Home Guard data by Zoeller Pump Company

Typical Installation with Submersible Pump

The HOME-GUARD pump can be installed as a standby to an electric sump pump (see sketches). However, a check valve is required between the electric pump and the HOME-GUARD.

VERY EASY TO INSTALL
The pumping capacity increases with household water pressure and flow.

DISCHARGE HEAD:
15 ft. (4.5 m) maximum.

WATER PRESSURE:
40 PSI (1.5 bar) minimum with valve open.
80 PSI (6.9 bar) maximum with valve open.
95 PSI (8.3 bar) with valve closed.

Typical Installation with Submersible
Pump and Separate Discharge Pipe

EFFICIENCY:
At an eight-foot static head and a supply pressure of 40 PSI at (A) with water flowing, it takes one (1) gallon of supply water to remove one gallon from the sump. As the supply pressure increases with the static head constant, less supply water is required.

* Pump capacity varies due to: Inlet Water Pressure, Working Water Pressure, Discharge Elevation, Number of Pipe Fittings, Inlet and Outlet Hose Size, Fluid Viscosity, Degree of Water Clarity, Water Temperature, Cleanliness of Intake Screen.
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.
