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.
Contact the Reece store where the
product was purchased from.
No water is
delivered from
the pump, or the
pump performance
has decreased.
The rainwater tank
may be empty.
1. Check the tank level.
2. If empty/low, wait for the tank to refill.
There may be
no power supply
to the pump.
1. Ensure that the power is turned on and
check the connection to the power point.
2. Fuse may have blown. Contact a
pump technician or contact your local
Reece branch to replace fuse.
3. Electrical power line may
have been damaged.
The suction or
discharge line
may be closed.
Check the isolation valve and ensure that it
is open at the water source (tank outlet).
There may be bad
signal from the float
switch.
*Applicable
to VFB-DSU only.
Check the installation and
operation of the float switch.
Refer to the full Vada Flow Boss Digital
Water Switching Unit manual for instructions
on how to install the float switch.
The pump may
not have been
primed correctly.
There is potential of air still in the suction pipeline.
1. Check the pressure gauge on the side
of the pressure control to determine if
that model pump is operating correctly
when referencing its pump curve.
2. Bleed air from system while the suction
line is connected to the pump.
a) Above ground tank: Remove
priming plug on pump casing. Allow
water to flow through via gravity
until all air has been expelled.
b) Below ground tank: Ensure foot
valve is installed, fill up suction line
and casing from discharge point.
3. Activate all appliances/outlets
sequentially from the nearest to the
furthest outlet. Repeat if necessary.
4. If problem persists, please contact
the Reece branch where the
pump was purchased from.
Refer to page 16 for more information
on priming the pump.
