Does anyone know what year gridded Dry systems were prohibited?
Does anyone know what year gridded Dry systems were prohibited?
(OP)
We have a project that we are doing that has a gridded dry sprinkler system? I know that these are now prohibited and have been for a while. The system is not that old however. We are curious along w/ the local AHJ what year gridded dry systems became prohibited per NFPA 13. Anyone know?

Remember that many of the NFPA and International code provisions are written specifically in response to loss history. Tell the code official not worry about the when - rather, worry about the why.

50 static, 35 residual @ 600 gpm and you would have a problem but 152 static, 150 residual @ 2,100 gallons and gridded systems would work just fine. On one of my projects I actually have this fine water supply. :)
I wish they would allow dry grids back (I know, no way of this ever happening) with the strict 60 second rule requirement regardless of system size.
