REMEDY
Fill the pump with water
Check the recommended and used pans
and components of the pump, e.g. joint
of the suction nose, joint of the pressure
hose, clamping ring, suction hose, etc.,
including screw sealing strip made from
Teflon or hemp cord. The pump can
work only when well sealed
Clean the non-return of the sucking inlet
and the filter screen
When the pump starts sucking, open the
water outlet (e.g. the tap. sprinkling
nozzle etc.)
Fill the whole suction hose with water, or
recheck it at least 7 minutes after the
pump starts
Reduce the suction head
Check the water level of the well or the
water pool. If possible, increase the
length of the suction hose.
Check the power supply
Pull out the power plug, remove the
ventilator hood with a screwdriver, then
reinstall it again by slightly rotating the
vane and check to see if it rotates freely
Pull out the power plug, move the shaft
with the screwdriver through the
ventilator hood. If the shaft is blocked,
send it to a service center for inspection
Check the suction head
Clean the filter screen
Immerse the non-return in deep water
Wash the shell of the pump, the suction
hose and the outlet pressure hose with
pressurized water
Wash the shell of the pump with
pressured water
Check to see if a valve is installed on the
suction hose
