Tap Water Sources in Remote Locations
Rural fire companies need creative solutions to utilize water sources that are
not accessible using typical drafting techniques. The Lo-Level Power Jet Siphon
allows fire companies to tap into water supplies like ponds, streams, and
swimming pools up to 250' away and can generate flows up to 670 gpm.
Low-Level Jet Siphon Setup
Low-Level Jet Siphon setup is quick and simple. Just place the unit in a
convenient water source remote from the fire truck with a 1.5" (38mm) discharge
and a 4”, 5" or 6" supply hose connected to the unit. Threaded or storz.
Once the Low-Level Jet Siphon has been set up it can be quickly placed into
service. The steamer suction valve is left closed and its air bleeder is opened.
The 1.5" (38mm) line is charged to approximately 175 psig. The force of the flow
combined with Low-Level Jet Siphon creates a suction which draws water from the
standing water supply. As this happens, the return line is charged back to the
fire truck. Once the air is bled from the supply line the bleeder is closed and
the steamer valve is opened. At this point the water supply has been
established. 100 GPM is re-circulated through the truck to maintain a continuous
flow and 670 GPM is available to supply tanker trucks or fill portable tanks.
Useable fire flow will vary based on elevation and hose friction loss and size
of unit ordered.
