What should I do if I have Painted Sprinkler Heads in my facility?

Painted sprinkler heads are required to be replaced. According to the 2008 edition of NFPA 25 – 5.2.1.1.2 – Any sprinkler head shall be replaced that has signs of leakage, is painted (other than by the sprinkler manufacturer), corroded, damaged or loaded; or is in the improper orientation.
