If your bathroom or laundry room sits at a lower level than your municipal; sewer system or septic tank, then proper flow of wastewater into the sewer line or septic tank will be impossible.
However, installing the best sewage pump in your bathroom can help solve this problem for good.
That said, it’s important to note that the market is filled with a variety of pump options. They come in varying materials, sizes, horsepower, prices, etc., which makes it quite tricky to choose the right model for you.
The following post will take you through all the crucial info you need to know about sewage pumps before buying as well as the 10 top-rated pumps you can get on the market today.
What’s a Sewage Pump
A sewage pump, otherwise referred to as sewage ejector pump, is a type of pump designed to facilitate smooth flow of sewage liquids and solids from one point to another.
Sewage systems usually operate on gravity—where the sewage flows downhill (from a high level to a low-level location) from your bathroom, laundry room, or any other plumbing fixture and enters into the septic tank or the municipal sewer line.
However, if your bathroom or laundry room sits at a lower level than the sewer line or septic tank, the flow of wastewater by gravity becomes impossible. Most of the bathrooms located in the basement areas are the main culprits here.
This is where the sewage pump comes in:
It forces the wastes—both liquids and solids—to flow against gravity and into the sewer system or the septic tank.
Sewage pumps come in many options. Some are manual; others are automatic. And some have the dual (piggyback) mode. The best pump for you should depend on your specific needs and preferences.
IMPORTANT: We highly advise you against going for the manual models. This is because these models require you to manually turn them on or off as the need arises, creating a possibility of sewage overflow inside the sewage basin.
Since this pump remains submerged most of the time, it also goes by the name submersible sewage pump.
Now let’s take a closer look at the 10 top-rated sewage pump reviews below…

Difference Between a Sewage Pump and a Sump Pump
Both the sewage pump and sump pump are handy devices used in homes to help drain wastewater properly. Both are meant for installation into the home septic system.
However, the two types of pumps have clear-cut differences—right from the way they function to the type of care they require.
Below, we discuss the key differences between a sewage pump and sump pump:
1. Intended use
The primary function of the sump pumps is to remove naturally occurring water or any other water in your home that can lead to flooding. This is the reason why you’ll find these pumps popular in homes or areas that are prone to flooding.
As you all know, not taking care of flooding water can lead to costly damages to your home structures and finishes, which explains why a sump pump is crucial.
The sewage pump, on the other hand, is designed primarily to remove sewage from your sum pit and send it to city sewer line or septic tank. Sewage pumps are usually helpful when you have a bathroom or laundry room sitting below the level of the sewer line, making it hard for the wastewater to flow through gravity. The pump will force the wastes to flow against gravity.
2. Power options
A sump pump is powered by electricity. In case of power outage, however, it gives you the option of using a backup battery. This is unlike the sewage pump which can only be powered by plugging it into an electrical outlet.
3. Type of waste
The type of waste that the two types of pumps can handle also varies. Remember we’ve said earlier that sump pumps are intended for removing excess water. This is to say they can only handle liquid waste and nothing more or less.
When it comes to the sewage pumps, the story is different. These pumps are capable of handling not just liquid waste but also the solid waste. In fact, they can handle solid wastes as large as 2 inches or even bigger.
NOTE: This sharp contract in the type of materials the two pumps makes it easy to understand why you can NOT use a sump pump in the place of a sewage pump.
The last basic difference between the two pumps is the care attention they require. The sump pump requires regular maintenance to continue functioning at its best and for an extended lifespan.
If you’re using the pump in a flood-risk area, then you’ll need to inspect your even more frequently.
As for the sewage pumps, they don’t require any maintenance. This is a relief to the homeowners as it’ll save you time and energy that you can invest in other helpful activities.
However, keep in mind that you might be forced to inspect your pump if it fails to activate or when solid wastes block the unit from channeling. Failing to act quickly in such scenarios can lead to sewage flooding.
What To Look For Before Buying?
As we’ve said several times before, choosing the best sewage pump from the multiple options available at the market can be a daunting task. This is especially true if you’ve never used one before and don’t know exactly what to look for.
In this section, we’ll take you through a list of crucial factors that you should keep in mind when buying your sewage pump.
It’s important to look for a pump made with the highest quality materials to ensure it serves you for an extended period of time.
Most of the top-rated sewage pumps from reputable manufacturers have their housing and parts made from the cast iron material which has superior durability.
The economic models feature thermoplastic construction which also offers excellent quality.
Another important thing to look for in a sewage pump is the motor horsepower rating.
For those who don’t know, the horsepower (abbreviated as H.P) is a term used to measure the power of the pump motor.
A pump with higher horsepower rating means more power (and faster pumping action).
If your home has more people, say more than 4 people, we advise you to go for a pump with greater horsepower as you’ll need to pump more water minute and more frequently.
Surprisingly, the lifetime of your pump will also depend on the number of hours you run it. That is, if you buy a pump with less HP and run it more than it’s capable of handling, you’ll shorten its lifespan.
The typical horsepower rating found in most sewage pumps for home and residential applications is ½ H.P
Pump Flow Rate
The pump flow rate—expressed in gallons per hour or minute—refer to amount of waste materials in gallons that a pump can move in an hour.
The flow rate is a direct result of the motor horsepower…and is affected by the elevation between your home sewage basin or septic tank and the main sewer line.
The higher the elevation, the lower the flow rate becomes.
If you make the mistake of buying a pump with less GPH, it’ll force the pump to handle more than the manufacturer specification. And this leads to a shorter lifespan.
Judging from the top 10 pumps we’ve outlined in this guide, we can safely say that the cost of sewage pumps varies from model to model.
You’ll find some models on the lower end and some on the higher end of the cost spectrum. The higher the price, the better the quality, features, and performance of the pump.
For the homeowners on a tight budget, you should be careful not to fall for the low-cost cheaply built that might end up disappointing you. Just put the extra effort into your research, and you’ll find a good quality model that fits your budget.
If you want to be 100% sure that you’re buying a product made of quality and dependable performance, then buy from the respected brands in the industry.
Some of the most reliable brands include Zoeller, WAYNE, Liberty Pumps, and Superior Pumps.
Such companies have a track record of producing top quality products that rarely disappoint in terms of performance.
Sewage Pump Installation: How To Do It On Your Own?
Now that you’ve finally gotten your best sewage ejector pump, you might be torn between hiring a professional plumber to install it for you or do it on your own.
GOOD NEWS is that the installation part isn’t as hard most people tend to think. With a proper set of instructions and the willingness to do it, you can get the job done easily and quickly.
Let’s discuss the crucial installation steps you need to follow to install a typical sewage pump:
Step 1: Setting up the basin
The first thing you need to do is install the basin where water will be drained into whenever you flush the toilet. Mount the basin on the floor and attach your pump to it. Ensure the pump isn’t wobbly to prevent it from tipping or falling off when hit by water. The basin too ought to be securely attached to the ground to prevent any cracks or leakage.
If you have the septic tank or basin already installed in your home, then this step will be easier for you as you’ll only need to attach the pump.
Step 2: Installing the float switches
Once you’ve your pump in place, you can then go ahead and set the float switches to detect when the pump should start pumping. The switch works in a way that when the wastewater reaches it, it’ll automatically turn on the pump—suctioning the wastes through the check valve and into the basin or septic tank.
Confirm that the vent and discharge outlets aren’t plugged or clogged for efficient pump functioning.
Step 3: Piping and testing
You can choose to make the side inlet piping with a 4-inch pipe, or 3-in if you prefer a smaller pipe.
When the piping is done, test your toilet and drains to ensure they’re working well. Ensure there are no signs of yard flooding or leaking for the basin or pump. In case of any leaks, make the necessary readjustments or add some hard hold glue of your choice.
NOTE: This is a general installation guide for all pumps out there. For more details on how to set up your specific pump, we encourage you to go through your user manual.
How Long Does It Last?
There’s no set lifespan for sewage pumps. Keeping in mind that these pumps are submerged in in harsh environments, they’re likely to wear out easily and quickly.
BUT…not so fast! Most homeowners have confessed about their pumps lasting as long as 7-10 years or even more.
How much the pump runs can also affect its lifespan. If you have a smaller pit and many people in your home, then you’ll expect your pump to operate for more hours than houses with larger pits and fewer people. A pump that works 2 times harder will have a shorter lifespan than one that operates less frequently.
Overall, picking a pump that’s appropriately sized to your specific application, installing it correctly, and taking good care of it will help extend its lifespan.
The best sewage pump comes handy when you’ve got a basement laundry room or bathroom where the flow of the waste liquids and solids into the septic tank or sewer system might be a challenge.
As we’ve seen from our sewage pumps guide above, these helpful devices differ in terms of the type of construction material, size, horsepower, and even cost.
To help you pick the right model that works according to your expectations, we’ve outlined a quick buying guide to show you the key features that you should look for in a sewage pump.
Our list of the 10 top-rated sewage pumps available at the market today will also point you in the right direction when buying your sewage pump.
