Recalled sprinkler heads in 1990s and 2000s tract homes
Fontana, Rancho Cucamonga, Corona, Temecula, Moreno Valley and the High Desert all filled up with sprinklered tract homes between 1990 and 2007. A large share of those houses got heads that were later recalled, and most owners never heard about it. Here is what the two recalls covered, how to check your ceiling, and what the fix looks like today.
Why this matters in the Inland Empire
On October 19, 2009 the Fontana Fire Protection District mailed every resident a letter titled Recalled Fire Sprinkler Heads. It said many of the city's sprinkler systems were installed with Central brand Omega heads, that some owners never took advantage of the recall, and that there had been recent fires in Fontana where recalled heads failed to operate. The chief asked owners to check their heads and, if they found Omegas, to replace them immediately.
Fontana is not special. The same builders, the same sprinkler subcontractors and the same product lines served tracts across both counties in the same years. If your house was built between about 1990 and 2007 and it has sprinklers, this page is worth ten minutes.
Recall one: Omega heads, 1998
On October 14, 1998 the Consumer Product Safety Commission and Central Sprinkler Corporation recalled about 8.4 million Omega brand heads made since 1982. In the CPSC testing that led to the recall, between 30 and 40 percent of Omegas pulled from buildings around the country did not activate. The commission counted 17 fires since 1990 where Omegas failed, with at least four injuries and more than 4.3 million dollars in property damage (figures from the Fire Engineering report on the recall).
The problem was a rubber O-ring seal that could degrade over time and hold the head shut. Central offered free glass bulb replacement heads and help with removal cost. Per the Fontana letter, that cost assistance ended before August 2007.
Recall two: Central, Gem and Star O-ring heads, 2001
On July 19, 2001 the CPSC and Central announced a much larger program covering 35 million heads: 33 million wet heads made from 1989 through 2000, 2 million dry heads made from the mid 1970s through June 2001, and about 167,000 heads sold by Gem Sprinkler Company (1995 to 2001) and Star Sprinkler (1996 to 1998). Same failure mode. Corrosion, or minerals and salts in the water, could attack the O-ring and keep the head from opening in a fire. Inland Empire water is hard, which is exactly the condition the notice describes.
Central provided free replacement heads and labor. That program ended on August 31, 2007. Any head from those lines still in a ceiling today is the owner's problem to fix.
How to read a head
Stand on a step stool with a flashlight and look at the metal frame and the deflector (the small plate the water hits). Do not touch the bulb or the link, and do not unscrew anything. The CPSC notice lists these markings for the O-ring recall:
- CENTRAL or the letters CSC stamped on the frame or deflector.
- STAR or a star shaped symbol.
- The letter G inside a triangle (Gem).
Omega heads are a Central product with the Omega name in the model designation, and the Fontana letter came with a photo because the shape is distinctive once you have seen one. If you have a spare head box in the garage from the builder, the model is printed on it. Concealed heads with a flat cover plate are harder to read without pulling the plate, which is a contractor task.
If you are not sure, take a clear phone photo of one head and send it with your quote request. A contractor who works these tracts recognizes the recalled lines on sight.
What the fix looks like
Replacement is a set job, not a one head job. The contractor drains the system, swaps every head for a current listed residential head with matching orifice and temperature rating, refills, checks for leaks, and records the date. A typical Inland Empire tract home has somewhere between 15 and 30 heads, so it is a half day of work for a two person crew. The price is set by the contractor and is mostly parts and one visit. This is the same trade and the same visit that handles painted heads and the periodic inspection, so owners often bundle them.
While the system is drained, ask for the control valve to be checked and tagged. A closed valve is the other quiet failure in older tracts, and it costs nothing to confirm while someone is already at the riser.
Selling or buying a 2000s tract home
Home inspectors in Riverside and San Bernardino counties rarely read sprinkler heads. If you are buying a sprinklered house from this era, put a line in your inspection request for the head make and model. If you are selling, a receipt for a full head replacement removes a question from the buyer's list. The repair page covers the other findings that show up in the same walk through.

Questions people ask
Is the free replacement program still running?
No. The CPSC recall notice states the Central O-ring replacement program ended on August 31, 2007, and the Fontana Fire District letter from October 2009 says the Omega cost assistance stopped before August 2007. Replacement today is a normal repair job priced by the contractor.
My house was built in 2004. Could it still have recalled heads?
Yes. The O-ring recall covered Central wet heads made from 1989 through 2000 and dry heads up to June 2001, and a 2004 house could have been built from stock on hand. The only way to know is to read the frame or deflector of a head, or have a contractor look.
Can I just replace the one head that looks bad?
The recall reasoning applies to every head from the same batch, not the one that happens to be visible. Contractors replace the whole set so the house is on one generation of listed heads with one test date.
Do I need a permit to swap the heads?
Replacing heads one for one with the same performance characteristics is maintenance under NFPA 13D chapter 4 as summarized by Riverside County Fire. Some fire authorities still want to be told about a whole house replacement. The contractor who does the work knows the local answer.
