6. INSPECTIONS, TESTS AND MAINTENANCE
NOTICE: The owner is responsible for maintaining the fire protection system and devices in proper operating condition. For mini-
mum maintenance and inspection requirements, refer to the appropriate standard that describes care and maintenance of sprinkler
systems. In addition, the Authority Having Jurisdiction may have additional maintenance, testing, and inspection requirements that
must be followed.
A. Sprinklers must be inspected on a regular basis for corrosion, mechanical damage, obstructions, paint, etc. The frequency of
the inspections may vary due to corrosive atmospheres, water supplies, and activity around the device.
B. Sprinklers that have been painted, caulked, or mechanically damaged must be replaced immediately. Sprinklers showing signs
of corrosion shall be tested and/or replaced immediately as required. Installation standards require sprinklers to be tested, and
if necessary, replaced after a specified term of service. Refer to the installation standards and the Authority Having Jurisdiction
for the specified period of time after which testing and/or replacement is required. Sprinklers that have operated cannot be reas-
sembled or re-used, but must be replaced. When replacing sprinklers, use only new sprinklers.
C. The sprinkler discharge pattern is critical for proper fire protection. Nothing should be hung from, attached to, or otherwise
obstruct the discharge pattern. All obstructions must be immediately removed or, if necessary, additional sprinklers installed.
D. When replacing existing sprinklers, the system must be removed from service. Refer to the appropriate system description and/
or valve instructions. Prior to removing the system from service, notify all Authorities Having Jurisdiction. Consideration should
be given to employment of a fire patrol in the affected area.
1. Remove the system from service, drain all water, and relieve all pressure on the piping.
2. Using the special sprinkler wrench, remove the old sprinkler and install the new unit. Care must be taken to ensure that
the replacement sprinkler is the proper model and style, with the correct orifice size, temperature rating, and response
characteristics. A fully stocked spare sprinkler cabinet should be provided for this purpose. Follow instructions in section 4.
INSTALLATION.
3. Place the system back in service and secure all valves. Check for and repair all leaks.
E. Sprinkler systems that have been subjected to a fire must be returned to service as soon as possible. The entire system must
be inspected for damage and repaired or replaced as necessary. Sprinklers that have been exposed to corrosive products of
combustion or high ambient temperatures, but have not operated, should be replaced. Refer to the Authority Having Jurisdiction
for minimum replacement requirements.
