Below-Grade Plumbing Done Right

Keep Lower-Level Drainage Flowing

When a fixture sits below the main sewer line. Like a basement bathroom or laundry room. Gravity alone won’t move wastewater out. A sewage ejector pump (also called a sewer ejector pump) collects the waste in a sealed basin and pumps it up to the main drain.

When installed and maintained correctly, ejector systems keep your home running smoothly and prevent the kind of backups that turn into emergencies. When they fail, you usually notice. Fast.

We handle sewage ejector pump installation from the ground up. We size pumps and basins properly, install sealed systems with the right check valves and venting, and test cycles thoroughly before we leave. We fit trusted brands like Zoeller and provide upfront estimates before any work starts, so you know the cost going in.

Frequently Asked Questions

What does a sewer ejector pump do?

It pumps waste from below-grade fixtures. A basement bathroom, laundry, or kitchen. Up to the main sewer line when gravity drainage isn’t possible.

How is it different from a sump pump?

A sump pump moves clean groundwater away from your foundation. An ejector pump moves sewage and wastewater. They’re built differently and are not interchangeable.

What are the signs my ejector pump is failing?

Sewage odors, slow or backing-up basement drains, constant running, or a triggered alarm. These point to a worn pump or a stuck float switch.

How long do ejector pumps last?

Typically 7 to 10 years. If yours is near that age and showing symptoms, replacing it on your schedule beats an emergency backup.

Do you offer emergency replacement?

Yes. A failed ejector pump can back sewage into your basement, so call (410) 242-3111 right away. We also inspect the connected sewer line while we’re there.
