Fire line backflow preventers are a required component of any fire suppression system connected to a public water supply. They protect the potable water supply from contamination caused by pressure fluctuations in the fire line — and failure to install or maintain them properly can result in system shutdown and code violations. Total UC provides certified fire line backflow preventer installation throughout the Bay Area, ensuring your system meets NFPA 13, NFPA 24, and local water district requirements.
Fire Line Backflow Services We Provide
Our fire line backflow services include reduced pressure detector assembly (RPDA) installation, double detector check assembly (DDCA) installation, backflow preventer sizing and placement per system hydraulics, permit acquisition and AHJ coordination, hydrostatic pressure testing, and annual testing and certification reporting to your local water authority.
Certified Backflow Specialists Serving the Bay Area
Total UC's certified testers serve property owners, facility managers, and fire sprinkler contractors throughout Alameda, Contra Costa, San Mateo, and Santa Clara counties. We coordinate with EBMUD, Cal Water, and other local water districts to ensure compliance. Call 415-350-3363 for fire line backflow installation or testing services.
Customer Reviews
What Our Clients Say
Trusted by homeowners, developers, and municipalities across the Bay Area.
"Joe was friendly and professional. He fixed my water pressure problem within 20 minutes and followed up the next day."
"They completed sewer line replacement in one day at a reasonable price. Went above expectations with free prep work."
Our Process
How It Works
Three straightforward steps from first call to finished project.
Diagnose & Inspect
We assess the project site, review plans, and use camera inspection or utility locating to understand exactly what's underground before we touch anything.
Quote & Plan
You receive a clear, itemized estimate with no surprises. We handle permits, coordinate with utilities, and schedule the crew around your timeline.
Service & Cleanup
Our self-performing crews complete the work to spec and code. Site is restored and cleaned up — we don't leave until the job looks right.
