What Is Backflow Repair?
Backflow repair is the service performed when your backflow prevention assembly fails its annual certification test. A failed device means the internal components — seals, springs, check valves, or diaphragms — are no longer functioning correctly and cannot prevent back-siphonage or backpressure from contaminating the public water supply.
Ontario Backflow Tests performs on-site backflow repair for all major brands and assembly types. Our technicians carry a full inventory of repair parts for Watts, Febco, Wilkins, and Ames assemblies, which means we can repair and retest your device in a single visit — no waiting for parts, no return trips.
After completing the repair, we retest the assembly to confirm it passes certification standards, then file your results directly with City of Ontario Utilities or your local water district. Your property returns to compliance in one visit.
Why It Matters
A failed backflow test isn't optional to address. California water districts — including City of Ontario Utilities — require that a failed device be repaired or replaced before the property can be returned to compliance. Delaying repair risks continued non-compliance notices and potential water service shutoff.
For Ontario's commercial and warehouse properties, a non-compliant backflow device creates legal liability and can affect business operations, property insurance, and lease compliance. Fast, on-site repair keeps your property compliant and your operations uninterrupted.
