Restaurant Sprinkler Repair in Diamond Bar

A sheet pan clipped a sprinkler head. Now it's dripping over the prep line. Or maybe the county inspector walked through your kitchen, found heads coated in grease or in overspray from a paint job, and wrote them up with a date to get them fixed. We repair restaurant fire sprinklers throughout Diamond Bar, in both ZIP codes (91765 and 91789).

What breaks in a restaurant system

Kitchens are rough on sprinklers. Grease and steam settle on the glass bulb or fusible element of each head, and a heavily loaded head can open late in a fire, or not at all. Here's what we usually get called to fix:

• Painted or grease-loaded heads. NFPA 25 calls for replacing them.
• Bent heads and cracked glass bulbs.
• Leaks at a head or pipe fitting.
• Heads that have been in service for 50 years, which NFPA 25 says must either be replaced or have samples pulled and sent to a lab for testing.

A replacement head has to match the original's type and temperature rating. Mismatched heads get written up.

How a repair visit goes

Most repairs follow the same order.

1. We trace the cause first. A drip at a head can come from a failing seal in the head itself or from a loose fitting several feet upstream of it.
2. The section is shut down and drained. While the water is off those heads can't operate, so you'll hear from us before the valve closes and can plan the work around your service hours.
3. We replace or repair the damaged parts.
4. Water goes back on. We check the work for leaks and confirm the control valve is open.
5. You get a plain account of what we found. If the visit turns up more work than we quoted, we price it first, and you can decline anything that isn't required to fix the problem you called about.

Who inspects restaurants in Diamond Bar

The city contracts with the Los Angeles County Fire Department for fire protection. Business inspections come from the county's Fire Prevention offices, and the department lists a Diamond Bar office at 1061 S. Grand Ave., phone (909) 569-0758.

Got a correction notice? Have it in hand when you call. The repair should answer each item on it. Re-inspection timing and deadlines come from that office, so ask them.

Who may work on your system

In California, sprinkler service needs a State Fire Marshal licensed contractor. Our California work is done by Hedrick Fire Protection, which 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.

Your hood is a separate system. The wet chemical suppression system over the cooking line runs on its own semi-annual schedule under NFPA 96 and NFPA 17A, and Hedrick is licensed to install and service those too; see our kitchen fire system service in Diamond Bar. We've taken both kinds of calls from Diamond Bar businesses.
