Hello My name is Sal Lorta and I am the facilities Coordinator for Sacramento County Office Of Education. National Fire Co. has provided the best service for fire suppression systems over my career and has saved us time and money with their service. We had a previous service co. onsite at our H.S. and they stated the mechanical water gong for the fire system was old and needed replacement after a half hour visit and no hand tools where ever used? they stated engineering would be needed and permits pulled etc. The cost and time was going to be $$$. I remembered in my previous employment with another school district using National Fire Co. and decided to reach out to them for good measure. they dispatched Technicians Manuel and Gabriel, both arrived and went to work with on the water gong with tools and skilled knowledge, the water gong was working in 1/2 hour and continues to work today! and when on campus performing tests the water gong is sounding and is a testament to their honest service. The office staff Kia and Sara, Tricia are always assisting us with answers and service schedules that work for us. Francisco/Travis can always be counted for troubleshooting and servicing technical concerns. The company works as a team and provides the best support for their customers! 5 stars for National Fire Service! Thanks for all the assistance over the years!

Damaged private fire hydrant with exposed rusted piping and open valve box needing repair

Comprehensive Fire Hydrant Flow Testing & Inspection

Maintaining reliable fire hydrants requires regular static, residual, and flow pressure measurements along with detailed mechanical servicing.

Following NFPA 291 (Recommended Practice for Fire Flow Testing and Marking of Hydrants), NFPA 25 standards, and California Title 19 mandates, our testing protocols provide precise water supply data and ensure complete system readiness:

  • Hydraulic Fire Flow Testing: Executing pitot tube and gauge measurements using pitot diffusers or specialized equipment to record static pressure (PSI), residual pressure (PSI), and discharge flow (GPM).

  • System Design & Engineering Support: Delivering certified flow test data and hydraulic curves required by fire protection engineers, architects, and contractors for designing new fire sprinkler or standpipe systems.

  • Operational Flushing & Debris Clearance: Controlled flushing of private fire mains and hydrants to remove rust, sediment, and obstructions that compromise water delivery and damage downstream valves.

  • Mechanical & Visual Inspections: Thorough examination of operating nuts, nozzle threads, caps, gaskets, pumper outlets, barrel integrity, and drain valve functionality to prevent freezing or subterranean leaks.

  • Color-Coding & Marking: Categorizing and painting hydrants in accordance with NFPA 291 standard color-coding schemes based on measured GPM capabilities for immediate firefighter identification during an incident.

  • Deficiency Repairs & Maintenance: Expert repair services for leaking stem packing, broken operating stems, damaged nozzle threads, missing caps, and buried valve boxes.

  • AHJ Compliance Reporting: Compiling official water supply test reports submitted directly to local Authorities Having Jurisdiction (AHJs)—including the City of Sacramento Fire Dept., Sac Metro Fire Dept., and Elk Grove Cosumnes Fire District—and insurance providers.
