5. If it does continue, then check pressure
control and suction pipe for debris.
6. If found, repair or replace suction line.
The suction pipe diameter may be too
small and causing high pressure loss
or cavitation. Increase the pipe size to
an internal diameter that is the same
size as the suction inlet, or larger.
Note: This means for a 25mm inlet pump
a 32mm PN12.5 Poly Pipe must be used.
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 9.
The in-line strainer or filter on the suction
line pipework may be blocked.
1. Close the isolating valve on the suction line.
2. Remove/clean in-line strainer
or replace if necessary.
3. Once in-line strainer has been
cleaned, open isolating valve on
suction line and retry for pressure.
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.
