NFPA 13D 2002, para. A1-4: The responsibility for properly maintaining a sprinkler system is that of the owner or manager, who should understand the sprinkler system operation. A minimum monthly maintenance program should include the following:

  1. Visual inspection of all sprinklers to ensure against obstruction of spray.
  2. Inspection of all valves to ensure that they are open
  3. Testing of water flow devices
  4. Testing of the alarm system, when installed
  5. Operation of pumps, where employed. (See NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection.)
  6. Checking of the air used with dry systems.
  7. Checking of water level in tanks.
  8. Special attention to ensure that sprinklers are not painted either at the time of installation or during subsequent remodeling. When sprinkler piping or areas next to sprinklers are being painted, the sprinklers should be protected by covering them with a bag, which should be removed immediately after painting is finished.
