Backflow Testing

Backflow prevention protects your drinking water from contamination. When water flows the wrong direction, hazardous chemicals, fertilizers, and bacteria can enter your supply. Our certified technicians use state-of-the-art equipment to test your backflow prevention devices, provide detailed reports, and handle any necessary repairs or replacements on the spot.

The City of Fresno requires annual backflow testing for commercial properties and certain residential properties with irrigation systems, fire sprinklers, or pools connected to the municipal supply, and failure to comply can mean fines or water service disconnection. We keep you compliant with timely testing and file the paperwork with local authorities on your behalf.

A standard test takes just 15 to 30 minutes per device, and testing typically costs between $100 and $150. If a device fails, we carry common parts on our trucks so repairs can often be completed the same day.
