How Sewer Ejector Pumps Work and Why You Need One
​​
How a Sewer Ejector Pump Works:
-
Wastewater flows into a sealed ejector pit.
-
A float switch activates the pump when the pit fills.
-
The pump pushes wastewater up through a discharge line.
-
A check valve prevents backflow.
-
The pump shuts off automatically after draining the pit.
Key Components:
-
Pump Motor – Typically ½ to 1 horsepower for residential systems
-
Ejector Pit/Basin – Holds wastewater until it reaches pump activation level
-
Float Switch – Turns pump on and off based on water level
-
Discharge Pipe – Carries wastewater to the sewer or septic system
-
Check Valve – Prevents wastewater from returning to the pit
-
Vent Pipe – Releases gases through your home’s vent stack
