pressures. Make sure the nozzle orifices are clear and
open.
See Jetter Nozzle Selection Chart.
If using the RR3000 nozzle for drains larger than 6"
and up to 9"/ 229 mm, the extension must be used.
For drains 6"/ 152 mm and smaller, no extension is
needed. If needed, firmly hand tighten the extension
to the RR3000 – do not over tighten. Using the
RR3000 nozzle in a line larger than 6" and up to 9"
without an extension, or in lines larger than 9" may
allow the nozzle to change direction in the drain, exit
at the user and cause serious injury
(Figure 12)
.
9. Firmly hand tighten the nozzle to the end of the hose
– do not over tighten. Over tightening the nozzle can
damage the nozzle and cause poor performance.
10. Insert the hose with nozzle attached into the drain and
open the inlet supply valve. Confirm that water flows
freely through the nozzle and close the inlet supply
valve.

Features four (4) reverse jet thrusts for maximum propulsion to jet long distances. Use this
nozzle for most applications.
Uses three jet thrusters in reverse plus one jet pointed forward to penetrate solid grease or sludge
blockages. The forward jet blasts a small hole in the blockage for the nozzle to follow. It is also
very effective when jetting ice blockages.
Use the drop head to help negotiate difficult bends. This nozzle has four (4) reverse jet thrusts.
Use the spinning nozzle to help clean grease and similar blockage from drain.
Use to clear roots and other type of blockages.
NOTE! Use extension to stabilize the RR3000 when cleaning 8" diameter drains.
