6.2.1.1 (2013) When a sprinkler has been removed for any reason, it shall not be reinstalled.
Handbook: Because of concerns that sprinklers could be damaged during the removal process, this requirement was added to the 2013 edition to clarify that when a sprinkler is removed from the piping it is to be replaced with a new sprinkler. When a sprinkler is removed, damage could occur to the water seal and operating element, specifically a glass bulb type element, which could impact sprinkler performance without any visual indication.
