A sewage pump also called a sewage ejector pump, is a very important device as it keeps all of the unwanted, dirty water where it belongs. It’s designed to pump both liquids and solids up to 2 inches in diameter. The most common application for sewage pumps is the installation of basement bathrooms or laundry rooms. Because the basement is below grade, or situated below the sewage line entrance, the sewage pump is needed to get waste and water out of the house.
There are several types of sewage pumps available. They come in a variety of materials, sizes, horse powers, and prices. Some are submersible, some are plastic, and some are cast iron and stainless steel. Some sewage pumps have float switches, while others are available in 1/3 HP, 1/2 HP, 3/4 HP, 1 HP and there is a pump rated up to 5 HP. Some pumps can cost as much as $800, while others can cost a little under $150.

The Zoeller M267 Waste-Mate Sewage Pump is the best sewage pump that money can buy. It has been recommended by 95 percent of customers who purchased.
The Zoeller M267 Waste-Mate is one of the most popular sewage pumps in the US market. It is designed to be used in a variety of septic, sump, and lift station applications and offers a wide range of versatility capable of pumping 2 inches solids up to 21.5 feet total dynamic head. It has cast iron construction for the vital parts, such as motor housing, base, and volute – that are essential if you want a pump to last for a really long time.
This sewage pump is a beast but weighs only 47 pounds. It has a 2-pole mechanical vertical float switch and a non-clogging vortex impeller. The vertical float switch is great if you have a sump pit that is too narrow and/or too shallow for a tethered float switch. It is going to operate the pump more often but will not allow the water to get too deep. The non-clogging vortex impeller allows the pump to pass solids with ease. The Zoeller M267 also has an engineered plastic impeller with metal insert, and are not affected by the material in the basin. It has a discharge size of 2 inches and a flow rate of 128 GPM (gallons per minute).
The Zoeller M267 come as an automatic sewage pump. An automatic sewage pump means that a switch is wired to the sewage pump to turn it on or off at appropriate water levels. Automatic switches include pressure switches, low-level pressure switches, float switches, and a solid state water sensor called field-effect. Using an automatic sewage pump has 2 advantages:
1. The pump will automatically switch off upon detecting the lack of supply water, protecting the pump from incurring any damage.
2. The pump will try to re-start at regular intervals to check whether water has become available.
Furthermore, this sewage ejector pump is an electric submersible pump. That means It can be fully submerged in water. The major advantage to a sewage submersible pump is that it never has to be primed, because it is already submerged in the fluid. Sewage submersible pumps are also very efficient because they don’t really have to spend a lot of energy moving water into the pump. Water pressure pushes the water into a submersible pump, thus “saving” a lot of the pump’s energy.
Overall, Zoeller is one of the best brands of the sump and sewage pump in the world. It’s the brand you can definitely trust. And the Zoeller M267 Waste-Mate Sewage Pump is the best sewage pump available, it will give you “peace of mind” for many years to come.
2. Liberty Pumps LE51A 1/2-HP Submersible Automatic Sewage Pump | Most Powerful
- 160 gallons per minute, 1/2 HP Single phase, 115V.
- Heavy cast iron construction
- Oil filled, thermally protected motor
- Permanently lubricated bearings
- 2-vane, corrosion resistant HYTREL impeller
- All stainless steel fasteners and rotor shaft
- Quick-disconnect 10-feet standard power cord allows replacement of cord in seconds without breaking seals to motor
- 3-year warranty
Liberty Pumps makes some of the best commercial-grade sewage pumps for residential and light commercial applications. Our experts tested the Liberty Pumps LE51A sewage pump, and found that it works almost as well as our top pick. Like Zoeller M267, it has a heavy-duty epoxy-coated cast iron housing making it more corrosion-resistant for extended pump life.
The Liberty Pumps LE51A is a submersible automatic sewage pump with a 115V motor. Its efficient 1/2 HP motor with permanently lubricated bearings, stainless steel fasteners, and quick-disconnect power cord design make this a favorite choice among professionals. Other features include 2 inches solids-handling ability, a shut-off head of 25 feet, and the 10 feet quick-disconnect power cord which gives you the ability to easily replace the cord without breaking the seals.
Another advantage of this sewage pump is it’s also equipped with an adjustable wide-angle switch that has a piggyback series plug for a manual bypass operation. Therefore, if the switch fails to operate, the submersible sewage pump cord can be separated and plugged into an electrical outlet, directly bypassing the switch.
However, a few things held this model back from our top spot. It’s louder than the competition. In fact, many user reviews complain about the sound, so we’d think twice before putting it near the bedroom.
3. WAYNE RPP50 Cast Iron Sewage Pump | Best Buy
- 1/2 HP, max. flow rate is 95 gallons per minute.
- Durable, cast iron submersible sewage pump
- 2 in. NPT discharge capable of handling up to 2 in. solids
- Will replace most sewage pumps without any plumbing changes
- Piggy-back tether float switch for automatic or manual operation
- Designed for 18 in. diameter or larger sewage basins
- Pumps designed to handle 2 in. solids
- 1-year warranty
The WAYNE RPP50 Cast Iron Sewage Pump is one of the cheapest sewage pumps on the market. It’s also one of the best-selling sewage/effluent pumps on Amazon.
Even though the Wayne RPP50 pump is rated at much less flow rate than our top pick (95 gallons per minute max), it seems like it empties the sump very fast. But this one is significantly louder the Zoeller M267. This sewage pump is suitable for pumping sewage, effluent, wastewater, groundwater and other non-explosive, non-corrosive liquids with up to 2 inches solids. It includes a wide-angle float switch that turns the pump on and off as the fluid level rises and falls.
Like 2 options above, the WAYNE RPP50 is an automatic sewage pump. It is provided with a “Switch Genius” capacitive water sensor. When water is detected, the pump will start automatically. Wayne claims that their Switch Genius is a new electronic switch technology that lasts up to 5 times longer than conventional switches. Our experts tested it, and it wasn’t as good as we expected. It seems like the Switch Genius isn’t smart enough to tell when the pit is empty. If you buy it, you’d want to remove the Genius Switch and replace it with a float switch.
The WAYNE RPP50 sewage pump has a much smaller size than average ½ HP pumps, and it weighs only 23.6 pounds – is exactly half the Zoeller M267. This sewage pump is small but has plenty of power to do the job.
Bottom line, no sewage pump is going to last forever in the dirty environment. Since this pump is easy to change out and inexpensive, it is a good value for considering on an annual cost basis if it lasts at least 3 years.
