Backflow Testing
Backflow prevention assemblies protect drinking water from contamination, and many properties are required to have them tested on a regular schedule. If you have received a backflow testing notice, have an annual test due, or have a device that failed, proper testing and documentation matter.

Why Backflow Testing Matters
A backflow prevention assembly keeps non-potable water from flowing backward into the clean water supply. Testing confirms the assembly is working correctly and protecting the drinking water system.
Many water suppliers and local authorities require regular testing for irrigation systems, commercial properties, and other protected connections. Staying current with testing helps keep the property in compliance and the water supply protected.
Who Needs Backflow Testing
Backflow testing is commonly required for irrigation and sprinkler systems, commercial and industrial properties, fire protection systems, and other connections identified by the water supplier or local authority.
If you received a testing notice or compliance reminder, have an annual test due, or manage a property with a protected connection, the assembly likely needs to be tested by a qualified tester and documented.
Our Testing and Documentation Process
Wills Plumbing & Testing Service inspects the device type, location, accessibility, and visible condition, then performs the required test according to the applicable testing procedure.
We document the results clearly and provide the reporting information needed for your records or for submission to the water supplier or authority.
Failed Backflow Test: What Happens Next
If an assembly fails testing, it may not be protecting the water supply correctly. A failed result usually means the device needs repair or, in some cases, replacement, followed by retesting to confirm it passes.
Wills Plumbing & Testing Service explains the failed result, recommends the appropriate repair next steps, and can coordinate retesting once the work is complete.
Backflow Repair Recommendations
Backflow assemblies can be affected by freeze damage, worn or failed valves, fittings, or installation issues. After testing, Wills Plumbing & Testing Service explains any visible repair concerns and the recommended next steps based on the condition of the device.
Repair and retesting are coordinated so the assembly can be returned to a passing, compliant condition.
Why Licensed Plumbing Experience Matters
Backflow testing is a compliance and safety service that requires proper testing procedure, accurate documentation, and sound repair judgment. Doing it correctly protects the water supply and keeps the property in good standing.
