Understanding Sewage Ejector Pumps: What They Are and Why You Need One
A plumbing system in your modern home is likely a great feat of innovation when you actually begin to examine the key features and functionalities of the system itself. Handling wastewater efficiently is no simple task. In this post, we’ll be going over the importance of having a sewage ejector pump if certain areas of your home happen to be below the main sewer line, such as basements, where gravity alone won’t quite be able to move the wastewater from point A to point B. A sewage ejector pump is able to assist with this process. While a sewage ejector pump is certainly not immediately thought of as a solution when it comes to wastewater management in low-lying areas, we hope this guide will bring about a greater understanding of the device and explain just how much of a critical role it plays in below-grade plumbing systems.
Whether you’re a homeowner, a contractor, or a curious reader; this guide will allow you to walk away with a better understanding of all things sewage ejector pumps. Feel free to contact us should you have any questions and we’ll do our best to help you find the right solution for your problem.
What Is a Sewage Ejector Pump?
A sewage ejector pump is essentially a device which is designed to transport wastewater and solid waste from a low-lying area of your home, such as a basement, up to your home’s main sewer line or septic tank. If you’ve ever flushed a toilet within a basement bathroom, or drained a sink in a low-lying area of your home; it’s quite likely a sewage ejector pump is utilized to do the heavy lifting behind the scenes.
Unlike standard sump pumps, which handle groundwater and rainwater, sewage ejector pumps are specifically designed to handle wastewater that includes human waste, toilet paper, and other organic materials. These pumps are robust, built to handle tough conditions, and essential for any home with plumbing fixtures below the main sewer line.
How Does a Sewage Ejector Pump Work?
The operation of a sewage ejector pump is quite straightforward yet equally fascinating:
Collection: Wastewater flows from your plumbing fixtures (toilets, sinks, showers, washing machines, etc.) into a sealed holding tank called a sump basin. This basin is typically buried in the floor of your basement or other low-lying area.
Detection & Activation: Inside the tank is a float switch, much like the one in a sump pump. When the water level in the tank rises to a preset point, the float switch activates the sewage ejector pump.
Pumping: The pump’s motor kicks on, and its impeller forces the wastewater (including solids up to 2 inches in diameter) up through a discharge pipe. This pipe connects to your home’s main sewer line or septic tank.
Shutoff: Once the water level in the basin drops, the float switch deactivates the pump until it’s needed again.
Who Needs a Sewage Ejector Pump?
Not every home will require a sewage ejector pump, yet when they are required, they're very much a necessity. Below are some examples of where a sewage ejector pump will likely be needed:
Homes with Basements
Homes which have basements where there are bathrooms, laundry rooms, or utility sinks with a direct water connection will be a common reason to install a sewage ejector pump. These fixtures within your basement are typically below the sewer line which prevents gravity from moving the wastewater from point A to point B without the assistance of a sewage ejector pump. With a sewage ejector pump, wastewater is assuredly moved upward and onward.
Low-Lying Homes
Low-lying homes may require a sewage ejector pump, even if they do not have a basement; especially if they're located on a flat or low-lying land area prone to flooding during heavy rainfall. The main sewer line may be above the level of the plumbing fixtures themselves and this could lead to some potential issues arising in the event there’s not a sewage ejector pump installed.
Additional Living Spaces
If you happen to have an ADU (additional dwelling unit), which could include everything from an in-law suite, a rental unit, or another additional living space which happens to be below a certain level on your property; you’ll want to consider installing a sewage ejector pump. The sewage ejector pump will provide your ADU with the right level of plumbing services it needs to have the best outcome possible, even in situations where there’s excess water attempting to overtake your ADU.
Septic Systems
If your home has a septic system, more so for those with septic tanks located at a higher elevation, a sewage ejector pump will help to ensure the waste reaches the septic tank efficiently and effectively.
Key Components of a Sewage Ejector Pump System
There are multiple components of a sewage ejector pump system which are equally important in the overall operation of the sewage ejection process itself:
The Pump Itself: The sewage ejector pump itself is obviously very important, as it powers the system. Most residential sewage ejector pump systems are submersible and sit within the sump basin itself.
Sump Basin: A sump basin is a sealed tank which collects wastewater. These basins are commonly made of a heavy-duty plastic or fiberglass and will come with a cover to properly contain the odors produced.
Float Switch: The float switch is the mechanism which activates and deactivates the sewage ejector pump system based on the water level within the basin itself.
Discharge Pipe: A discharge pipe connects the pump to your home’s main sewer line or septic tank system. A check valve is often included to prevent the action of backflow.
Vent Pipe: A vent pipe is one of the most crucial parts of the sewage ejector pump system, as it prevents pressure buildup in the tank and allows gases to safely escape. Without this component of the sewage ejector pump system, there would be nowhere for the gases to go.
Choosing the Right Sewage Ejector Pump
As a homeowner, selecting the right sewage ejector pump is usually a matter of finding a reliable replacement for the pump you currently have installed. That being said, here's some things to look out for:
Outlet Diameter
When shopping for a replacement to your existing Ejector pump, ensure the outlet size of your new pump matches the outlet size of your current pump so you're less likely to have to re-plumb any pipes to fit the new model.
Material
Durability is one of the key factors for a sewage ejector pump. Most newer models are constructed out of cast iron or stainless steel will be able to resist corrosion and wear and tear.
Solids Handling
The sewage ejector pump should be able to handle waste solids up to two inches in diameter (the standard for residential use). Avoid any pumps with a smaller solids rating, unless your current ejector pump is a grinder type.
Alarm Systems
If you're replacing your ejector pump, and don't already have one, we recommend installing an alarm control panel, which will be able to alert you if there are higher than average water levels or malfunctions. This feature alone can save you thousands of dollars in damage and reduce stress immensely.

Cost of a Sewage Ejector Pump System
The cost of a sewage ejector pump system will include both the pump itself and installation costs:
Pump Cost: A high-quality residential pump will range in price from $300 to $800+, ultimately depending on the horsepower, materials, and features
Installation Cost: Hiring a professional plumbing company to install the system typically costs between $500 and $1,500, and could be higher depending on your home's location, layout, and other variables.
While this may seem to be a significant investment, it’s very much worth it to avoid sewage backups and the damage they may end up causing.
Maintaining Your Sewage Ejector Pump
Establishing proper maintenance protocols will likely extend the life of your sewage ejector pump by many years. Follow these helpful tips to ensure your system is running at its highest level of efficiency and effectiveness:
Routine Inspections
Check the pump, float switch, and discharge pipes every six to twelve months (depending on usage patterns) to ensure everything is in good working order.
Cleaning
Remove any grease, hair, or debris which may have accumulated in the sump basin. Be sure to always turn off the power before cleaning.
Testing the Float Switch
Manually raise the float switch to test whether the pump activates and shuts off as intended.
Preventing Clogs
Avoid flushing items such as sanitary products, wipes, or non-degradable materials, which will likely cause damage to the pump.
Professional Servicing
Have a plumber inspect the system annually to proactively catch any potential issues early on.
Common Issues & Troubleshooting
Even with proactive, regular maintenance, sewage ejector pumps may experience problems. Here are some of the most common issues and how to properly address them:
Pump Runs Constantly
Cause: A stuck float switch or blockage in the discharge pipe
Solution: Check and clean the float switch or pipes
Pump Doesn’t Turn On
Cause: Power failure, faulty switch, or motor issues
Solution: Check the power source, replace the float switch, or consult a professional
Foul Odors
