The pump stops
after running for
a short period of
time (continued).
The suction pipe
internal diameter
may be too small. A suction pipe size that is too small will cause
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.
Debris may be caught
in the pump impeller. Check for solid objects that may
be blocking the impellers.
1. Disassemble pipework and pump housing.
2. Clean impellers.
It is recommended to call a pump
technician or licensed professional.
The in-line strainer
on the suction line
may be blocked. Check for blockages in the in-line strainer:
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 pump may have
been incorrectly sized
for the application. Contact the Reece store where the
product was purchased from.
The mesh filter in the
digital water switching
unit may be blocked.
* Only applicable if
application is using
a digital water switch.
If a digital water switching unit is installed:
1. Switch off power to the unit.
2. Isolate the water lines and remove
the pump barrel union.
3. Inspect/clean/replace the
switching unit mesh filter.
