What Is Backflow Installation?
Backflow installation is the professional installation of a new backflow prevention assembly on a property that currently has no device, or requires an additional assembly for a new water connection or use. California law requires backflow prevention assemblies on most commercial, industrial, and multi-family residential properties, as well as residential irrigation systems.
Ontario Backflow Tests installs all types of backflow prevention assemblies: double check valves (DCV), reduced pressure zone assemblies (RPZ/RPBA), pressure vacuum breakers (PVB), and spill-resistant vacuum breakers (SVB). We install devices that meet City of Ontario Utilities specifications and the requirements of all 12 water districts in our service area.
After installation, we perform the initial certification test and file your results with your water district — starting your property's compliance record from day one.
Why It Matters
New construction, property renovations, changes in water use, and new irrigation system installations all commonly trigger backflow assembly requirements from City of Ontario Utilities. Installing the wrong type or size of assembly — or failing to file the initial certification — can delay your project and result in failed inspections.
Ontario's active commercial and industrial development creates steady demand for new backflow installations. Warehouse expansions, food processing facilities, fire suppression system upgrades, and commercial landscaping projects all require properly specified and certified backflow assemblies. We understand these requirements and ensure your installation is compliant from the start.
