Backflow Preventer Installation
New construction, an unrepairable device, an updated purveyor requirement, or an unprotected fire or irrigation line all call for a properly sized, code-compliant assembly. We install RP, DC, and PVB devices under our C-36 license and certify the work.
When Installation Is the Right Call
Replacement is the correct path when a device has failed repair, when parts are no longer available, or when a water purveyor updates its cross-connection control requirements and the existing assembly no longer meets code. New installs are also common on new construction, fire service lines, irrigation systems, and any point where a potable water line connects to a source of potential contamination.
What Our Backflow Installation Service Covers
Device type and size are matched to the hazard classification and flow demand of the connection before we order equipment.
Installation follows California Plumbing Code clearance, elevation, and orientation requirements.
We install assemblies on fire service lines, irrigation systems, and domestic service connections.
Enclosure and freeze or flood protection are planned into the installation where the site calls for it.
We handle permits, device approval, and advance notice with your water purveyor so the installation is accepted the first time.
Our ABPA-certified testers perform the initial certification test and submit passing results so the assembly is active on the purveyor’s record.
