7.6.1 Washing the piping
The pipes and hoses can be washed in three different ways:
1) by flushing with water under pressure
2) by flushing with compressed air
3) by reverse pumping (vertical piping only)
Note that:
- Flushing with water or compressed air lets you use all the concrete produced since it is expelled onto the place of application.
- With reverse pumping the slurry inside the piping is brought back to the hopper. Bear in mind that the hopper's capacity will
let you recover about 200 litres of slurry.
- FLUSHING WITH WATER
- Soak a pipe sponge (FIG. 39-REF. 1) and put it inside the pipe.
- Connect the pipe to the machine and open the gate valve if present.
- Connect the basket (FIG. 39-REF. 2) designed to catch the sponge to the end of the hose using a Victaulic coupling complete
with rubber gasket.
- Fill the hopper with water and start pumping.

The sponge will be violently expelled from the hose. Make sure the hose is pointing in a direction where
there is no risk of harming anyone or damaging anything. If the piping is encrusted the sponge will not be
expelled. In this case, reverse the direction of pumping to reduce the pressure inside the piping and stop
the machine.
In case the pipes are found to be clogged when flushing, follow the instructions in paragraph 7.7.
