Sewer Ejector Pumps

Sewer Ejector Pumps

What is the difference between a Sewer Ejector Pump and a Septic Lift Pump? A sewer ejector pump moves sewage from the residence into the septic tank. They are designed to handle solids up to 2” diameter. These pumps are designed to pump high volumes of sewage (up to 200 gallons per minute). Sewer ejector pumps are made for short pumping distances. A septic lift pump moves wastewater from your septic tank into an area where it can be filtered back into the ground. These are very common with “Mound” septic systems where the septic field is located at a higher elevation than the septic tank.

What is the difference between a Sewer Ejector Pump and a Sewer Lift Pump?

For all intensive purposes, sewer ejector pumps and lift pumps are the same. They are used when any type of plumbing fixture (laundry drain, bathroom line) is located below the grade of the main sewer or septic line. The pump helps lift the grey and or black water from your home out into the main sewer line. If you are looking to add a basement bathroom or relocate your laundry room from a main level to the basement, a sewer ejector or lift pump may be a necessary addition to your project.

How does a sewage ejector pump work?

Waste water from various basement or below grade fixtures run into a sump basin. The ejector pump is installed within the basin. Once the waste material reaches a specific level within the basin a float switch is activated turning on the pump. The ejector pump moves the waste water out of the basin and into the main sewer line until the float switch falls and turns the pump off.

How does a sewage lift pump work?

A sewage lift pump works on the same design as the ejector pump. Lift pumps will lift waste water from the pump basin out of the home and into the main sewer line. The lift pump is installed into the pump basin which would be installed at the lowest point of the sewage basin.
