The service cycle for a Downey sprinkler system
A sprinkler system runs on a calendar. The schedule comes from NFPA 25 and California's Title 19. NFPA 25 calls for quarterly and annual inspections, and every five years an internal check of the piping plus replacement or testing of the gauges. Title 19 adds a five-year service and certification, which in California must be done by a contractor licensed by the State Fire Marshal. Mark those dates.
Who checks? Downey has its own fire department. Its Fire Prevention Division, led by an Assistant Fire Chief who is also the Fire Marshal, handles fire and life safety inspections for businesses across the city. Your inspection comes from there.
What a technician checks on a service visit
Most visits start at the riser.
- Control valves: open, secured as required, and able to turn.
- Gauges: current readings, plus age.
- Waterflow and supervisory alarms: does flowing water trip the signal?
- Fire department connection: caps in place, threads clean, access clear.
- Sprinkler heads: no paint, corrosion, damage or storage crowding them.
Under NFPA 25, heads in service for 50 years must be replaced, or a sample sent out for testing. Check the install date. When the visit is done, a tag on the riser records the service date and who did the work.
Repairs between inspections
Parts break between inspections. One Downey caller found a brass part missing from the OS&Y valve on an exterior riser and needed it replaced. An OS&Y valve's exposed stem shows at a glance whether the valve is open, so a damaged or incomplete valve is worth fixing before the next scheduled inspection comes around. Don't wait for the annual. Tell us where the riser is and what's missing.

Which code edition applies
Downey adopted the 2025 California Fire Code, with local amendments, in January 2026. The Fire Marshal described the amendments as mainly organizational. If a lease, insurance letter or older city document you're working from cites the 2016 edition, ask the Fire Prevention Division which edition and amendments apply to your building.
