If you’re a homeowner, you understand how important it is to maintain a healthy and dry living space. One way to accomplish this is by installing a pump system to prevent flooding and pump out harmful sewage. However, there are two commonly mistaken pump systems that many homeowners confuse with one another: the sump pump and the ejector pump.
Although both pumps are designed to keep your home free from water damage and harmful sewage, they serve different purposes. A sump pump is typically used to pump out excess water that accumulates in the sump pit under your basement. On the other hand, an ejector pump is used to pump out sewage from your basement that cannot be pumped out by gravity alone. These two pumps have distinct differences that homeowners should be aware of in order to properly maintain their homes.
Understanding the differences between a sump pump and an ejector pump is key to making the right choice for your home. If you choose the wrong pump system, your home may not be properly protected from water damage or sewage backup. In this article, we’ll dive deeper into the differences between these two pump systems and help homeowners make an informed decision that will keep their living spaces safe and dry. So, let’s take a closer look at the sump pump versus the ejector pump and see which one is the right fit for your home.
Sump Pump vs. Ejector Pump
Both Sump pumps and Ejector pumps serve as a crucial part of your home’s waste management system, but they have significant differences that should be taken into consideration when selecting which type of pump is most suitable for your needs.
What is a Sump Pump?
- A sump pump is used to remove water from the basement or crawl space of your home
- The pump is placed in a sump pit that collects water that drains into the basement
- These pumps are typically used to prevent flooding during heavy rain, or to pump out water that may seep into the basement walls or floor
- There are two primary types of sump pumps: submersible and pedestal pumps
What is an Ejector Pump?
An ejector pump, also called a sewage pump, is designed to move raw sewage from your home to the sewage system located within your property. These pumps are also commonly used for septic tank systems when homes are not connected to a public sewage system.
Ejector pumps come with two types of impellers, single-vanes, and multi-vanes. Single-vane impellers are less expensive and more efficient for pumping fluids with solids. On the other hand, multi-vane impellers are more expensive and better suited to fluids without solids.
Differences Between Sump and Ejector Pump
| Features | Sump Pump | Ejector Pump |
|---|---|---|
| Usage | Removes water from the basement or crawl space | Pumps sewage from a home to the sewage system |
| Installation | Easy to install | Requires experienced professionals for installation |
| Design | Designed to pump water and other fluids with solids | Designed to pump raw sewage and other fluids without solids |
| Cost | Less expensive than ejector pumps | Ejector pumps are more expensive |
Ultimately, when deciding between a sump pump and an ejector pump, it is essential to consider the primary purpose of the pump and the type of fluid it will be required to pump. If you’re unsure about which type of pump is right for your home, seek the advice of a professional plumber or technician.
Working Mechanism
Both sump pumps and ejector pumps are used to combat unwanted water in a basement or lower level of a building. However, their working mechanisms differ.
- Sump Pump: A sump pump is typically used in a basement or crawlspace to remove excess water that has collected in a sump pit. The pump is activated when the water reaches a certain level in the pit, triggering a switch that turns on the pump. The pump then sucks up the water and expels it through a discharge pipe, typically outside the building or into a designated drainage area.
- Ejector Pump: An ejector pump, on the other hand, is used to remove sewage and wastewater from a basement or lower level bathroom or laundry room. The pump is typically located in a pit or basin below the level of the main sewer line. When waste water from the toilet or sink drains down into the pit, the ejector pump is activated. The pump then grinds up the solid waste and expels it through a discharge pipe that is connected to the sewer line or septic tank.
Overall, while both sump pumps and ejector pumps serve important functions in keeping a building dry and clean, their working mechanisms are different and serve different purposes.
Capacity
The capacity of a pump refers to the amount of water it can handle in a given amount of time. Sump pumps and ejector pumps have different capacities because they are designed to handle different types of water and wastewater.
- A sump pump can typically handle up to 60 gallons of water per minute, making it ideal for removing moderate to heavy amounts of groundwater from a basement or crawlspace.
- An ejector pump, on the other hand, can handle much higher volumes of water and wastewater, ranging from 100 to 400 gallons per minute or more. This makes it ideal for pumping sewage and other types of wastewater from a lower level to an elevated discharge point, such as a sewer main or septic field.
- The capacity of a pump can also vary depending on the horsepower of the motor, which determines the speed and efficiency of the pump’s impeller. Higher horsepower pumps can handle larger volumes of water and wastewater, but they may also be more expensive and consume more energy.
To determine which type of pump is best for your needs, it is important to consider the specific volume and type of water or wastewater that needs to be pumped, as well as the depth and distance it needs to be moved. Consulting with a professional plumber or pump installer can also help ensure that you choose the right pump for your specific application.
| Pump Type | Capacity (GPM) | Horsepower (HP) |
|---|---|---|
| Sump Pump | Up to 60 | 1/3 – 1 |
| Ejector Pump | 100 – 400+ | 1/2 – 5 |
It is important to note that the specifications and capacities of pumps can vary depending on the manufacturer and model, so it is always best to consult the product literature or seek professional advice before making a purchase.
Installation Process
Both sump pumps and ejector pumps have different installation processes, which may impact the cost and efficiency of your system. Here’s a breakdown of what you need to know:
- Sump Pump: The installation process for a sump pump involves cutting a hole in your basement floor, excavating a basin, placing a liner inside the basin, putting in gravel for drainage, installing the pump itself, and adding piping for the water to exit the home. This process can be extensive and may require the help of a professional plumber or contractor.
- Ejector Pump: The installation process for an ejector pump involves creating a separate waste system in your basement, adding a basin and liner, installing the pump and piping, and adding venting for odor control. This process requires more extensive plumbing work than a sump pump and is typically more expensive to install.
Both sump and ejector pumps require a reliable source of power, so it’s crucial to ensure that your pump is plugged into an outlet that is separate from any other electrical devices or appliances.
If you’re unsure which type of pump is best for your home, it’s always better to consult with a professional plumber or contractor. They can assess your home’s needs and recommend a system that will efficiently and effectively protect your home from water damage.
Common Installation Mistake
A common mistake homeowners make when installing a sump pump or ejector pump is failing to properly maintain the system. It’s essential to regularly inspect your pump, check for blockages, and perform routine maintenance to ensure your pump is functioning correctly. Failure to do so can lead to costly repairs and even render your pump useless.
Sump Pump vs. Ejector Pump Installation Costs
The installation costs for a sump pump and ejector pump can vary depending on several factors. A professional installation for a sump pump can range from $600 to $3500, while an ejector pump installation can cost anywhere from $1500 to $5500. The cost will increase if there are any issues with the drainage system or pipes in your home that need to be fixed before installation.
