I have a situation where 175 sprinklers have to be replaced in an apartment building where the original design/installation utilized low flow residential sprinklers (2.8K) due to damage or painting. It is my understanding that these sprinklers are not available anymore and I need to replace them with a 3K residential sprinkler. They will have the same temp rating and RTI so I don’t think that will be an issue. Other than the need to prove the 3K sprinkler will work hydraulically does anyone see other code issues I am missing that might make having different sprinklers from different manufacturers in the same dwelling compartments a compliance issue?
