A pressure controller
or mains switch over
device has not been
installed on the pump.
Without a pressure controller or mains water
switch-over device, the pump will continue
to operate until the power is switched off.
The pump may not
have been primed
correctly and air
may be trapped in
the pipework.
The pump may have not been primed
correctly and 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.
Pump is turning
on then off in
short durations.
The pump may
not be providing
sufficient pressure.
The pump may not have been primed
correctly and there could be potential
of air still in the suction pipeline.
Check the pressure gauge on the side
of the pressure controller to determine
if that model pump is operating correctly
when referencing its pump curve.
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.
