test readings and certification fields. Facility staff can use it to track scheduling, device locations, and corrective actions, but the actual test result should come from the certified tester. If your program separates testing from maintenance, assign the corrective action section to the responsible maintenance owner after the inspection.
What regulatory or code references should be used with this form?
Reference the applicable local water authority requirements, plumbing code, or AHJ program rules in the inspection details section. Many programs align with backflow prevention standards used by municipalities, utilities, and plumbing authorities, so the form should capture the exact standard or local requirement that governs the test. If the site has multiple jurisdictions, note the governing authority for each device location.
What are the most common mistakes when using a backflow test form?
Common mistakes include missing device serial numbers, incomplete pressure readings, and failing to record whether the initial condition of the test ports was acceptable. Another frequent issue is documenting a failed test without assigning a corrective action or retest requirement. This template helps prevent those gaps by separating identification, test results, compliance status, and follow-up actions.
Can this template be customized for different device types or site layouts?
Yes. You can add fields for additional check valves, bypass assemblies, freeze protection, or irrigation zones if your site uses them. You can also rename the installation location field to match your asset map, add building or riser identifiers, and include photos or barcode/QR asset IDs for faster retrieval.
How does this compare with an ad-hoc inspection note or spreadsheet?
An ad-hoc note often misses the readings and certification details needed to prove compliance after the fact. This template organizes the inspection in the same order a tester performs it, which makes it easier to complete accurately and easier for an AHJ or customer to review. It also creates a consistent record for trend tracking, retests, and corrective action follow-up.
What should happen if the device fails the test?
Record the failed result, describe the deficiency, and note whether the AHJ or customer was notified. Then assign the corrective action, document the repair or replacement details, and mark whether a retest is required. If your process allows, link the failed report number to the retest record so the compliance trail stays intact.
