Shut-off Head:
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.

suitable for the installation, in accordance with the local plumbing code, such as a reduced pressure
principle backflow preventer (RP). Alternately, consult the local plumbing and health codes or the

Sump water is non-potable. To reduce the risk of contamination of the potable
water supply, the Home Guard Max must be installed with a listed backflow device

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.
Turn off water supply to pump. Fill pit with water until the
foot valve is submerged. Turn on water supply and activate
float by hand. Allow pump to run for 3-5 seconds and
release float before the foot valve is above the water level.
Pump should shut off normally.
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.
