Backflow Testing, Repair & Installation in Ontario, CA
Certified backflow services for Ontario properties on regularly scheduled routes — testing, same-visit repairs, and your the City of Ontario paperwork filed for you. $450 minimum visit; bundle devices to make it count.
Serving Ontario Since 2007
If the City of Ontario has mailed you an annual backflow test notice, Atlas Backflow can test, certify, and file your results with the city. We schedule regular Inland Empire runs.
We maintain 25 devices in Ontario and run Inland Empire routes regularly — the massive logistics and distribution campuses around Ontario International Airport, Ontario Mills-area retail, and industrial properties along the 60 and Mission corridors. Warehouse fire lines and large RPs are core work for our crews. Bundling multiple devices or sites onto one visit stretches the trip charge — ask about coordinating.
And if your device fails? Our trucks carry a full parts inventory, so most Ontario repairs happen on the same visit — with re-certification included when we do the repair. We also build and install custom anti-theft cages, an increasingly common need for exposed commercial assemblies around Ontario.
Ontario Testing: $450 Minimum Visit
All device types — DCVA, PVB, RP/RPZ, SVB, fire lines. The minimum covers travel and scheduling; testing multiple devices on one visit makes it go further. Compliance documentation and district submittal included.
