1. Pump will not start – Control valve is under
tightened. Refer to control valve adjustment
for adjustment instructions.
2. Pump will not shut o󰀨 – Control valve is over
tightened. Refer to control valve adjustment
for adjustment instructions.
WATER PRESSURE:
40 PSI minimum with valve open.
80 PSI maximum with valve open.
100 PSI maximum with valve closed.
EFFICIENCY:
The pumping capacity increases with household
water pressure and ow.
At an eight-foot static head and a supply pressure
of 40 PSI at water supply inlet with water owing,
it takes one (1) gallon of supply water to remove
one and a half gallons from the sump. As the
supply pressure increases with the static head
constant, less supply water is required.
TROUBLESHOOTING GUIDE
CONDITION POSSIBLE CAUSE REMEDY
A
PUMP WILL NOT
START OR RUN
Inadequate incoming
water pressure
Check incoming water line for closed valve, low
water pressure or clogged lter/strainer.
Excessive incoming
water pressure
Install regulator and reduce pressure below
100 PSI with valve closed.
Debris around Intake Clear debris from pit and foot valve strainer.
Float hung up on pit or
primary pump
Move pumps so that the oats move freely and
do not contact pit, piping or each other.
Control valve is under-
tightened
Refer to section on control valve adjustment.
B
PUMP STARTS
TOO SOON
Float valve is positioned
too low
Refer to section on oat valve installation.
C
PUMP WILL NOT
SHUT OFF
Float is obstructed Inspect oat operation and correct problem.
Internal valve diaphragm
vent hole is plugged with
debris
Turn o󰀨 water supply to pump and back on
repeatedly to dislodge debris. If this process
does not remedy the problem, service pump to
clear debris or replace valve assembly.
Control valve is over-
tightened
Refer to section on control valve adjustment.
D
PUMP OPERATES
BUT DELIVERS
LITTLE OR NO
WATER
Debris around intake Clear debris from pit and foot valve strainer.
Inadequate incoming
water pressure
Check incoming water line for closed valve or
low water pressure.
Blockage in discharge
pipe
Remove pipe and ush out debris.
Foot valve above water
level
Adjust Float - Refer to section on oat valve
installation.
Vertical lift too high Change discharge piping or contact technical
service.
