    • • drop the basin on-scene in position for the engine to draft
    • • drop the low-level strainer and 4-1/2” double male at the scene
    • • install the chute in the proper direction

  209. It is imperative to request additional tankers and a refill engine as soon as the need for a tanker shuttle is recognized.
    Thing to consider
    Considering a 10 minute time frame per tanker (travel time of 5 minutes, refill time of 2-3 minutes, and a dump time of 2-3 minutes), one tanker can only maintain about 250 GPM. One additional tanker increases GPM to 500.

    • Governor?
    • valves are open, and there is water at your source.
    • Is your booster tank empty?
    • Is your intake valve fully open?
    • Is there a kink in your supply line?
    • Is the hydrant fully open?
  220. This can occur when an attempt is made to pump more water than is available.
    It can occur when drafting, from the booster tank, when operating from a hydrant, or when relay pumping.
    When residual pressure approaches 0PSI and the impeller speed remains constant, the pressure at the eye of the impeller decreases. As this occurs, water temperature will increase at the impeller eye and create water vapor. The vapor condenses as it passes through the impeller vanes.
    This results in the characteristic “pebbles in the pump” sound.
    “running away” from the water.
    If this condition is allowed to continue, serious damage can occur.
    The earliest indication of ______ is fluctuating PDP.
  221. Water flowing through hose has a maximum velocity, called _____ _____. At this point any effort to increase velocity (by increasing PDP) creates turbulence in the stream and the result is a loss of stream reach and integrity. can lead to pump cavitation and reduced volume from the nozzle

    critical velocity
  223. you have reached critical velocity. At this point the engineer should:
    • • reduce throttle RPM’s
    • • reduce the nozzle flow - change the smooth bore tip, or adjust the fog nozzle flow to the next lower setting
    • • increase hose size - the same volume that resulted in critical velocity in 1-3/4” hose will flow better through 2-1/2” hose.
  224. Unable to Prime
    almost always caused by?

    most common causes?
    • An inability to prime is almost always caused by air leaks.
    • The most common causes are a partially open valve or an open bleeder.
  225. unable to draft after taking care of potential air leaks, attempt to displace air
    with booster tank water. At the same time you engage the primer, open the TANK TO PUMP valve for a few seconds
