OPERATING TIPS
We would like to provide you with some tried and
tested tips and techniques to make your jetting
experience an easier and more enjoyable one.
• Be sure to always use the safety plate as it will protect
your jetting hose against damage from both sharp
edges and rough surfaces present at the entrance
to the drain. Remember, more damage is done to a
hose upon the entering and exiting of the drain than
anywhere else. Additionally, the safety plate prevents
the jetting nozzle from accidentally existing the drain
whilst under pressure.
• Begin your jetting with a long nozzle, such as the
Predator, or for smaller drains, such as the
Compressor.
• To combat extremely tight bends, remove the quick
coupler from the hose, the cowling from the nozzle,
and connect the head directly to the hose.
• Twist your jet hose in order to effectively manoeuvre
it around tight bends and traps
• Once you have broken through the blockage, change
to the Root Ranger in order to clear the tree roots
from the sides of the drain. Additionally, when using
the Root Ranger Turbine, the hose must be twisted in
order to thoroughly clear the root choke from all
sides of the pipe.
• To prevent the Root Ranger Turbine from entering
side channels, simply push through the junction
as quickly as possible, without twisting it. Doing so
will maintain the turbine on a straight path.
• If your hose happens to become jammed, which is a
fairly common occurrence, pull the hose hard and
then let it go quickly so that it may snap back and
loosen itself. Additionally, turn off the jet, pull the
hose, and then turn the jet back on once more.
• When accessing a square junction down a shaft, a
section of 50mm of pipe with an elbow on the end
may help direct your nozzle up and into the desired
location. Alternatively, you may run your hose
through a section of flexible pipe, such as a 50mm ag
drain, in order to assist in the directing and
protecting of the jetting hose.
While the Root Ranger is considered top of the line,
it will become stuck on a regular basis. In an effort to
mitigate this:
• Attempt running the Root Ranger straight towards
the blockage, without twisting the hose.
• Delay the twisting of the hose to when you are
actually cutting the roots or retrieving the hose from
the blockage. Such a practice will stop it moving up
any branch drains, toilet pans and PVC capped
inspection openings!
• When managing drain larger than 6’’, be sure to add
an extension to the Root Ranger in order to prevent
it from becoming wedged.
