Regulated backflow assembly and testing
Property owners are required to test regulated backflow assembly devices and report the results.
How it works
1. Apply for a plumbing permit
A plumbing permit is required when an RBA device is:
- Installed
- Replaced
- Relocated
- Removed
2. Register changes
The plumbing contractor must register the change using the online form. This happens when the work is complete.
3. Submit test results
We’ll notify the contractor when the registration is confirmed. Once confirmed, the contractor can submit the test results for the device.
Submit your test results
RBA devices must be tested when first installed and at least annually thereafter. Test results must be submitted online through The Compliance Engine (TCE).
To submit test results in TCE, the testing contractor must:
- Be a MN-state certified backflow tester
- Create a TCE account
- Register the RBA device change and receive confirmation
Device testing fees
Fees are per device.
- $18 per test
- $500 non-compliance penalty
- $5 late fee (less than 30 days)
- $10 late fee (more than 30 days)
Additional fees may be added for non-compliance.
