What it isA sewage ejector pump lifts wastewater from fixtures below the main sewer line, such as a basement bathroom, up to the sewer. Unlike a sump pump, it handles sewage, sits in a sealed vented basin, and failures can cause unsanitary backups.
When you need sewage ejector pump repair
- High-water alarm sounding
- Sewage odor near the basin
- Basement fixtures backing up
- Pump running constantly
How it works
- Check power and alarm
- Open the sealed basin with ventilation and protection
- Test float and pump
- Replace pump or check valve as needed
- Reseal and vent

Limits and when it’s not the right fix
- Sewage exposure requires protective equipment.
- Wipes and grease frequently cause failures.

Sewage Ejector Pump Repair: common questions
What is the difference between a sump pump and an ejector pump?
A sump pump removes groundwater. An ejector pump moves sewage from below-grade fixtures to the sewer. Ejector pumps are in sealed, vented basins and handle solids.
What should I do if my ejector pump alarm goes off?
Stop using the basement fixtures connected to it, check that the pump has power, and call for service if the alarm continues.
