A backflow test report is the official document that proves a backflow prevention device was tested, records the results, and satisfies regulatory requirements. But too many testers submit incomplete or inconsistent reports — leading to rejected submissions, compliance delays, and frustrated clients. This comprehensive guide covers exactly what every backflow test report must include, common mistakes that cause rejections, and how to produce professional-grade documentation every time.
Why Report Quality Matters
Your test report is more than paperwork — it's a legal document that:
- Proves compliance — Water utilities use your report to verify the property is in compliance with cross-connection control requirements
- Protects you legally — In the event of a contamination incident, your test report is evidence of proper testing procedures
- Reflects your professionalism — Sloppy reports lose clients. Clean, complete reports build trust and referrals.
- Determines payment — Many clients and property managers won't pay until they receive a professional report
Rejected reports waste time for everyone. According to water utility cross-connection control officers, 15-25% of submitted reports have errors that require follow-up — costing testers an average of 20 minutes per rejection to correct and resubmit.
Required Fields on Every Test Report
While specific form requirements vary by jurisdiction, the following fields are universally required across nearly all water utilities:
Device Information
| Field | Description | Common Errors |
|---|---|---|
| Serial Number | Manufacturer's serial number stamped on the device | Transcription errors — always double-check against the device |
| Manufacturer | Device manufacturer (Watts, Wilkins/Zurn, Febco, Ames, etc.) | Using brand vs. manufacturer name inconsistently |
| Model Number | Specific model designation | Confusing model with series number |
| Size | Nominal pipe size (3/4", 1", 1.5", 2", etc.) | Estimating instead of measuring |
| Device Type | RPZ, DCVA, PVB, SVB, DCDA, RPDA | Misidentifying device type |
| Location Description | Where the device is physically located | Vague descriptions like "in basement" |
Test Results
The specific test readings required depend on the device type:
RPZ Test Results Must Include:
- Check Valve 1 (CV1) PSID reading — Must be ≥5.0 PSID to pass
- Check Valve 2 (CV2) PSID reading — Must be ≥1.0 PSID to pass
- Relief Valve opening point — Must open at ≤2.0 PSID differential (typical)
- Pass/Fail determination for each component
DCVA Test Results Must Include:
- Check Valve 1 (CV1) PSID reading — Must be ≥1.0 PSID to pass
- Check Valve 2 (CV2) PSID reading — Must be ≥1.0 PSID to pass
- Pass/Fail determination for each check valve
PVB/SVB Test Results Must Include:
- Check valve PSID reading — Must be ≥1.0 PSID to pass
- Air inlet opening point — Must open at ≥1.0 PSI above atmospheric
- Did air inlet open? — Yes/No
Tester Information
- Tester name — Full legal name as it appears on certification
- Certification number — State or utility-issued certification ID
- Certification expiration date — Proves certification was valid at time of test
- Company name — Business entity performing the test
- Contact information — Phone number and/or email for follow-up questions
- Signature — Handwritten or digital signature attesting to the accuracy of results
Test Gauge Information
Many jurisdictions now require documentation of the test gauge used:
- Gauge serial number
- Gauge make/model
- Last calibration date
- Calibration expiration date
If your gauge calibration has expired, your test results may be rejected regardless of the readings. Learn about gauge calibration requirements →
Property and Service Information
- Property address — Full street address where the device is installed
- Water account number — If required by the utility (helps them match the report to the correct account)
- Property owner or contact name
- Service type — Domestic, fire, irrigation, etc.
Common Report Mistakes That Cause Rejections
Based on feedback from cross-connection control officers, these are the most frequent report errors:
| Mistake | Frequency | How to Avoid |
|---|---|---|
| Wrong or missing serial number | Very common | Photograph the serial tag and verify against your report before leaving the site |
| Missing tester signature | Common | Use digital signature capture to ensure it's never forgotten |
| Expired gauge calibration | Common | Track calibration dates and set 30-day reminders before expiration |
| Wrong device type recorded | Occasional | Know the visual differences between RPZ, DCVA, PVB, and SVB |
| Missing relief valve reading (RPZ) | Common | Use a checklist or digital form that requires all fields |
| Illegible handwriting | Very common (paper) | Switch to digital reporting — eliminates this entirely |
| Wrong form for the jurisdiction | Occasional | Verify which form your city accepts before arriving on-site |
| Test date doesn't match submission | Occasional | Submit reports within 24-48 hours of testing |
Digital vs. Paper Reports
The industry is rapidly moving from handwritten paper forms to digital test reports. The advantages of digital reporting include:
- Mandatory field validation — Digital forms won't let you submit with missing required fields
- Automatic calculations — Pass/fail determination based on entered readings
- Photo documentation — Attach site photos and serial tag images directly to the report
- Instant submission — Send reports to the city, client, and property owner simultaneously
- Searchable records — Find any past report instantly by serial number, address, or client
- Professional appearance — Clean, consistent formatting that reflects well on your business

Report Distribution: Who Gets a Copy?
Most jurisdictions require test reports to be distributed to multiple parties:
- Water utility / city — Required for compliance. Usually submitted via email, portal, or mail within a specified deadline (typically 10-30 days).
- Property owner — Should receive a copy for their records. Required by most jurisdictions.
- Device owner — If different from the property owner (e.g., tenant or HOA).
- Tester's records — You must retain copies for a minimum period (typically 3-5 years, varies by state). Check state record retention requirements →
Repair Documentation
When a device fails and is repaired, additional documentation is required:
- Original failed test results (before repair)
- Description of repairs performed
- Parts replaced (with part numbers)
- Name and certification of person performing the repair
- Post-repair passing test results
The repair and retest should be documented on the same report or cross-referenced with matching report numbers. See our guide to common repairs →

Frequently Asked Questions
What information must be included in a backflow test report?
Every backflow test report must include: device serial number, manufacturer, model, size, and type; test readings for each component (CV1, CV2, relief valve as applicable); pass/fail determination; test date and time; property address and water account number; tester name, certification number, and signature; and test gauge serial number with calibration date.
How long do I need to keep copies of backflow test reports?
Record retention requirements vary by state, but most require a minimum of 3-5 years. Some states (like California) require longer retention. As a best practice, keep records indefinitely in a digital system — storage is essentially free and old records can be valuable for tracking device history and defending against liability claims.
What happens if my backflow test report is rejected by the water utility?
You'll typically receive a notice identifying the specific error(s). You must correct the report and resubmit within the original compliance deadline. If the deadline has passed, you may need to coordinate with the utility to avoid penalties to your client. Common reasons for rejection include missing serial numbers, expired tester certification, and missing test gauge calibration dates.
Do I need to include photos in my backflow test report?
Photos are not universally required but are increasingly recommended and required by some jurisdictions. At minimum, photograph the device serial tag and the overall device condition. Photos protect you against disputes about device condition and prove you were on-site. Digital reporting platforms like FlowCert make photo attachment effortless.
