Tapping the delivery line with a hammer handle
During the cleaning process, tap the delivery line shortly be-
fore the cleaning port with a piece of hardwood (hammer
handle).
Notes
If there is concrete in the delivery line, tapping produces deep, thud-
ding sounds. As soon as the concrete and wash-out sponge have
passed the tapping point, the tapping produces high, clear sounds.
Tap the delivery line only with a hammer handle because otherwise
the pipe could be damaged.
Switch off the pump once the wash-out sponge has passed the
tapping point.
