80 PSI
Shut-off Head:
60 PSI
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.

REMEDY
Check incoming water line for closed valve, low water
pressure or clogged filter/strainer.
Install regulator and reduce pressure below 100 PSI
with valve closed.
Clear debris from pit and foot valve strainer.
Move pumps so that the floats move freely and do not
contact pit, piping or each other.
Refer to STEP 2.
Inspect float operation and correct problem.
Refer to STEP 2.
Adjust Float - Refer to STEP 2.
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.
Clear debris from pit and foot valve strainer.
Check incoming water line for closed valve or low
water pressure.
Remove pipe and flush out debris.
Adjust Float - Refer to STEP 2.
Change discharge piping or contact technical service.
