This section will help you clarify when a sewage pump is necessary and differentiate it from other types of pumps, ensuring you make an informed decision.

Identifying the Need for a Sewage Pump

A sewage pump, also known as an ejector pump, is specifically designed to handle solid waste and wastewater. It’s not a universal solution for all water-related issues.

The most common scenarios where a sewage pump becomes essential include:

• Basement Bathrooms and Plumbing Fixtures: If you’re adding a bathroom, laundry room, or any plumbing fixture in a basement or area below the level of the main sewer line, gravity alone cannot carry the wastewater to the sewer. A sewage pump is necessary to lift the waste upwards to connect to the main line.

• Uphill Sewer Line Connections: In situations where your home’s sewer line has to travel uphill to connect to the municipal sewer system or septic tank, a sewage pump provides the necessary force to overcome the elevation difference.

• Homes Below the Main Sewer Line: If your property sits at a lower elevation than the municipal sewer line, wastewater cannot flow naturally. A sewage pump is essential to elevate the waste to the appropriate level.

Sewage Pump vs. Sump Pump: Knowing the Difference

It’s easy to confuse a sewage pump with a sump pump, but their functions are fundamentally different.

A sump pump is designed to remove groundwater that accumulates around the foundation of a building, preventing flooding. It handles relatively clean water and isn’t equipped to process solid waste.

A sewage pump, on the other hand, is built to handle raw sewage, including solid materials. Its impeller and motor are designed to grind and pump waste effectively. Using a sump pump for sewage would quickly lead to clogging and failure.

Sewage Pumps and Septic Systems

The relationship between a sewage pump and a septic tank is crucial to understand.

In some septic systems, a sewage pump might be needed to move wastewater from the house to the septic tank, especially if the tank is located uphill or at a distance.

More commonly, a sewage pump is used after the septic tank to pump effluent to a leach field or drain field that is at a higher elevation than the tank. This is particularly common in areas with challenging topography.

If your home utilizes a septic system, consider the layout and elevation differences to determine if a sewage pump is required either before or after the tank. A professional septic system installer or plumber can help assess your specific needs.

Preparing for the Installation: Essential Steps Before You Begin
