The Digital Water
Switching Unit has
gone into “loss of
prime” (no water is
being delivered to
pump) (continued).
* Only applicable if
application is using a
digital water switch.
Pump may not
have been primed
(continued). The pump may have not been primed 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.
No water is delivered
from mains.
* Only applicable if
application is using a
water switch device.
There may be no
mains water available. Check the isolation valve on the water meter.
There may be
debris caught in
the mechanical
switching valve.
* Only applicable
if application is
using a mechanical
water switch.
If a mechanical switching valve is
installed, open the bleed plug.
Refer to page 16 to identify bleed plug.
