Flow Test of an Electric Fire Pump

Performing the required NFPA 20 and 25 annual flow test of a small 500gpm horizontal split case centrifugal fire pump with an electric motor driver. There are several required items that are not covered in this video. This video is just to give you an idea of what is done during a fire pump flow test. Even after I cut some steps out of the video, it's still long. I added a timeline to help you find each step.
