Jockey pump for vertical turbine fire pump

[John_187]

Hello

There is a vertical turbine fire pump and there are some details I don't know about for how to install a jockey pump with this setup. The pump rep gave me a vague selection of a grade mounted jockey pump. The water level is 17 feet below grade in the pit below.

Is there some kind of automated primer valve for the suction line of the jockey pump to keep it full? Air purge valve? It should require a check valve too.

Should the suction line of the jockey pump stub directly into the sump pit for the vertical turbine fire pump?

Thanks for any help

Sorry for the late response. I would use a submersible well pump on a drop pipe in the wetwell next to the fire pump. Drop pipe should leave it just above the suction bell of the fire pump so as not to cause interference with suction.
