Below is the language in 13D/2016 regarding maintenance. It is substantially, if not exactly the same as 2013. I left out section 12.3.5 as that addresses anti-freeze only. I suppose if you wanted to add the "test after twenty years" to the "what information SHOULD the contractor provide" part, you could. 12.1* General. The installer shall provide to the owner/occupant instructions on inspecting, testing, and maintaining the system. 12.2* Inspections and Tests. The sprinkler system shall be inspected and tested periodically to make sure the system is in good working condition. 12.3 Maintenance. 12.3.1 The sprinkler system shall be properly maintained in accordance with this standard and the manufacturers’ instructions. 12.3.2 Any sprinkler that is operated, damaged, corroded, covered with foreign materials, or showing signs of leakage shall be replaced with a new listed sprinkler having the same performance characteristics as the original equipment. 12.3.2.1* Where replacing residential sprinklers manufactured prior to 2003 that are no longer available from the manufacturer and are installed using a design density less than 0.05 gpm/ft2 (204 mm/min), a residential sprinkler with an equivalent K-factor (± 5 percent) shall be permitted to be used provided the currently listed coverage area for the replacement sprinkler is not exceeded. 12.3.3 Painting Sprinklers. 12.3.3.1 Sprinklers shall not be painted unless applied by the manufacturer. 12.3.3.2* Any sprinklers that have been painted outside of the factory shall be replaced with a new listed sprinkler. 12.3.4* Wet Pipe Systems. A wet pipe system shall be maintained above 40°F (4°C), including areas properly insulated to maintain 40°F (4°C). A.12.1 These instructions should include the following: (1) Information regarding the necessary system inspection, testing, and maintenance as described in this standard (2) The manufacturers’ installation, care, and maintenance instructions for the installed sprinkler system components (3) Name, address, and phone number of the installing contractor of the fire sprinkler system (4) Name, address, and phone number of a fire sprinkler system service company if different than the installing contractor The occupants of a home with a sprinkler system should understand that maintaining a sprinkler system is mostly about common sense. Keeping the control valve open, not hanging items from the sprinklers, and making sure that the sprinklers do not get painted or obstructed are the most important items. It is also important to know the function of the main control valve and where the control valve is located. A.12.2 The building owner or manager should understand the sprinkler system operation and conduct periodic inspections and tests to make sure that the system is in good working condition. A recommended inspection and testing program includes the following: (1) Monthly inspection of all valves to ensure that they are open (2) Monthly inspection of tanks, if present, to confirm they are full (3) Monthly testing of pumps, if present, to make sure they operate properly and do not trip circuit breakers when starting (4) Testing of all waterflow devices, when provided, every 6 months including monitoring service (note that notification of the monitoring service is essential to make sure that the fire department is not called due to testing) (5) Ongoing visual inspection of all sprinklers to make sure they are not obstructed, damaged, corroded, covered with foreign materials, field painted, or showing signs of leakage, and that decorations are not attached to them (6) Annually, fully open the test connection downstream of any pressure-reducing or pressure-regulating valve, and make sure that the pressure gauge reads a reasonable value (7) Inspect systems by individuals knowledgeable and trained in such systems when there is a change in ownership A.12.3.2.1 It is recognized that the flow and pressure available to the replacement sprinkler might be less than its current flow and pressure requirement. A.12.3.3.2 Whenever painting or home improvements are made in the dwelling unit, special attention should be paid to ensure that sprinklers are not painted or obstructed either at the time of installation or during subsequent redecoration. This is as important for the cover plates of concealed sprinklers as it is to the sprinklers themselves. Special paint is used for cover plates and can only be applied by the manufacturer. Applying paint to cover plates outside of the factory can cause the sprinkler to malfunction and possibly not operate during a fire. When painting is occurring in the vicinity of sprinklers, the sprinklers should be protected by covering them with a bag, which should be removed immediately after painting is finished. For concealed-type sprinklers, the cover plates should be removed (most are designed to be unscrewed) and then the sprinklers should be protected underneath from paint and overspray with a bag. After the painting is finished, the bags should be removed from the sprinklers and the cover plates should be replaced. A.12.3.4 See Figure A.9.1.1(a) through Figure A.9.1.1(d) for possible methods used by the installer to insulate sprinkler piping in unheated areas. It is important that this insulation not be disturbed or removed. Disturbing or removing this insulation could result in sprinkler pipes being frozen during winter months that would not only block water flow to the sprinklers but could cause broken pipes and fittings.
