Accurate Backflow Testing

Annual Accurate Backflow Testing

Annual Accurate Backflow Testing protects potable water and keeps your property compliant with Michigan requirements. When you schedule Annual Accurate Backflow Testing with Backflow Prevention Services, a certified tester, also a licensed plumber in Michigan, verifies that each backflow prevention assembly is operating within specification, documents the results, and submits your certificate to the authority. Use this guide to understand scope, roles, and outcomes so your Annual Accurate Backflow Testing is simple and predictable every year.

Why accuracy matters

Accurate Backflow Testing confirms that check valves and relief mechanisms in a backflow prevention assembly still function properly after months of temperature swings, pressure changes, and normal wear. Precision protects public health, prevents costly re-tests, and provides clean documentation for audits.

What we test and document

• Confirm assembly make, model, size, serial number, and installation details
• Perform calibrated gauge procedures per ASSE 5110
• Record differential pressure readings and pass/fail status
• Provide a signed test report and submit the certificate to the authority having jurisdiction

Michigan specifics you should know

• Annual testing is standard across Michigan communities
• Testing must be completed by a certified tester
• In Michigan, certified backflow testers are licensed plumbers, which means they can legally repair. Real quality comes from hands-on diagnostics, correct parts selection, and careful retesting

What happens if an assembly fails

Failure does not always mean replacement. Our workflow is to diagnose the issue, provide a clear written quote, and return once approved to complete repairs and retesting. Same-day repairs are uncommon because many assembly models and parts are in circulation and the right components must be used.

Your role on test day

• Provide safe access to each assembly and approve water-off windows
• Coordinate onsite contacts so spaces can be entered on schedule
• Arrange any temporary water or bypass solutions you require; these are the customer’s responsibility

Residential notes for Michigan

• Typical residential assemblies: PVB for irrigation backsiphonage only, or RPZ where hazard, elevation, or backpressure risk warrants it
• Some Michigan municipalities require an RPZ on water-driven sump pumps
• Coordinate irrigation winterization and line work with your irrigation contractor; we do not blow out lines

Portfolio and multi-site programs

• Centralize certificates, test dates, and assembly inventory
• Stagger annual testing across locations to avoid deadline spikes
• Standardize assembly models during replacements to simplify stocking and service over time

What you receive after testing

• A complete report with readings and pass/fail outcomes
• Certificate submission to the authority on your behalf
• Reminder scheduling so next year’s date is never missed
