A sewage ejector pump is used when a bathroom, laundry room or any other type of plumbing fixture is located below the level of the main sewer or septic line flowing from the house. Since wastewater depends on gravity, plumbing systems in which these fixtures are located below the level of the main sewer line all require some means of lifting the wastewater to the gravity sewer, so it can flow properly.
Ejector pumps are used in buildings with basement bathrooms or laundry rooms. Not all locations require them, but when the municipal sewer lines running to the street are at a higher level than the fixture, the ejector pump serves to pump both liquids and solids up into the sewer line, so it can flow properly.
Sewage ejector pumps are meant to sit in a ejector basin that is cut and dug into the ground below grade. This basin collects and holds about 30 gallons or more depending on the size of the building. Drains from the various fixtures in the basement area are sloped down into the side of the basin, and when the level of wastewater in the basin reaches a a set height, a moveable float switch starts the pump. The wastewater is then pumped out of the basin and up to the level of the sewer line. Once the level in the basin goes down, the float drops back down and turns off the pump until the next time the basin fills.
