Our Process
How It Works
Site Assessment
We evaluate your water system connections, identify the hazard level, and determine the correct type of backflow device required by your local water purveyor.
Device Selection & Permitting
We specify the appropriate assembly, obtain plumbing permits, and coordinate with the water purveyor on placement and configuration requirements.
Installation
Our crew installs the backflow device above ground per manufacturer and jurisdictional requirements, including proper clearances, strainers, and test ports.
Testing & Filing
We perform an initial test, certify the device, and file the required test report with your local water purveyor to establish compliance.

FAQ
Frequently Asked Questions
A backflow prevention device is a mechanical assembly installed on a water line to prevent contaminated water from flowing backward into the public water supply. They are required by law wherever a cross-connection exists between a potable water system and a potential source of contamination.
California requires annual testing of all backflow prevention assemblies by a certified tester. Your local water purveyor will send a notice when testing is due. We handle the test and file the results directly with the purveyor on your behalf.
Yes. We specialize in above-ground backflow prevention installations, which are the current standard required by most Bay Area water purveyors. Above-ground installations are easier to test, maintain, and inspect compared to vault-mounted assemblies.
Water purveyors can issue violation notices, impose fines, or in severe cases shut off water service to non-compliant properties. We can bring your property into compliance quickly with the correct device installation and certified testing.
We install RPZ (Reduced Pressure Zone) assemblies, DCVA (Double Check Valve Assemblies), PVBs (Pressure Vacuum Breakers), and detector assemblies for fire lines. The correct device depends on the hazard level and the requirements of your local water purveyor.
