So true. And I love when the specifying engineers don't research the local amendments.
One large jurisdiction here does not allow a reduction in site fire flow for 13R systems, and only a 50% reduction for 13 systems. I'm the bad guy when we have to tell the developer that they have potential problems because of local requirements. It's getting better but still happens.
