Every line below is in CPSC’s own words, with its source beside it.

What’s wrong with it?

These sprinkler heads can corrode or minerals, salts and other contaminants in water can affect the rubber O-ring seals. These factors could cause the sprinkler heads not to activate in a fire.

What should you do?

Central will provide free of charge replacement sprinkler heads and the labor needed to replace the sprinklers. Central will arrange for the installation by using either its own Central Field Service crews or by contracting with professional sprinkler contractors. Building and home owners should check their fire sprinklers immediately to see if they are part of this voluntary replacement program.

Which ones are recalled?

This replacement program includes two kinds of sprinklers, “wet” and “dry.” “Wet” sprinklers are installed in piping that is filled with water. “Dry” sprinklers are used in areas that may be exposed to very cold temperatures and the exposed piping does not contain water. Central manufactured 33 million “wet” sprinklers with O-rings from 1989 until 2000 that are covered by this program. Central also manufactured 2 million “dry” sprinklers with O-rings from the mid-1970’s to June 2001 that are covered by this program. The program also covers 167,000 sprinklers with O-rings manufactured by Gem Sprinkler Co. and Star Sprinkler Inc. from 1995 to 2001.
