Certain fire calls that we respond to will have nothing showing when arriving on scene. This is when an investigation will take place to determine the exact cause of the call or to rule out any problem. While waiting for the investigation to unfold, the apparatus operator can place the pump in gear to reduce the time needed if a charged hose line is required.
With the pump in gear, the operator can open the tank to pump valve as well as the tank fill valve to recirculate the water inside the pump. This will remove the possibility of overheating the pump and causing complete pump failure. By doing this ahead of time, the pump operator becomes more effective and gives them the upper hand with deploying a hand line quicker and easier. This is also good practice for the pump operators to refine their skills. As easy as it may be, putting the pump in gear can be forgotten when there is a real fire showing on arrival.

Ron BecknellSunday, October 21, 2012 6:47:42 PMMy department stresses the technique mentioned here of recirculating the water through the tank to keep the pump cool. As for engaging the pump while in investigating mode: this could a benefit if the structure is small and the apparatus is located in the correct place. However if the building is large like a grocery store or warehouse there may be a benefit to the truck being ready to relocate to the closest point of entry to the fire.

Kurtis CookSunday, October 21, 2012 8:08:32 PMI think the operator should pull a handline off the truck and drop the nozzle down in the tank then charge it. That gives you a complete circulation of the pump and helps flush out the hose. Ok now get out there and try it.
