Reverse Hose Lays and Drafting

PUMP OPERATIONS ON REVERSE HOSE LAYS          

Lesson Plan

The driver plays a critical role in delivering water quickly on a reverse hose lay. They must “spot” the engine correctly at the hydrant to effectively make their suction connection. The hose supplying the fire attack must be disconnected from the hose bed and attached to a pump discharge in a timely manner.

Key operational points for pump OPS on a Reverse Hose Lay

  1. Try and lay hose in a manner that will not block the street if possible
  2. Spot hydrant to use 4 ½” soft suction
  3. Connect 4” line to discharge on Officer’s side of engine
  4. Make radio contact with receiving company to ensure correct pressure

DRAFTING                  

Lesson Plan

Operating from a draft is the most demanding type of pump operation, both from the standpoint of the apparatus and operator. It demands a careful monitoring of the gauges associated with the engine as well as those associated with the pump.

Key operational points for Pumping from a Draft

  1. Ensure valves, drains, caps and plugs are closed and tight to prevent air leaks
  2. Allow 2 feet of clearance around pump strainer in all directions
  3. Open discharges slowly to prevent loss of prime
  4. Always maintain flow of water using Tank Fill valve or dump line to prevent loss of prime
  5. Observe vacuum gauge, increasing vacuum could indicate clogged intake strainer
