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.

"They installed a 100 foot pipe, 15 feet down with a 45 degree turn. It was an incredibly huge job. The job was done professionally, fast, efficiently and successfully. Joe and Orlando were professional, helpful and always there to answer my questions."

Dorrie N. via yelp

"I failed an inspection required by City of San Mateo's lateral sewer line ordinance. Joe gave me a quote with a few contingencies for what he could not see until excavating, and the contingent items were not necessary, so the quote held. Permits and all phases were perfectly sequenced, and we passed inspection."

David F. via yelp

"An excellent experience working with Joe on my water service, city side upgrade. He went above and beyond to push the project through, even as the city changed the sequence and timing of several technical and administrative steps. His communication and follow through were exceptional."

A Ying T. via yelp

"Joe was up front about cost and schedule, and was careful to make sure that the job was truly necessary. His crew was thorough, prompt, and great to interact with. They rolled with some unexpected hiccups on our end."

Christopher B. via google

"We needed a pipe dug out of a concrete driveway in order to clear the sewer line. Joe explained everything and the work was done in one day."

Rich B. via yelp

"They came out to assess the situation and proposed a cost effective solution. They drove out that night to get the sewer line into a passable condition so we would not be without water, free of charge. During the project they had four guys working and completed the sewer line replacement in a single day."

Yuda Z. via yelp

"I had a leak under my house and Joe came out within hours. They replaced galvanized pipes within 24 hours, very professional."

Robert S. via yelp

"Our old galvanized water lines were badly corroded and needed replacing with copper. They were prompt and knowledgeable, got the work done with minimal inconvenience, and constantly kept us advised what was being done."
