Whether you are a homeowner, business owner, or simply interested in understanding how sewage systems work, this article will provide you with all the information you need. From what a sewage ejector pump is to how it operates and the importance of regular maintenance, we’ve got you covered.

What is a Sewage Ejector Pump?

Before we get into the specifics, let’s start with the basics. A sewage ejector pump, also known as a sewage grinder pump, is a crucial component of many sewage systems in Chicago. Its primary purpose is to remove wastewater from lower levels of a building and pump it uphill to the main sewer line.

Unlike a regular sump pump that deals with just water, a sewage ejector pump is designed to handle solid waste, including toilet paper, human waste, and other debris that enters the sewage system. With powerful grinding blades, these pumps macerate the waste, ensuring smooth flow through the sewer pipes.

Now that we have a basic understanding of what a sewage ejector pump is, let’s explore its operation and why it’s essential for many properties in the Chicago area.

How Does a Sewage Ejector Pump Work?

A sewage ejector pump is typically installed in the basement or lower levels of a building. It is connected to a basin, also known as a sewage pit or a sump pit, where wastewater collects. When the wastewater reaches a certain level, the pump’s sensors are triggered, activating the pump.

The pump’s impeller, a rotating device with blades, starts spinning rapidly, creating a powerful centrifugal force. This force enables the pump to macerate the solid waste into smaller pieces, making it easier to pump through the sewer pipes.

As the waste is macerated, the sewage ejector pump forces it through a discharge pipe connected to the main sewer line. The pump continues to operate until the water level in the sewage pit lowers, at which point it shuts off automatically.

The Importance of Sewage Ejector Pumps in Chicago

Chicago is home to countless residential and commercial properties. Many of these properties are equipped with sewage ejector pumps to overcome challenges posed by the city’s unique topography.

Due to its flat geography, Chicago relies on sewage ejector pumps to transport wastewater from lower-lying areas to the city’s sewer system, which lies at a higher elevation. Without these pumps, it would be impossible to efficiently drain wastewater from basements and lower-floor bathrooms or kitchens.

By effectively macerating and pumping solid waste, sewage ejector pumps minimize the risk of sewer backups, sewage overflows, and related issues that can cause significant damage to properties and pose health hazards.

Additionally, sewage ejector pumps are essential in areas where septic systems are in use. These pumps help lift effluent from septic tanks to sewer lines, ensuring proper disposal and preventing contamination of groundwater sources.

Periodically clean the sump pit to remove any debris or sediment that may accumulate. This will prevent clogs and promote smooth pump operation.

Sewage Ejector Pump Maintenance

Regular maintenance is key to ensuring the optimal performance and longevity of your sewage ejector pump. By following these maintenance tips, you can prevent potential issues and avoid costly repairs in the future:

1. Ejector Pit Cleaning

Periodically clean the sump pit to remove any debris or sediment that may accumulate. This will prevent clogs and promote smooth pump operation.

2. Check the Float Switch

Make sure the float switch is free of obstructions and moves freely. The float switch is responsible for activating the pump when the water level rises.

3. Test the Pump

Regularly test the pump by pouring water into the sump pit until the float switch activates. This will help identify any issues before they escalate.

4. Inspect the Discharge Pipe

Check the discharge pipe for any signs of leaks, cracks, or blockages. A damaged pipe can lead to reduced pump performance and potential sewage backups.

5. Professional Inspections

Consider scheduling professional inspections of your sewage ejector pump system annually. A qualified Chicago plumber can identify and address any underlying issues.

Decide whether you prefer an electric-powered pump or one that operates on a backup battery system. Electric pumps are reliable but may need a generator during power outages.

Choosing the Right Sewage Ejector Pump

When it comes to selecting a sewage ejector pump for your property in Chicago, there are a few factors to consider:

1. Pump Capacity

Determine the average daily wastewater flow rate in your property to choose a sewage ejector pump with sufficient capacity. A pump with inadequate capacity can lead to pump failure and backups.

2. Power Source

Decide whether you prefer an electric-powered pump or one that operates on a backup battery system. Electric pumps are reliable but may need a generator during power outages.

3. Brand Reputation

Research different brands and models to find reliable and reputable manufacturers. Look for models with positive reviews and a proven track record.

4. Qualified Installation

Ensure your sewage ejector pump is installed by a qualified professional to guarantee proper functioning and compliance with local building codes.

Sewage ejector pumps play a vital role in Chicago’s sewage systems, allowing properties to efficiently remove wastewater from lower levels and preventing backups and overflows. By understanding how sewage ejector pumps work, the importance of maintenance, and the factors to consider when choosing a pump, you can ensure the optimal performance of your system.

If you are in Chicago and require assistance with your sewage ejector pump, don’t hesitate to contact a professional plumber specializing in flood control systems. With their expertise, you can keep your sewage system in top condition and enjoy a clean and functional property.

Remember, regular maintenance and prompt repairs are critical to avoiding costly damage and maintaining a safe environment for you and your community.

What is an ejector pump? Is it the same thing as a sump pump? If I already have a sump pump in my home, do I need to install an ejector pump too? These are a few of the questions homeowners ask about ejector pumps, and in this post, we answer all of them.

What is an ejector pump?

An ejector pump is a compact appliance used to pump wastewater from a home’s drains into the main sewer line. Keyrenter Oklahoma City team explains, it is a sewage pump system designed to collect wastewater from below-grade drains and lift it to where it easily flows into the sewer. Ejector pumps can collect wastewater only or a combination of wastewater and sewer water.

How does an ejector pump Work?

The operation of an ejector pump is simple. Firstly, water from below-grade plumbing fixtures in the home drains into a sealed underground pit in the basement. Discharge pipes from the fixtures slope into the sides of the basin, allowing their content to easily slide into the pit. This waste is then moved to a higher elevation by an automatic pump installed inside the pit.

When is an ejector pump needed?

Plumbing systems, from inception, have always relied on gravity to move wastewater from the home to the municipal sewer lines or a septic tank system. But this system only works when wastewater is moving from a high elevation to a low one. In homes where the plumbing fixtures are below-grade level, this system will not work. In such cases, the plumbing needs help to move wastewater from below-grade parts of the home into the sewer line. That is what an ejector pump does.

What’s the Difference between a sump pump and an ejector pump?

Sump pumps and ejector pumps have a lot of things in common but serve completely different functions. Similarities between the two include; both systems being housed in a pit located in the basement or crawlspace; they both help move water from inside the home to the outside, and they do this with the help of automatic pumps. But there are also a lot of vital differences between sump pumps and ejector pumps.

Sump pumps: Sump pumps help to prevent flooding. They handle water coming into the home from the outside. It can be groundwater that infiltrates the basement or runoff that ends up in the basement after flowing over the ground. Water removed by a sump pump is discharged at a point outside the home, in the yard or into a storm sewer.
Ejector pumps: Ejector pumps handle water from plumbing fixtures or water-utilizing appliances inside the home. Unlike sump pumps which are designed to only work during emergencies, ejector pumps are expected to work at intermittent periods throughout the day. Unlike the sump pump where the pit is often open, the lid of the ejector pump is completely sealed.

What are the different types of ejector pumps?

Although there are many different types of ejector pumps, most residential and light commercial pumps can be divided into two major categories: sewage ejector pumps and sewage grinder pumps.

Sewage ejector pumps: These are high-volume/low-pressure submersible pumps that do not have grinding blades. They are designed to handle solids of no more than 2’’ in diameter. They draw sewage into the system through the bottom via a spinning mechanism. Their motors range in size from 4/10 – 2 HP.

Use this type of ejector pump if:

Pumping sewage to a short distance of 750 feet or less.
You have a short vertical distance – under 70 feet – to lift sewage to.
You are pumping to a gravity sewer main.
You are pumping sewage to a septic tank system.

Sewage grinder pumps: These low-volume/high-pressure submersible pumps are designed to handle solids. They have cutting blades that grind raw sewage and reduce it to a slurry. Sewage grinder pumps can pump at pressures of up to 60 P.S.I. Their motors range from 2 HP and over.
