The Sump and Installation
If your basement does not currently have a sump installed, it would be necessary to
check local plumbing codes as to the acceptable type of sump that may be used.
Materials commonly specified are: clay tile, fiberglass, steel, concrete and polyethylene.
It may be necessary to cut a hole in the basement floor and excavate
for the sump.
Plumbing and electrical contractors could advise you on proper installations of drain
tiles, sump, pump and electrical service. EBARA recommends that a solid sump base
be provided. The sump is fed by drain tile placed around the outside and/or inside base-
ment walls at the footings. If applications where a gravel base must be used, to relieve
hydraulic pressure under the basement floor, be sure to provide a permanent and solid
base for the pump (bricks or a steel plate). A sump cover capable of supporting 200
pounds should be employed to contain odors and for obvious safety reasons.
Electrical Installation
Electrical service for any sump pump installation must be grounded and separately fused
or breakered directly from the entrance box with a single grounding type receptacle at
the pump. The receptacle should not be less than four feet above the basement floor for

safety reasons. You should never touch a sump pump or discharge piping while the
pump is connected to electrical power and water is present. The pump should be
disconnected from the electrical source before handling in all cases.
Discharge Piping Installation
To assure the maximum performance from your sump pump, the discharge pipe size
and piping fittings should not be smaller than the discharge port of the pump. Smaller
pipe will add to friction losses and reduce the capacity of the pump. Normally accepted
materials are galvanized pipe, rigid plastic pipe or
acceptable flexible pipe or hose. A piece
of flexible hose between the pump discharge
and the discharge piping will provide for ease
in alignment, reduce vibration and noise, and will act as a union when it is necessary to
remove the pump. Where the discharge pipe is long, a check valve is often employed to
prevent the water from flowing back into the sump when the pump turns off. If the discharge
is directed into a sanitary sewer, a suitable anti-siphon device or a free flow check valve
should be inserted in the line to prevent backflow into the pit. Sump pumps are not
designed to handle raw sewage. Do not attempt to adapt one for this type of application.
A sewage ejector pump especially designed to handle solids must be used.
Pump Installation
When the sump, electrical and discharge plumbing installation is complete and ready for
the pump, clean all solid debris from the pit. Complete the plumbing connection to the
pump and then plug the pump into the electrical outlet. A few extra minutes to test the
sump pump installation are now in order. Fill the sump with water, note the turn on and
turn off level of the pump, and the pumping cycle. This will allow you to calculate the
approximate discharge flow of the pump system. If everything is operating properly,
install the sump cover.
Pump Selection
The pump should be of sufficient capacity and head to satisfy anticipated use require-
ments. Capacity is determined by a fixture unit value if effluent is drained to sump basin.
Your local Wholesaler can assist you in fixture unit values.
Basement perimeter water intrusion varies by area and region. Typically a 1/3 HP or 1/2
HP DRAINAGE PUMP WILL EVACUATE MOST HOME SUMP PITS.
Commercial and industrial drainage applications require that calculations of pumping
volume and pumping head be performed to determine the proper size pump is applied.
NOTE: Pumping volume may vary seasonally due to rainfall and area run-off.

Basin and Cover
The basin should not be less than 18 inches in diameter and 24 inches deep.
Larger diameters are advisable in instances of increased pump capacity requirements:
The basin should be located such that all water flows into the basin due to gravity.
Outdoor installations should be at a sufficient depth to ensure protection from freezing.
Maintenance Tips
•Every three or four months:
1) Clean the pump screen or inlet opening. If your sump collects the discharge
from an automatic washing machine, cleaning will be required more often. (Before
removing the pump be sure to disconnect the unit from electrical power; and
reconnect after completion of cleaning);
2) Pour enough water into the sump to cycle the pump and assure its proper
functioning.
•Annually:
Remove and clean the pump. Clean the sump pit also.
WARNING
Before handling this pump, always disconnect
the power first.
This pump should only be serviced by a qualified person or a factory
trained person.
CAUTION
This instruction manual includes necessary items for installation, operation and maintenance.
Read this manual carefully to ensure correct installation,
operation and maintenance.
Be sure to keep this instruction manual on hand for future reference.
