What your sprinkler system needs, and when
Sprinkler calls are the most common kind we get from Diamond Bar. In California, Title 19 and NFPA 25 set the schedule. It runs like this:
- Every quarter: an inspection.
- Every year: the annual inspection and testing.
- Every five years: an internal assessment of the piping, replacement or testing of the gauges, and the five-year service and certification that Title 19 requires.
- Heads at 50 years: replace or sample-test.
Sprinkler heads carry a year-of-manufacture marking, so a technician can usually tell you how close the older heads in your building are to that 50-year mark.
What happens on a service visit
A technician walks the system from the riser out. They check gauge readings, control valve positions (and whether each valve is locked or supervised), the alarm devices, and the heads themselves for paint, corrosion, damage or storage stacked too close. Painted or corroded heads get flagged. The annual visit adds testing, such as flowing water through the inspector's test connection to confirm the water flow alarm sounds as it should. Expect some water on the ground.
Who inspects Diamond Bar businesses
Diamond Bar contracts with the Los Angeles County Fire Department, so the county department is the city's fire department. Business inspections and plan check here go through LACoFD Fire Prevention. Its Diamond Bar office is at 1061 S. Grand Ave., (909) 569-0758.
If a fire inspector has flagged your sprinkler system, send us the notice or read it to us over the phone, and we'll quote the work it lists.
Who may service your system
In California, sprinkler inspection, testing and the five-year certification have to be done by a contractor licensed by the State Fire Marshal. Our California work is done by Hedrick Fire Protection. Hedrick holds C-16 (fire protection) and C-10 (electrical) contractor licenses and is State Fire Marshal licensed under Title 19 for inspection, testing and maintenance of water-based fire protection systems. That includes the five-year certification.
Adding heads or a new system is a separate job, covered on our page about fire sprinkler installation in Diamond Bar. Other services in the city are listed on the Diamond Bar fire protection hub. Own buildings elsewhere? We also do fire sprinkler service across Los Angeles County and fire sprinkler service in San Bernardino County.
General service questions
These come up on service calls of all kinds, not only sprinkler visits.
Do you issue a certificate after the service?
Yes. The five-year service that Title 19 requires is certified by the licensed contractor who performs it, so keep that certification with your building's fire protection records for the inspector.
Can the final price change?
It can. If the technician finds the system needs more maintenance than the quote covered, the price changes to cover that work.
Can I decline extra work the technician recommends?
Yes. Recommended extra work isn't required, so you can turn it down if it costs more than you want to spend.
Do you take cards?
Yes, we accept card payments.
