What does NFPA 13d Require for Maintenance on Sprinklers Systems in the Home?
Residential sprinkler systems are now showing up in more homes due to local ordinances and the requirements set forth in NFPA and the ICC. It seems that the questions on maintenance of the system becomes a key part of the discussion when looking at the system. NFPA 13d maintenance requirements are different then a NFPA 13 sprinkler maintenance, and there are many resources available to help the inspector as well as the home owner.
NFPA 13d refers the user to section 4.2 Maintenance.
4.2.1 The installer shall provide to the owner/occupant instructions on inspecting, testing, and maintaining the system.
4.2.2 Operated or damaged sprinklers shall be replaced with sprinklers having the same performance characteristics as the original equipment.
4.2.3 Any sprinklers that have been painted outside of the factory shall be replaced with a new listed sprinkler.
4.2.4* Antifreeze Systems. Before freezing weather each year, the following procedure shall be performed:
- Solution in the entire antifreeze system emptied into convenient containers
- Solution brought to the proper specific gravity by adding concentrated liquid as needed, or a new solution be prepared, in accordance with 8.3.3
- System refilled with the new or remixed solution
Lets take a look at a common example based on the code sections listed above. Most new construction utilizes a mulit-purpose system and are considered “wet” systems.
The home owner would need to ensure:
- Any open or defective sprinklers (painted sprinkler) are replaced with the sprinklers based on the design. This typically would be completed by a sprinkler contractor.
- Ensure the water supply to the system is on.
- Keep a record of the monthly inspection
- Check your smoke alarm to!
