Recalled Sprinkler Heads Are Still in Buildings: How to Check Yours
CPSC and Tyco Fire Products alerted the public on September 24, 2026 that Central Sprinkler O-ring heads recalled in 2001 may still be installed in homes and commercial buildings. The replacement program closed in 2007, so identification now depends on building records and a qualified inspector.

The U.S. Consumer Product Safety Commission and Tyco Fire Products issued a public alert on September 24, 2026 about fire sprinkler heads recalled in 2001 that may still be installed in homes, apartment buildings, care facilities and commercial properties. The heads use a rubber O-ring seal that minerals and salts in water can degrade, and a degraded seal can stop the head from opening during a fire. The replacement program that covered them closed in 2007. Nobody checks buildings automatically, and the manufacturer no longer sends replacement heads.
What the alert actually covers
The affected products are Central Sprinkler fire sprinkler heads with O-ring seals, along with a limited number of O-ring models sold by Gem Sprinkler Company and Star Sprinkler, about 167,000 heads in total. The 2001 notice put the Central total at 35 million heads.
Central made roughly 33 million wet heads, the type installed in piping that stays filled with water, between 1989 and 2000. It made about 2 million dry heads, used where exposed piping can freeze, from the middle of the 1970s until June 2001.
The alert draws no line between sprinklered houses, apartment blocks, hospitals, schools, dormitories, nursing homes, day care centers, supermarkets, parking garages, warehouses and offices. The 2001 announcement listed all of them, so owners of these buildings still have reason to check which sprinkler models are installed.
Why a 2001 recall is being raised now
The July 2025 fire at an assisted living facility in Fall River, Massachusetts killed ten residents and injured dozens more. CPSC says the facility still had dozens of recalled sprinkler heads that an earlier fire safety inspection had already identified.
The written reason for the recall is narrow and mechanical. Rubber O-rings seal the water path inside the head, and contaminants in the water supply attack that rubber over years. A head that has lost its seal may not open at all when a fire raises the temperature around it, or it may need more water pressure than some buildings can deliver. Laboratory testing in 2001 found that most of the recalled heads would still work, which is why the alert describes a population of heads instead of a guaranteed failure.
These heads have now been in ceilings for 25 to 50 years. When the replacement program opened in 2001, Central had 13 reports of O-ring heads failing to open in a fire, four involving wet heads and nine involving dry heads.
How to tell whether a building still has them
The check runs head by head, because the failure cannot be seen from below. CPSC published the physical marking scheme in 2001: the words CENTRAL or STAR, the letters CSC, a letter G inside a triangle, or a star shaped symbol, stamped onto the metal frame or the deflector. The deflector is the flower or gear shaped metal part at one end of the head, and a model designation and a date may also be stamped on the frame or the deflector.
The model list matters as much as the markings, because a manufacturer stamp alone does not prove that a head was part of the replacement program. CPSC attached the covered model list to the end of its recall notice and referred owners to material that identified heads. Tyco still links an identification guide and a list of suitable replacement heads from its notice page.
Documents come first. Inspection and maintenance reports for a sprinklered building record sprinkler models, and Tyco states that records of the model numbers present at a facility plus visual identification together can determine whether affected heads are installed. Anyone holding an inspection report, a commissioning file or a set of contractor invoices can start with those, then have a qualified fire protection professional confirm what is in the ceiling.
If the heads are still there
CPSC and Tyco ask for inspection, replacement by a qualified fire protection professional, a review of historical maintenance records to confirm whether recalled units were identified and removed, and notification of everyone responsible for the building, including managers, boards and facility administrators.
A sprinkler head cannot be judged by looking at it. The O-ring sits inside the head, out of reach of any check made from the floor, so identification runs on paper and part numbers.
The heaviest obligation falls on older buildings that house people who cannot evacuate on their own, which is why the alert names nursing homes, hospitals and schools alongside houses and offices.
Replacement is a planned job with a real cost. Every affected head is a part that has to be bought and installed, and the work happens head by head across a ceiling. Anyone budgeting for it should treat the identification report as the document that defines the scope.
What ended in 2007, and what it means for the bill
In 2007 CPSC announced that the voluntary replacement program would close on August 31 of that year, and that property owners had to get Proof of Claim and Waiver and Release of Claims forms to Central Sprinkler Company with a postmark by that date. Valid claims received before the deadline qualified for free replacement heads and installation.
Central provided replacement heads and the labor at no charge, and from 2003 owners could hire their own contractor and seek full or partial reimbursement for labor after notifying Central in advance, verifying the work and returning the removed heads. In the 2007 notice the agency told owners to consult their sprinkler installer or check system records, and warned that incomplete claims had to be completed by the same deadline or they would be void.
The current alert does not say that a replacement route exists. Nothing in the September 2026 material offers new parts, new labor or new reimbursement. Tyco's FAQ tells building owners and their representatives to review records, consult licensed fire protection professionals, and replace affected sprinklers in line with applicable standards and codes. It does not say who pays.
What a resident can ask for
A tenant, family member or condo owner cannot inspect a sprinkler head from the floor, and no public database maps recalled heads to addresses. The realistic move is a records request. Under the standard that governs water based fire protection systems, NFPA 25, the owner or a designated representative carries the responsibility for inspection, testing, maintenance and replacement of system components. Tyco's FAQ states that NFPA 25 does not require inspectors to hunt for recalled heads during routine service, but that when an inspector identifies a recalled component the standard calls for that finding to be reported to the owner in writing.
That written report is the document to ask for. A building with sprinklers should have periodic inspection records, and those records are where a recalled model number would surface. Residents of a building that houses people with limited mobility have the strongest reason to ask, given the Fall River findings.
CPSC keeps its consumer hotline at 800-638-2772 for recall questions. For an owner who has never checked, the agency's 2007 advice still stands: consult the sprinkler installer or read the system records first.

What is still not known
Nobody has published a current count of unremediated heads, the number of buildings that still contain them, or the share of the original 35 million that was replaced before the program closed. The FAQ also leaves open what happens when an owner identifies affected heads and cannot fund replacement, and whether any regulator will require identification of recalled heads as part of routine inspection in future editions of the standard.
