The Sump and Installation

If your basement does not currently have a sump installed, it would be necessary

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.
