The recall was announced after receiving reports of Omega sprinklers not functioning in several fires, resulting in millions of dollars in damages as well as injuries. As of 2009, there have been several such failures documented within the City of Fontana, indicating that there are potentially many of these Omega sprinkler heads in homes just like yours.
The Fontana Fire District recently sent out a letter on October 19, 2009, notifying all residents who may not be aware of this issue. View the letter online in English or en Español).
Why Omega Sprinkler Heads are Defective
Central Omega heads are one of several models of sprinkler heads in which the design includes a rubber O-ring seal that has been shown to degrade over time. This in turn prevents a plug in the sprinkler head from being pushed out and allowing water to spray out. In some cases, these sprinkler heads were directly above a fire and still failed to operate.
