Flow Test For Fire Pump Youtube The electric pump needs to run for a minimum of 10 minutes. the diesel pump needs to run for a minimum of 30 minutes. a pressure difference greater than 95% of the rated pressure needs to be investigated and corrected. regular no flow testing is a vital part of ensuring fire pumps can be relied upon. essentially, no flow tests ensure fire pumps.
