What breaks in a restaurant sprinkler system
Restaurants are hard on sprinkler heads. Heat from the line, grease in the air and a remodel crew with a paint sprayer can all leave a head that won't open the way it was built to, and most owners only hear about it when an inspector or technician points up at the ceiling. These are the repairs we see most often:
- Grease or paint on the head. A coated head gets replaced. Cleaning isn't the fix.
- Leaks. Often the first sign is a drip or a brown stain on a ceiling tile near a head or fitting.
- Bumped or bent heads. Tall shelving, ladders and equipment moves knock them out of position.
- Corrosion. Walk-in coolers and dish areas stay damp, and heads there wear faster.
- Gauges and valves. A gauge that reads wrong, or a valve that won't hold or won't open fully.
- Old heads. Under NFPA 25, heads that have been in service for 50 years must be replaced or sample-tested.
Did your inspection report list deficiencies? Send it over. We can quote from it.
How a repair visit goes
- We find the cause. A dripping head can be a failed head, but it can also be a fitting or pressure problem further up the line.
- If part of the system has to be drained, we tell you before we start. That area is unprotected until the water is back on.
- Replacement heads match the originals in temperature rating, response type and orifice size.
- We restore water and check for leaks. Then we confirm the control valve is open.
A closed valve leaves a building with no sprinkler protection at all, which is why we check it every time. Keep the invoice with your sprinkler records. Your next inspector will want to know what changed.
Van Nuys is LAFD territory
Van Nuys is a neighborhood of the City of Los Angeles, so the Los Angeles Fire Department covers it through its Valley Bureau. County fire doesn't.
Replacing a head with a matching one puts the system back the way it was designed. Changing the system is a different matter. If the repair means moving heads after a kitchen remodel, or adding coverage for a new cook line or walk-in, call the LAFD Fire Prevention Bureau Valley Public Safety Unit at 818-374-1110 before work begins; that office answers plan check questions and handles Fire & Life Safety Inspection Clearances for Van Nuys. Plan check and clearance requests go through the FIMS Customer Portal at inspect.lafd.org. LAFD Fire Development Services also runs a Van Nuys office at 6262 Van Nuys Blvd., 2nd Floor, by appointment only.
Who does the work
In California, our work is done by Hedrick Fire Protection. Hedrick holds C-16 (fire protection) and C-10 (electrical) contractor licenses, and the California State Fire Marshal licenses it under Title 19 for portable extinguisher service and for inspection, testing and maintenance of water-based fire protection systems.
After the repair, routine upkeep takes over. NFPA 25 sets quarterly and annual inspections, and Title 19 adds a five-year service and certification; our restaurant sprinkler inspections in Van Nuys page covers that schedule. The hood suppression system over your cook line is separate. See kitchen fire suppression service.
Restaurant sprinkler repair questions
Can a greasy or painted sprinkler head be cleaned?
Usually not. A coating can change how fast the head reacts to heat, so it gets replaced with a matching head.
Do you come out to inspect and quote, or do you need photos first?
Photos help. Email them with any inspection report to socal@1profire.com, and if the problem needs to be seen in person, we'll set up a visit.
How soon can someone get here?
It depends on that week's schedule. Call with the address and what you're seeing, and we'll give you the earliest open date. If a head is actively leaking, tell us that first.
Does a sprinkler repair need LAFD approval?
A like-for-like head replacement restores the original design. If you're moving heads or adding coverage, ask the Valley Public Safety Unit about plan check first.
