TROUBLESHOOTING
Pump is turning
on then off in
short durations
(continued).
The pump may not be
providing sufficient
pressure (continued).
There may be debris caught within the first
impeller not allowing pressure to be created:
1. Disassemble pipework and pump housing.
2. Clean impellers.
It is recommended to call a pump
technician or licensed professional.
The pump may not be suitable for the
water application. Check to confirm
pump suitability on page 10.
There may be
presence of leaks
which are higher
than the minimum
flow of 0.6 l/min.
If the pump is turning on, then off in short
durations there may be a leak in the pipework.
1. Close the isolating valve on the
discharge line of the pressure controller
to see if the issue continues.
2. If it does not, check all taps, pipes, irrigation
solenoid valves & toilet cisterns for leaks.
3. If it does continue, then check pressure
control and suction pipe for debris.
4. If found, repair or replace pipework.
The electronic card in
the pressure controller
may be broken.
* Only applicable if
application is using a
pressure controller.
If a pressure controller has been installed,
the electronic card in the controller may
need to be removed and replaced with
a new card, or a new unit entirely.
This should only be done by
a qualified electrician.
The pump vibrates
and operates noisily.
The pump and
pipework may not
be firmly anchored.
Fix the pump and pipes securely.
There may be
cavitation in the pump
(demand for water
is higher than it
can pump).
* Cavitation can be
identified by the noise
of the pump. You
will hear a bubbling,
crackling sounds like
marbles rattling inside
the pump casing.
The length of the suction pipe may be too long,
or the internal diameter may be too small:
1. Reduce either the suction
height or distance.
2. Increase the suction pipe internal diameter
to same size as the pump inlet or larger.
The pump may have
been incorrectly sized
for the application.
