largest possible hose size in order to have as much pressure
as possible at the end of the hose.
Hoses of the same diameter may be coupled together
but it is not recommended for use in lines smaller than 8”
diameter. The solid metal of the combined hose connectors
and coupling, can get caught in bends in the line.
Pulse-abler
The stem and handle extending from one cylinder of
the water pump enables pulsation of the water stream
through the hose and nozzle.
By turning the pulse-abler handle clockwise (or right),
you temporarily disable one valve of the pump. This
creates pulsation or vibration in the hose, allowing the
hose to “wiggle” through tight bends quickly and easily.
Turn the pulse-abler control left to stop pulsation.
u
Use pulsation only as needed to arrive at an
obstruction or to retrieve a stuck hose.

Pressure Regulator/Unloader
The regulator/unloader both regulates the pressure and
relieves pressure on the pump while in bypass.
The Regulator knob is located at the pump. It allows you to
adjust pressure during operation.
Set the engine throttle
to a constant motor speed before adjusting pressure
regulator,
lower rpm equals lower pressure at the pump,
while high rpm delivers higher pressure.
The Unloader prevents pressure overload in the event that
the nozzle is plugged or the ball valve is shut off. When
in the by-pass mode, the pump will continue to run.
u
Avoid running in by-pass mode for more than
2 minutes if the by-pass is not returning to the
float tank. It can damage the pump.
Pressure Gauge
The gauge reflects pressure from the pump only, not
pressure at the end of the hose. It is important to select the
