Fire pumps
Fire pumps
(OP)
I got a call about a fire pump that was running. When I got there, I checked on/off pressures of the jockey pump and the on pressure of the fire pump. All the settings were good. There were no downstream valves that had been opened. Could it be a clogged sensing line issue on the fire pump or maybe the pressure switch in the fire pump controller going out?

Was the pump running when you arrived? Someone nay have opened and closed a hydrant.

There have been incidents where fluctuations in the water pressure caused accidental starting of a fire pump.
