6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements. NOTICE: The owner is responsible for having the fire-
protection system and devices inspected, tested, and maintained in proper operating condition in accordance with this guide, and
applicable NFPA standards. 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 signs of corrosion, mechanical damage, obstructions, paint, etc. Frequency
of the inspections may vary due to corrosive atmospheres, water supplies, and activity around the device.
B. Sprinklers or cover plate assemblies that have been field painted, caulked, or mechanically damaged must be replaced im-
mediately. 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 immediately after a specified term of service. Refer to NFPA 25 and
the Authorities Having Jurisdiction for the specified period of time after which testing and/or replacement of residential sprinklers
is required. Never attempt to repair or reassemble a sprinkler. Sprinklers and cover assemblies that have operated cannot be
reassembled or re-used, but must be replaced. When replacement is necessary, use only new sprinklers and cover assemblies
with identical performance characteristics.
C. The sprinkler discharge pattern is critical for proper fire protection. Nothing should be hung from, attached to, or otherwise ob-
struct the discharge pattern of the sprinkler. 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 effected area.
1. Remove the system from service, drain all water, and relieve all pressure on the piping.
2a. For frame-style sprinklers, use the special sprinkler wrench and remove the old sprinkler by turning it counterclockwise to
unthread it from the piping.
2b. For residential flush pendent and concealed style sprinklers: Remove the ceiling ring or cover plate assembly before unthreading the
sprinkler body from the piping. To remove a ceiling ring, grasp it from below the ceiling and gently turn it counterclockwise. Cover
plates can be removed either by gently unthreading them or pulling them off the sprinkler body (depends on the sprinkler model used).
After the ceiling ring or cover plate assembly has been removed from the sprinkler, use the sprinkler wrench to unthread
the sprinkler from the piping. NOTE: For flush and concealed sprinklers with protective shells, the internal diameter of the
special flush and concealed sprinkler installation wrench is designed for use with the sprinkler contained within the shell.
Place a plastic protective shell (from the spare sprinkler cabinet) over the sprinkler to be removed and then fit the sprinkler
wrench over the shell. Exception: Concealed sprinklers VK457, VK458, VK468, VK474, and VK4570 are removed without
the plastic cap.
3. Follow instructions in section 4B. Installation Instructions to install the new unit. Be sure the replacement sprinkler is the
correct model and style, with the appropriate K-Factor, temperature rating, and response characteristics. A fully stocked
sprinkler cabinet should be provided for this purpose. (For flush or concealed style sprinklers, stock of spare ceiling rings or
cover plates should also be available in the spare sprinkler cabinet.)
4. 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.
