No water supply
at all (continued).
The mains water valve
may be closed.
* Only applicable if
application is using
a digital water switch.
Check that the mains water
isolation valve is open.
Incoming mains water
pressure may be
greater than 1000kPa.
* Only applicable if
application is using
a digital water switch.
Fit a pressure reduction valve to
reduce incoming mains pressure.
The Green LED light
on the pressure
controller is not on.
* Only applicable if
application is using
a pressure controller.
Power to the pressure
controller may not
have been turned on.
Check the power supply.
The pressure
controller may not
have restarted.
The pressure controller is still in ‘lock
out’ mode, meaning it has detected a
loss of prime (tank empty). If the tank has
been refilled with rainwater, the pressure
control can be manually reset by pressing
the “Restart” button on the device.
Pump “Error” or
RED LED signal
appears on the
Pressure Controller.
* Only applicable if
application is using
a pressure controller.
The pump may
have failed to prime
(i.e. the tank is
empty, no water
is being detected).
The pressure controller is protecting
the pump against loss of prime.
1. Simply press the “Restart” button.
2. If the system fails again, the unit is
detecting that there is air in the suction
pipe and has shut down to protect
the pump from long term damage.
3. Check there is water in the tank.
4. 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.
5. Activate all appliances/outlets
sequentially from the nearest to the
furthest outlet. Repeat if necessary.
6. If problem persists, please contact the Reece
branch where the pump was purchased from.
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.
