Working on a small project that has a fire pump. Instead of conducting a new flow test at the hydrant that is feed from the fire pump it was suggested to use the annual fire pump test. I’m trying to remember how to do that since it’s been years. Can someone help me out?
I have a light hazard building with Dry wall, 12" bar joists, with 6" of batt insulation on the dry wall and then a wood floor for above. So 6" of dead space above the insulation to the underside of the floor. Would this be considered Combustible Concealed space?
Thanks
