No water is
delivered from
the pump, or the
pump performance
has decreased
(continued).
The in-line strainer
on the suction line
may be blocked. If you do not regularly clean the filter,
it will clog up and cause the pump to fail.
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.
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.
The pump may
be sucking air. There may be a leak in the suction line,
or the pump was not primed correctly.
1. Ensure that the joints on
suction line are airtight.
2. If joints are airtight, reprime the pump
by bleeding 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.
The liquid column
may be above the
check valve on the
discharge line. The weight of water can force the check valve
on the discharge line to close. This prevents
air being expelled from casing and suction line,
affecting the pump’s self-priming performance.
Ensure water is completely drained
above the level of the check valve.
