side so are airtight.
Leaky or damaged suction
hose.
v Check suction line for damage
and seal so is airtight.

hose which is connected to
the delivery side during the
suction action.

side is closed or remaining water
is in the pressure hose.
v Open shut-off valves
(e. g. nozzle) in the delivery
line, empty the delivery hose
or disconnect it from the
pump during priming.
