How Sewer Ejector Pumps Work and Why You Need One

How a Sewer Ejector Pump Works

A sewer ejector pump is essential when wastewater from toilets, sinks, or laundry rooms is located below the main sewer or septic line. Here’s how it works:
• Wastewater flows into a sealed ejector pit or basin.
• A float switch detects the water level and activates the pump.
• The pump pushes wastewater up through a discharge line to the main sewer.
• A check valve prevents backflow into the pit.
• The system automatically shuts off once the pit is drained.


Key Components of a Sewer Ejector Pump System

Understanding the parts of the system helps you recognize when service is needed:
• Pump Motor – Typically between ½ to 1 horsepower for residential systems
• Ejector Pit or Basin – Collects wastewater until the pump engages
• Float Switch – Activates the pump when wastewater reaches a certain level
• Discharge Pipe – Routes waste to the sewer or septic line
• Check Valve – Stops wastewater from returning to the pit
• Vent Pipe – Directs gases to the home’s vent stack for safe ventilation


Do You Need a Sewer Ejector Pump?

You likely need a sewer ejector pump if:
• You’re installing plumbing below the main sewer line, such as in a basement
• You’re remodeling or adding a new bathroom to a lower level
• You’ve experienced slow drains or sewage backups in downstairs fixtures
• Your septic system is higher than your plumbing fixtures and requires a lift
