Performance Characteristics
CONDITION POSSIBLE CAUSE REMEDY
A PUMP WILL NOT START
OR RUN
Inadequate incoming water pres-
sure.
Check incoming water line for closed valve, low water
pressure or clogged filter/strainer.
Excessive 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 floats move freely and do not
contact pit, piping or each other.
B PUMP STARTS TOO
SOON
Float "ON" point is adjusted too
low.
Refer to STEP 2.
C PUMP WILL NOT SHUT
OFF
Float is obstructed. Inspect float operation and correct problem.
Float "OFF" point is too low. Refer to STEP 2.
Foot Valve above water level. Adjust Float - Refer to STEP 2.
Internal valve diaphragm vent
hole is plugged with debris.
Turn off 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.
D
PUMP OPERATES BUT
DELIVERS LITTLE OR NO
WATER
Debris around Intake. Clear debris from pit and foot valve strainer.
Inadequate incoming water pres-
sure.
Check incoming water line for closed valve or low
water pressure.
Blockage in discharge pipe. Remove pipe and flush out debris.
Foot Valve above water level. Adjust Float - Refer to STEP 2.
Vertical lift too high. Change discharge piping or contact technical service.

Pump capacity varies due to: Inlet Water Pressure, Working Water
Pressure, Discharge Elevation, Number of Pipe Fittings, Inlet and
Outlet Pipe Size, Fluid Viscosity, Degree of Water Clarity, Water
Temperature. The flow rates in the chart are approximate values.
NOTE: Some districts may require a reduced pressure principle
backflow preventer per ASSE Standards 1013. Check Local Codes.
