Backflow Testing in Minnesota: Costs, Requirements & How to Find the Best Certified Testers
Minnesota has the most structured tester credential system in the U.S. — the DLI issues two separate certifications: Backflow Prevention Tester (BT, ASSE 5110) for testing only, and Backflow Prevention Rebuilder (BF, ASSE 5110 + 5130 + plumbing license) for testing AND repairs. Only a BF holder can legally repair a failed assembly in Minnesota. Many utilities use Safe Water Commission for program administration.
Why Backflow Testing Matters in Minnesota
Minnesota DLI administers two certifications: BT (testing only, no plumbing license required, ASSE 5110) and BF (testing + repairs + rebuilding, plumbing license + ASSE 5110 + 5130). Annual testing required for all testable assemblies. Test records submitted to water supplier within 30 days. Safe Water Commission is the program administrator for many Metro Twin Cities utilities. The Compliance Engine is used by Shakopee Public Utilities and others. Property managers must confirm which platform their utility uses before scheduling.
Minnesota Backflow Testing Law — The Plain-Language Version
DLI-issued BT (tester) or BF (rebuilder) certification required. ASSE 5110 minimum for BT; ASSE 5110 + 5130 + plumbing license for BF. 30-day test record submission to water supplier.

How Much Does Backflow Testing Cost in Minnesota?
Minneapolis-Saint Paul metro (Minneapolis Water, SPRWS, suburbs): $60 – $140 per assembly.
Rochester, Duluth, St. Cloud, Mankato: $60 – $130 per assembly.
Greater Minnesota (regional cities): $60 – $125 per assembly.
Repair + retest (requires BF holder): $100 – $400+ depending on assembly; BF credential required.
How Long Does Backflow Testing Take in Minnesota?
Standard tests: 25–40 minutes per assembly. Twin Cities metro: 45–70 minutes total. If your assembly fails, you will need a BF-credentialed contractor for repair — not every tester is a BF holder. Confirm before scheduling whether your tester holds BT or BF credentials, and whether they carry common parts for on-site repair.
What to Expect on Test Day
Your tester arrives, locates your backflow assembly (typically near the water meter or service entrance), and connects calibrated differential pressure gauges to the test cocks. Water shuts off for 15–30 minutes during testing. You receive a signed test report immediately. Pass: results are filed with your utility. Fail: the tester identifies the fault and repairs or returns within the required compliance window. Always confirm your tester files results with your utility — request confirmation before they leave.
