           window opposite cone

       c. Allows fill hose to be located at rear of vehicle

       d. Reduces need to move hoselines back and forth when vehicles arrive

  5. If tankers being filled have two 2½-inch direct tank fill connections, two 3-inch hoselines laid to

       approximate location of rear of tanker when parked for filling

        a. Each hoseline should have gate valve installed between last section and second to last section

           of hose

        b. Valves used to open lines once connected to tanker for filling

  6. Jurisdictions prefer to equip inlets on direct tank fill connections with Storz couplings

       a. Couplings speed connection of hose to apparatus

       b. If apparatus equipped with Storz connections, may be necessary to install Storz adapters on

          end of hoses used to fill tankers

       c. Main point that apparatus operating in shuttle should use same type of connection so

          adjustments not need to be made each time different apparatus filled

  7. If the tankers being filled have LDH direct tank intakes, only necessary to lay one LDH from fill site

      pumper to fill location

        a. If large in-line gate valve not available for LDH, may be possible to place LDH manifold

            between last two sections of hose to act as gate valve

        b. If no gate valve or manifold available, best to open and close LDH fill lines at pump panel of fill

           site pumper

  8. If some tankers to be filled have 2½-inch intakes and others have LDH intakes, necessary to lay

      out hose easy to connect to either

        a. Best method for accomplishing to lay one LDH to area near fill site

        b. Connect manifold to LDH line

        c. One LDH and two 3-inch connected from manifold

        d. Gate valves on manifold then used to operate whichever lines being used

         e. Manifold supervised by radio-equipped firefighter familiar with water movement and

            preferably by pump operator

D. Top Fill Methods

  1. Previous method for laying out fill site considered to be efficient under most circumstances

       a. In some jurisdictions, more common to fill tanker through fill or vent opening on top of

           apparatus

       b. Accomplished using either fixed or portable filling equipment

       c. If fixed equipment used, fill site limited to location

  2. One method of top filling uses permanent or portable overhead pipes used at static water supply

      source

      a. Portable fill pipes made of PVC or other lightweight material

      b. Fixed overhead pipes constructed of any suitable material

      c. Devices operated by placing one end of fill pipe in static source

      d. Pumper discharges into in-line jet within fill pipe

      e. Creates high flow rate through fill pipe

      f. In-line jets pumped at 150 psi and provide 700 to 800 gpm through 4-inch pipe

      g. Larger diameter piping provides additional flow

      h. Devices advantageous when tankers have no other way of being filled other than through top

          opening

      i. More efficient use of pumper supplying in-line jet to simply draft from site and pump directly into

         tankers

  3. Another method of overhead pipes uses permanent or portable manifolds

      a. Permanent pipes located adjacent to water source and fed by fill site pumper

      b. Water sources may be hydrants or static supply source

      c. With devices, fill site pumper connects between water supply and fill pipe to provide overhead

          water when tanker positioned beneath fill opening

      d. If water supply source reliable one, high fill rates accomplished through devices

      e. May take some jockeying to get tank opening positioned directly beneath fill spout
