Sewage Ejector Pump vs Septic Grinder Pump

The biggest challenge for most people is to figure out how to keep the sewage from building up in their basement or crawl space. It’s important to install a pump that is appropriate to your home’s needs. In most cases, if you have a sewage pumping problem in your basement or crawl space, you need to install a sewage ejector pump. You can also use a grinder pump to pump sewage, but if your sewage is too heavy, it might clog up.

If you are pumping to a pressurized sewer main, you will need a grinder pump. If you are pumping to a septic tank or a gravity-flow sewer main, you will need an ejector pump

What are Sewage Ejector Pumps?

A sewage ejector pump is a simple yet very effective mechanical device used to lift water from a septic tank or other holding tank and discharge it into a sewer system. These devices are also known as “siphon pumps” or “water lift pumps”. They are most often used in rural areas where there is no municipal sewer system, or in areas with an on-site sewage treatment system that is not working properly. The most common use for these pumps is to evacuate the tank when it is full so that the tank does not overflow and cause a flood.

Pumping sewage from your home can be done by using an electric or gas-powered pump. An electric pump is easier to use, but gas-powered pumps are more efficient. Electric pumps are powered by electricity, so they are the easiest to install. Gas-powered pumps are powered by gas, so they are the most efficient. Once you have installed the pump, you will need to connect it to a sewage line.

The use of sewer ejectors has been around for a long time. There are many different types of sewer ejectors, and the most common is the ejector pump. The two main types of ejector pumps are the submersible pump and the surface-mounted pump.

Sewage Pump Characteristics

The pump removes the wastewater from the home and sends it to the septic tank. These pumps use a vacuum action to remove the sewage from your home. They are best for homes where there is a large amount of sewage to be pumped.

  • The sewage is more likely to be moving up the sewer line.
  • Sewage pumps are available in a variety of sizes, shapes, and materials.
  • Sewage pumps can handle solids, but not very much.
  • Some sewage pumps will need to be cleaned periodically to prevent the buildup of solids.
  • A sewage pump must be placed where the sewage is going, not going because the sewage cannot be taken back and recycled.
  • The sewage is more likely to be moving toward the home or utility with the pump, rather than away from it.
  • A sewage pump with a grinder pump has higher efficiency.

What is a Septic Grinder Pumps?

Septic grinder pumps are used to remove the waste material from septic tanks, and are also known as ‘grinder pumps’. These are high-pressure pumps that run on electricity and can handle low water volume. They are available in different sizes and capacities, depending on how much sewage your septic system can hold.

They are used in septic tanks to pump wastewater or “grey water” out of the tank, and into a drain field or infiltration area where it is absorbed into the ground. They work by using an impeller or propeller inside the pump to grind up the solids in the tank and flush them out through a filter.

A grinder pump uses a revolving disc to mix the water with air. It is a self-contained unit that pumps waste from the septic tank into the sewage line. These pumps can be purchased as a pre-assembled unit or as a kit that can be easily installed. This type of pump is used to pump water from underground aquifers or wells to the surface and is less expensive than a sewage pump.

Grinder Pump Characteristics

These pumps are a great choice if you are pumping sewage to a pressurized sewer main. These pumps use a rotating impeller that works on a combination of water pressure and suction to pump the sewage out of your home.

    • Grinder pumps are always sewage pumps.
    • They are more powerful than standard sewage pumps.
    • Though they are more powerful, they are still able to break down solids.
    • It is important to only flush items that belong in a toilet in the first place.
    • They are very useful for keeping restaurants, hotels, and hospitals clean.
    • They are a great choice for low-cost water treatment.
    • They can handle very hard substances like hair and grease.
    • You do not have to replace them as often as other pumps (about every 3-5 years).
    • They are more expensive than standard pumps… but… only if you connect them to multiple toilets. If they are used in isolation, they are less expensive.


  •  Sewage pumps are generally less expensive than grinder pumps.
  • The sewage pumps are not able to move sewage to as high of a point as a grinder pump can.
  • Grinder pumps are often used to move sewage uphill into the sewer lines, while the sewage pumps are used to remove sewage from basements, etc.
  • Grinder pumps are typically more powerful than other sewage pumps, but they are also more expensive
  • A grinder pump will last longer than a general sewage pump.
  • Grinder pumps only work at low flow rates but sewage ejector pumps only work at high flow rates.
  • Grinder pumps are loud. They have a distinctive “churning” sound. On the other hand, ejector pumps are quiet. They don’t make much noise at all.
  • A grinder pump is good for short-range pumping, like up to 500 feet. An ejector pump is best for long-range pumping, like 1,000 feet or more.
  • A grinder pump is the least efficient type of pump for sewage pumping. Sewage ejector pumps are the most efficient type of pump for sewage pumping.

The differences between Sewage Ejector Pump and Septic Grinder Pump was well received on

In conclusion, before you make your final decision on what kind of pump you need for your home’s sewage pumping needs, you have to know the exact capacity that you need to meet. You also need to know how far the sewage has to travel before it gets to your destination. You should know that a lot of homes have gravity sewers that are connected to the city sewer system, but many others have to pump sewage to a pressurized sewer main. If you are going to a pressurized sewer main, then you should be sure that you have a grinder pump.

Both types of pumps work fine for home use. Choose the one you are most comfortable with.
