The outlet pipe that connects to the three-inch main sewer line is usually two inches in diameter. The sewage ejector pump vent runs from the sump pit and either runs up through the roof, or it can be connected to an existing vent stack. Sewage Ejector Pump System RequirementsĪ sewage ejector pump installation requires a vent in order to equalize the pumping pressure and to serve as an outlet for gasses from the sewer. The float will drop down as the level in the basin reduces, and the pump will turn off. When the sump basement level reaches a certain level, the movable float will start the pump and pump the waste out of the basin and to the septic or sewer line.

The sump basin can collect up to thirty gallons of waste which flow into it from the sloped drain lines in the home. In fact, they operate exactly like a groundwater sump pump, except it pumps out sewage and not ground water. Sewage ejector pumps should be installed in the sump basin below grade. Not all basements require sewage ejector pumps, however, when the sewer lines running to the municipal sewer on the street are higher than that of the fixture inside the home, the ejector pump can help move waste to the sewer to ensure the proper flow inside the sewer line. Drain wastewater uses gravity to eject it from the house, and in these instances, the pump-up ejector elevates the wastewater to ensure it flows properly.
