Spot the apparatus correctly
Use someone on the ground to help. Set up so that you can get a nice wide horseshoe
bend in the hose. Someone who can see the hydrant should guide the driver and another
person should watch the rear of the apparatus for safety.
Remove the 6" hard suction
Lay the hose out in a position close to where it will be utilized, female ends toward
the apparatus. Also get out needed fittings and tools such as a LDH spanner,
mallet, hydrant wrench and LDH double female adapter.
Remove the front soft suction
Uncouple the soft suction and remove the 6" to 4½" reducer.
Hook one length to the hydrant
Connect the LDH double female to the hydrant. Connect the 6" to 4½" reducer
to the end of the hard suction hose. Couple the hose to the hydrant. This is
done most efficiently using three personnel, two to level the hose while the
third spins and tightens the coupling.
Hook the other length to the engine
Connect the second length to the front suction connection. Utilizing the full
crew of three to level the hose makes the hookup go much faster and easier.
Hook the lengths together
With one person on each hose and a third person making the connection, level
and connect the hoses and tighten with a mallet. (The reason for this order
of connecting is that it is easier to make the final connection in a more
Prepare to pump
Open the hydrant fully. Purge the air from the line using the front suction drain.
Once water is showing close the drain, make sure the tank to pump line is closed,
expel remaining air with the primer and establish a prime using standard drafting
The engine should have no problem pumping at least 1000 GPM from his hookup.
