Sump Pump vs. Sewage Ejector Pump: What’s the Difference?

When it comes to keeping your basement dry and your plumbing flowing smoothly, two systems often come into play: sump pumps and sewage ejector pumps. While they may sound similar, they serve very different purposes. Here's a breakdown to help you understand the difference and why it matters.

What Is a Sump Pump?

A sump pump is designed to remove groundwater that collects in a sump pit, usually located in the lowest part of a basement or crawlspace. This pump activates automatically when water levels rise and sends the water away from the home, often through a discharge pipe that leads outside.

Purpose:

Prevent basement flooding

Protect foundation from water damage

Manage high water tables or heavy rains

Common in Homes With:

Basements below the water table

Poor exterior drainage

History of water intrusion

What Is a Sewage Ejector Pump?

A sewage ejector pump is used to pump out wastewater from bathrooms, laundry rooms, or other plumbing fixtures located below the main sewer or septic line. Since gravity alone can’t move waste upward, an ejector pump is installed to push it up into the main sewer system.

Purpose:

Move solid and liquid waste from basement bathrooms or laundry

Prevent sewage backups

Comply with plumbing code in finished basements

Includes a Sealed Pit: Unlike a sump pit, a sewage ejector basin must be sealed to contain odors and gases, and is connected to a vent stack.

If you’re finishing your basement or purchasing a home with plumbing below grade, make sure your system is correctly installed and maintained.

Top 10 Inspection Topics Every Colorado Agent Should Understand

We are always impressed when an agent is able to intelligently communicate inspection findings and knowledge to their client during the inspection process. Having a working knowledge of common inspection issues can help you set expectations, avoid surprises, and win major credibility with clients.

Here are the top 10 home inspection topics every residential agent in Colorado should be familiar with:

🏠 Top 10 Inspection Topics in Colorado

1. Aluminum Wiring
   Common in homes built mid-60s to mid-70s. Is a fire hazard if not properly repaired and is flagged for detailed evaluation and repair.

2. Federal Pacific & Zinsco Panels
   These outdated electrical panels are known to fail under load and are always called out for replacement.

3. High Radon Levels
   Radon is common in Colorado due to our geology. Anything ≥ 4.0 pCi/L is recommended for mitigation.

4. Polybutylene & Galvanized Pipes
   These older plumbing materials are prone to failure and often lead to insurance or resale concerns.

5. Aging HVAC Systems
   Furnaces over 25 years and A/Cs over 15 years are at or near end-of-life. 

6. Asbestos-Containing Materials
   Common in older homes (especially popcorn ceilings, duct wrap and flooring). Asbestos can’t be confirmed visually and testing is required for confirmation.

7. Roof Age & Condition
   Understanding roof hail damage and claims is key in our climate. Knowing what to do with an inspector's findings is key.  Insurance companies often require documentation or inspection.

8. Grading & Drainage Issues
   Poor grading can lead to foundation moisture issues, especially with Benonite clay soils in Colorado.

9. Sewer Line Concerns
   Root intrusion, bellies, and breaks are common. Sewer scopes are highly recommended—even on newer homes.

10. Structural Movement
    Colorado’s expansive Bentonite clay soils can cause foundation shifting or settlement cracks. Minor cracks = common. Major displacement = concern.
