Back-flow Testing

Backflow preventers help protect the drinking-water supply from cross-connection contamination. Testing requirements can depend on the property, device, and municipality. Matrix Mechanical tests and certifies commercial backflow devices, repairs failed assemblies, and keeps equipment records for future service.

Testing and certification

• Scheduled testing of backflow preventers, including reduced-pressure-principle and double-check-valve assemblies
• Test documentation prepared for the applicable property or municipal process
• Device details recorded to make future service and parts identification easier

Repair or replacement

• Diagnosis and repair when a device does not pass testing
• Rebuilds where appropriate and replacement when repair is not practical
• Clear next-step information after the test is complete

What to have ready

• Property address and the contact responsible for the device
• Device type, make, model, and serial number when available
• A previous test report, service record, or notice connected to the request
• Any access instructions or date that matters to the property
• Fixture specifications and any shutdown arrangements relevant to planned work

These details help the team prepare the right records and identify likely device requirements before the visit.
