What is a Sewer Ejector Pump?

A sewer ejector pump is a specialized piece of equipment designed to move wastewater from a lower elevation to a higher one, where it can then flow into the main sewer line via gravity.

Essentially, it’s a powerful pump housed within a sewage basin.

When wastewater fills the basin to a certain level, a float switch activates the pump, which then forcefully ejects the sewage upwards into the discharge pipe, allowing it to connect with the municipal sewer system.

The Necessity of Ejector Pumps

Sewer ejector pumps are commonly used in situations where plumbing fixtures are located below the level of the main sewer line.

Basements with bathrooms, laundry rooms in below-grade spaces, or additions built lower than the existing sewer connection are prime examples of scenarios requiring an ejector pump. Without one, wastewater would have no way to reach the sewer line, leading to unsanitary conditions and potential backups.

This knowledge is essential for informed decision-making, whether you choose DIY installation or opt for professional assistance.

How the Sewer Ejector Pump Works: Lifting Wastewater Against Gravity

The fundamental principle behind a sewer ejector pump is simple: it overcomes gravity. Fixtures located below the level of the main sewer line, such as basement bathrooms or laundry rooms, cannot rely on gravity to drain wastewater.

The sewer ejector pump system collects this wastewater in a basin and then forcefully pumps it upwards to a point where it can connect with the main sewer line and flow away naturally. It’s essentially a mini-lift station for your home’s wastewater.

Key Components of the System

Understanding the individual parts of the system is important for ensuring successful installation and troubleshooting.

• Sewage Basin: This is the holding tank, usually made of durable plastic or fiberglass, that collects all the wastewater from the lower-level fixtures. It must be appropriately sized to handle the anticipated volume of sewage.

• Float Switch: This is the sensor that detects the water level in the basin. When the water reaches a predetermined level, the float switch activates the pump. A malfunctioning float switch is a common cause of pump problems.

• Check Valve: Located on the discharge pipe, the check valve prevents wastewater from flowing back into the basin after the pump shuts off. This is crucial to prevent backflow and maintain system efficiency. Incorrect check valve installation is a common and serious mistake.

• Discharge Pipe: This pipe carries the wastewater from the pump up to the main sewer line. It must be properly sized and supported to handle the pressure and volume of the flow.

• Vent Pipe: The vent pipe allows air to enter the system, preventing a vacuum from forming and ensuring proper drainage. It also vents sewer gases outside of the house. Proper venting is essential for a healthy and functioning system.

• Electrical Wiring: The pump and float switch require a dedicated electrical circuit. All wiring must be done according to local electrical codes and with appropriate safety precautions. Improper wiring is a significant safety hazard and can damage the pump.

When is a Sewer Ejector Pump Needed? Common Scenarios

Sewer ejector pumps are typically required in the following situations:
