Possible cause Solution
Pump or pipework dirty or
partly blocked.  Disassemble, clean and
check the pump and
pipework.


Replace damaged and/or
worn parts.
Riser is damaged.
 Repair or replace
pipework.
Problem: Frequent stopping and starting of the pump.
Possible cause Solution
The difference in the pressure
switch between switching on
and off is too small.  Increase the difference
(switch-off pressure may
not exceed the operating
pressure of the vessel;
switch-on pressure must
be high enough to
guarantee sufficient water
supply).
Electrodes in the water level
control or water level switch in
the container are not installed
correctly.  Set the intervals for the
electrodes so that a
reasonable amount of
time is left between
switching the pump on
and off (if there is no
automatic set up, reduce
the pump performance via
the throttle).
Non-return valve is leaky.  Repair or replace non-
return valve.
Too low an air volume in the
pressure vessel/diaphragm
pressure vessel.  Pump air in (galvanised
vessel: until the air
pressure is approx. 2/3 of
the whole pressure vessel
