How Does a GE Ejector Pump Work?

With a bathroom in the basement, you'll need an ejector pump.

Basements with bathrooms often contain an ejector pump typically installed when any sewage or wastewater, is created below the point where sewage leaves your home near ground level. Your General Electric ejector pump works much like other pumps to rid your home of things that gravity normally handles.

The Motion

Your GE ejector pump is actually a grinder and a pump at once. Effluent enters the subfloor housing for your pump through a drain pipe from your toilet or shower, then is ground to a slurry that's then pumped upward into a pipe that carries the waste to the main waste line leaving your home.

The Pipes

Though the sewer pipe leaving your home is typically 3 inches in diameter or more, the pipe leaving the ejector pump is often smaller, at 2 inches. Also connected to your GE ejector pipe's sub-floor container is another 2-inch pipe meant for ventilation. The motor is powered via a 12-volt electrical connection.

Pipe Specifics

The 2-inch pipe that leaves your GE ejection pump headed for your main waste line contains a union and check valve along the way to impede the flow, if repairs or adjustments are necessary.
