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
using a screw coupling, but it is not recommended for
use in lines smaller than 8" (203mm) in diameter. The
long length of the hose connectors and coupling together
can get caught in bends in the line.
PART NUMBER ADAPTER SIZE (FPT)
8.705-364.0 1/4" x 1/4"
8.705-366.0 3/8" x 3/8"
8.705-369.0 1/2" x 1/2"
8.705-371.0 3/4" x 3/4"
Coupling two different size hoses can be done through
the spray wand trigger or foot pedal.
It is not advisable to have two different hose sizes
coupled in a drain line. There is a tremendous loss of
pressure when combined, aside from the difficulty of
getting around bends.
The 3/8" (9.925 mm) and 1/4" (6.35 mm) hoses may be
attached to the fitting in the core of the hose reel using
the swivel at one end of the hose. The 3/8" hose may
also be attached directly to the accessory outlet by us-
ing a twist connect. The 1/4" and 1/8" (3.175mm) hoses
may be connected directly to the accessory outlet if an
adapter fitting is used between the hose and quick con-
nect. Adapters may be ordered separately.
Often, the 1/8" hose is used in conjunction with the
spray wand trigger to give the operator finger tip control.
Remove the spray wand from the trigger and attach the
1/8" hose using the appropriate adapter.
A SFP valve is available that can be used as a safety
shut-off valve for all hose sizes. See foot pedal section
for installation and operating instructions.
Nozzles
A number of types of nozzles are available for drain
cleaning. Each has a different spray pattern. Some
nozzles may have a hole in the front to cut though the
stoppage. All will have holes in the back to drive the
hose down the line and clean the walls of the pipe. A
combination of nozzles may be required to clear a line.
Always turn off the machine and shut off valve before
changing nozzles.
Make sure the nozzle you are using matches the pump
size. A 3000 psi
(207 bar) pump requires a different
nozzle orifice than a 1500 psi (104 bar) pump. Mismatch-
ing nozzles with pump size will either cause too little
pressure which may not clear the drain, or too much
pressure which may damage the machine.
Check nozzles before and after each use for clogged
holes which can cause pressure to increase to danger-
ously high levels and damage the pump. A clogged hole
can be cleared by simply using a nozzle cleaning tool.
Use the nozzle selection guide to determine what nozzle
you will need for various applications.

Rotary Nozzles
Rotary nozzles are useful as a finishing tool. After the line
has been cleared, you may switch to the rotary nozzle to
more thoroughly clean the walls of the pipe. Use these
nozzles only in a predominantly straight run since they
are longer than regular nozzles and may get caught in
tight bends. Please note that the rotating nozzles will
operate at a lower pressure than the standard nozzle.
Rotary nozzles can be adapted using the nozzle adapt-
ers and bushings below:
