Main Firewater System Pressure
Main Firewater System Pressure
(OP)
I understand that the main firewater system pressure should be constant (jockey pumps keep the pressure in the system)so the opening of any point of consumption (hydrants, monitors ,etc) will cause the pressure to drop to a determined pressure set point and automatically start the firewater pumps. Is this set point code (NFPA) driven? Can anyone provide information on what drives the main firewater system set pressure?
Thanks in advance.
Thanks in advance.

There is an NFPA-20 Standard that addresses these pumps. Determination of the correct discharge pressure depends on your system configuration and function......

That would involve the hydraulic design characteristics (headloss) of the fire main from the fire pump to the point of application of fire water, as well as the hydraulic design characteristics of the fire monitors or sprinklers.
