I am running into a lot of old systems that do not have hydraulic placard and some of them are old pipe scheduled system. Has anyone ran into an old pipe schedule system were the fire marshal is requesting hydraulic placards and if so has anyone found a way to satisfy the requirements without surveying the entire system and running new calculations?
