What your sprinkler system needs, and when
Most sprinkler service starts with a deadline. Maybe the five-year certification is due. Maybe a tag has expired, or an insurer asked for an inspection report.
Inspection, testing and maintenance follow NFPA 25, and California's Title 19 adds a five-year service and certification that only a State Fire Marshal licensed contractor can sign off.
- Quarterly: inspection of valves, gauges and alarm devices.
- Annual: inspection and testing of the whole system.
- Every five years: internal pipe assessment, gauge replacement or testing, and the Title 19 certification.
- At 50 years in service: sprinkler heads are replaced or sample-tested.
Not sure where you stand? Check the tag on the riser. It shows the last service date.
What you get after the visit
The technician walks the system, runs the tests due for that visit and notes anything that failed or looks wrong, such as a painted-over head, a gauge out of range or a valve that won't hold. You get a written inspection report. On a five-year visit, the certification paperwork is completed for your records and for the fire authority. Repairs get listed too.
Adding heads or building a new system is a different job; see our fire sprinkler installation page. Restaurants can also read about restaurant sprinkler inspections.
LA County Fire handles fire service here
Rancho Palos Verdes doesn't run a city fire department. The city contracts with the Los Angeles County Fire Department, whose Battalion 14 provides fire suppression and fire prevention in the city from stations that include Station 53 on Palos Verdes Drive South and Station 83 at Miraleste Plaza.
The city's 2025 code update, which took effect January 1, 2026, brought in the 2025 California Fire Code with local amendments, and the hearing notice also covered adopting the Los Angeles County Fire Code (Title 32). Questions about what your building needs? Ask LA County Fire's fire prevention staff.
Who does the work
California work for 1 Pro Fire is done by Hedrick Fire Protection. Hedrick holds C-16 fire protection and C-10 electrical contractor licenses and is licensed by the California State Fire Marshal under Title 19 for inspection, testing and maintenance of water-based fire protection systems, which includes the five-year certification.

Questions from Rancho Palos Verdes building owners
How often does a sprinkler system need service?
Quarterly, annually and every five years. The five-year visit includes the Title 19 certification.
Is fire flow testing available in Rancho Palos Verdes?
Yes. A fire flow test under NFPA 291 measures how much water the hydrants near a site can deliver, and sprinkler designers and the fire department use it on new construction, even on an empty lot. That's a different job from the yearly NFPA 25 test on a private hydrant; see annual fire hydrant testing.
What should I have ready for the visit?
Your last inspection report, if you have one, and access to the riser and control valves. Tell us if the sprinklers tie into a fire alarm panel, since the alarm devices on the system get tested during the visit too.
