Greetings, I am quoting sprinkler installation and fire pump for a new building that is going to be built here in my city. but when checking the designs and the blueprints, i come across a detail that specifies that the fire pump will only supply for the upper half of the building and the rest of the building is going to receive the water supply from the rooftop tank by the weight of the water column.
pump room is at the rooftop beneath the water tank.
but shouldn't the whole building be supplied by the fire pump? or is it possible to separate supply to the system in such way?
