Problem Possible Cause Remedy
Pump runs, but the suction
action doesn’t take place
Pump sucks in air at a joint. v Seal connections on suction side so
are airtight.
Leaky or damaged suction
hose.
v Check suction line for damage and
seal so is airtight.
The pump was not filled with
the liquid to be pumped.
v Fill the pump (see 3. OPERATION).
The liquid escapes over the
hose which is connected to
the delivery side during the suction
action.
1. Fill the pump again
(see 3. OPERATION).
2. When starting operation hold the
pressure hose approx. 1m vertically
above the pump, until the suction
action has taken place.
Absolutely vacuum-resistant connection is achieved by using GARDENA
Suction Hoses (see point 7. ACCESSORIES).
Leaky screw fitting
