We need to replace 3 painted heads in an existing storage room that currently has 14.5 k heads. Going to the closest Equivalent head changes the K factor to 14.0 and it makes enough of a difference that the calks no longer work……
Even if we replace all of the heads in that area with 14.0's it will not work. Does anyone happen to have these laying around? Question - if we can't find them, what should we do? The calcs do not work due to a combination of a slightly degraded water supply and being incorrectly calculated by the original installing contractor - we have the original drawings and they used a .15 density throughout the building instead of the required .20. (yes- even when originally installed). The difference is only a few pounds, but it goes from slightly positive to negative. The AHJ has closed his ears and eyes and said "get the painted heads replaced". Thanks for your help.
