I prefer a Liberty sewage ejector pump with a 25-foot-long power cord. They are able to reach a suitable electrical outlet when the pump station is outdoors.
Also, many sewage ejector pumps are installed in a refinished basement bathroom. In that situation it is cheaper to buy a longer power cord than have a new electric outlet installed. Of course, if an electrician is rewiring the basement, have proper outlets placed where the 10 foot cord will work.

Liberty Sewage Ejector Pump Power Cord Considerations
All Liberty pumps have a quick-disconnect power cord. The power cord can be changed very quickly without breaking the waterproof seals on the motor. This is important because sewage will chemically attack any power cord.
So, the power cord will need to be replaced before the Liberty sewage ejector pump needs replacement.
Liberty pumps do not have a piggyback power cord. The piggyback power cord is part of the float switch cord. The piggyback power cord for the float switch is plugged into the electrical outlet. Then the pump power cord is plugged into the back side of the switch’s piggyback electrical plug.
This means that only one electrical outlet is needed to power both the Liberty sewage ejector pump and the float switch.
What Size Liberty Sewage Ejector Pump Do I Need?
The most commonly purchased Liberty sewage ejector pump is the 4/10 HP pumps. They have that extra power needed to pump solid sewage that a 1/3 HP effluent pump cannot.
Also, the 2-inch discharge pipe is very important. It can pass the 2-inch solid wastes that 1.5-inch effluent discharge pipe cannot.
So, the 4/10 HP sewage pumps will get the sewage out of the house to a nearby septic tank. However, if the septic tank is some distance from the house foundation go with the ½ HP or ¾ HP Liberty sewage ejector pump.
Additionally, the higher in elevation the sewage must be pumped, the more horsepower that is needed. Check the comparison chart to see how many gallons per hour each pump can handle at the lift height you require.
Also, if more than one toilet is flowing to the pump station, homeowners better get the ½ HP or ¾ HP sewage ejector pumps.
Note: These are sewage ejector pumps, not grinder pumps. Grinder pumps actually chew up everything before pumping it out. Grinder pumps are much more expensive sewage ejector pumps.

The three different impellers shown below are for the Liberty sewage ejector pumps:
4/10 HP Series LE40
½ HP Series LE50
¾ HP Series LE70
One impeller is not necessarily any better than the others. However, because of the way they are made they require different materials for their construction. Each of them has stood the test of time and I would not worry about which one I bought.
Should I buy An Automatic Ejector Pump?
The simple answer is “yes” but how you get there is the question.
If installing a brand new system buy an automatic ejector pump with the right length power cord for your needs.
You can buy one of the manual models to replace your old pump and continue using your existing tethered (wide angle) float switch. However, any float switch from any manufacturer is usually the first part to fail. So, you might want to buy an automatic pump and keep your existing float switch as a backup.
If you want the manual 1/2 HP Liberty Pumps LE51M-2 Pump model with the 25 foot power cord, then also order the 25 foot float switch. At the time of writing the picture at Amazon shows a bathroom and not the float switch. Just ignore the picture, because it is the correct product.
Any replacement part you need can be purchased through distributors or directly from Liberty Pumps.
1/2 HP Liberty Sewage Ejector Pump With Alarm System
Homeowners need to know if the sewage pump has stopped working. So, consider buying the 1/2 HP Liberty Pumps LE51A sewage ejector pump shown below. It has a 86 decibel alarm horn and a red LED warning light.
The warning system works on 115 volts but also has a 9 volt battery backup power supply. The alarm has its own tethered float ball that activates the alarm when the sewage level is too high.
