How to Choose a Certified Backflow Tester in Rochester MN

Your backflow preventer is a critical safety device that protects your drinking water from contamination. The person who tests it needs to be qualified, thorough, and trustworthy. A subpar tester might rush through the process, miss developing problems, or submit inaccurate results — leaving you vulnerable to both device failures and regulatory non-compliance.

Conversely, a skilled professional will not only test your device accurately but will also identify potential issues, recommend preventive maintenance, and help you maintain a reliable compliance record. For property owners in Rochester, Byron, Stewartville, and Kasson, finding the right tester is one of the most important decisions you'll make for your property's water safety.

In Minnesota, backflow testing can only be performed by individuals who hold a valid backflow tester certification. Here's what to look for:

Minnesota Backflow Tester Certification: All testers must be certified by passing an examination that covers backflow theory, device types, testing procedures, and applicable codes. This certification must be maintained through continuing education and periodic re-examination (typically every two years).

What to verify: - Ask to see the tester's current certification card - Verify the certification number with the state if you have concerns - Confirm the certification is current (not expired) - Check that the tester is certified for the specific type of device you have

Additional credentials to look for: - Licensed plumber (not required for testing, but indicates broader expertise) - Manufacturer-specific training certifications - ASSE (American Society of Sanitary Engineering) certifications - Insurance coverage (liability insurance is essential)

RPU maintains a list of testers who have submitted valid test reports in their service area. While not a formal endorsement, this can be a useful reference for finding active, experienced testers in the Rochester area. Learn more about why this matters in our guide on what backflow testing involves.

Don't just hire the first name you find. Ask these questions to ensure you're getting a qualified professional:

1. "Are you currently certified to test backflow preventers in Minnesota?" — This is non-negotiable. No certification means no legal testing.

1. "How long have you been testing backflow devices?" — Experience matters. A tester with 5+ years has likely encountered every device type and situation.

1. "Do you carry liability insurance?" — Protect yourself in case of accidental damage during testing. Ask for the insurance amount.

1. "Will you submit the test report directly to RPU?" — Most reputable testers handle this automatically. If they don't, it creates extra work and risk for you.

1. "What does your testing fee include?" — Understand exactly what's covered. Compare this to the typical backflow testing costs in the Rochester area.

1. "Can you perform repairs if the device fails?" — A tester who can both test and repair saves you from scheduling a second visit. Not all testers are authorized to make repairs.

1. "Do you offer annual reminders?" — This is a valuable service that helps you stay on your testing schedule without having to track dates yourself.

1. "What's your availability and typical scheduling timeframe?" — During busy season, popular testers may be booked weeks out. Planning ahead is important.

1. "Do you have experience with my device type?" — Especially important for commercial properties with large or specialized devices.

1. "Can you provide references from other Rochester-area clients?" — A confident professional will happily share references.

Be cautious of testers who exhibit any of these warning signs:

• Cannot produce a current certification card — Walk away immediately. An uncertified test is invalid and you'll need to pay for a retest.
• Unusually low pricing — If someone quotes significantly below the typical range ($75-$200), they may be cutting corners on the testing process.
• Rushing through the test — A proper backflow test takes 15-30 minutes per device. If someone is done in 5 minutes, they're not performing a thorough test.
• No test equipment visible — Professional testers use specialized differential pressure test kits. If they show up without equipment, something is wrong.
• Won't provide a written test report — You should receive a copy of the official test report for your records. This document is your proof of compliance.
• Pressuring unnecessary repairs — While some repairs are genuinely needed, be wary of testers who find expensive problems on every visit. Get a second opinion if something feels off.
• No insurance — Uninsured testers expose you to liability risk if something goes wrong during testing.
• Won't submit results to RPU — Leaving report submission to the property owner creates risk of missed deadlines and non-compliance.
• Negative reviews or complaints — Check online reviews and ask RPU if they've received complaints about the tester.

A quality backflow tester will follow a consistent, professional process:

Before Testing: - Arrive on time and introduce themselves - Show their certification if requested - Locate and visually inspect the device - Explain the testing process and expected duration - Note the device type, manufacturer, model, and serial number

During Testing: - Connect calibrated test equipment to the device test cocks - Systematically test each check valve and the relief valve (for RPZ devices) - Record precise pressure readings for each test point - Complete the entire testing protocol without shortcuts - Briefly interrupt water service only as needed

After Testing: - Discuss the results with you - Provide a copy of the test report - Explain any issues found and recommend repairs if needed - Submit the report to RPU - Schedule the next annual test if you'd like

If your device fails, a good tester will explain the specific problem, provide a repair estimate, and discuss whether repair or replacement is the better option. They should never pressure you into immediate repairs — you have the right to get a second opinion.
