sewege ejector

June 20, 2026

A sewage ejector pump is an essential plumbing system for homes with bathrooms, laundry rooms, or other plumbing fixtures located below the main sewer line. Townhouse Plumbing provides professional sewage ejector pump installation, replacement, and repair services throughout Barrie, Richmond Hill, and the GTA. Whether your existing pump has failed or you’re adding a new basement bathroom, our experienced plumbers can install the right system for your home.

What Is a Sewage Ejector Pump?

A sewage ejector pump is designed to move wastewater and sewage from plumbing fixtures located below the main sewer line up to the municipal sewer system or septic tank.

Without a sewage ejector pump, wastewater from basement plumbing fixtures would not be able to drain properly by gravity.

How a Sewage Ejector Pump Works

A sewage ejector system operates automatically through several stages.

1. Wastewater Collection

Wastewater from plumbing fixtures such as:

  • Toilets
  • Bathroom sinks
  • Showers
  • Bathtubs
  • Laundry tubs
  • Floor drains

flows into a sealed sewage basin installed below the basement floor.

2. Automatic Pump Activation

As the wastewater level rises inside the basin, a float switch automatically activates the sewage ejector pump.

3. Pumping the Wastewater

The pump forces wastewater through a discharge pipe and lifts it to the home’s main sewer line or septic system.

4. Backflow Protection

A check valve installed on the discharge line prevents wastewater from flowing back into the sewage basin after the pump shuts off.

Types of Sewage Pumps

Sewage Ejector Pumps

Standard sewage ejector pumps move wastewater and solid waste through larger diameter discharge pipes without grinding the material.

Grinder Pumps

Grinder pumps include internal cutting blades that grind solid waste into a slurry before pumping it through smaller discharge pipes.

Benefits of Installing a Sewage Ejector Pump

Installing a sewage ejector pump provides several important advantages:

  • Allows basement bathrooms and laundry rooms.
  • Prevents sewage backups.
  • Protects your home from wastewater flooding.
  • Supports basement renovations.
  • Improves overall plumbing functionality.
  • Provides reliable wastewater removal.

Important Components

A complete sewage ejector system typically includes:

  • Sewage ejector pump.
  • Sealed sewage basin.
  • Float switch.
  • Check valve.
  • Discharge pipe.
  • Vent pipe.
  • Electrical connection.

Sewage Ejector Pump Installation Process

1. Determine the Installation Location

The sewage basin is installed at the lowest point where wastewater naturally drains.

2. Install the Sewage Basin

A sealed basin is installed below the basement floor to collect wastewater.

3. Install the Pump

The sewage ejector pump is placed inside the basin and connected to the discharge piping.

4. Install the Check Valve

A check valve is added to prevent sewage from flowing backward after each pumping cycle.

5. Connect the Vent System

Proper venting is installed to safely release sewer gases and ensure efficient pump operation.

6. Complete Electrical Connections

The pump is connected to a dedicated electrical circuit according to applicable plumbing and electrical codes.

7. Test the System

The completed system is tested to verify:

  • Proper pump operation.
  • Float switch performance.
  • Leak-free piping.
  • Reliable wastewater discharge.

Signs Your Sewage Ejector Pump Needs Repair

Your sewage ejector pump may require service if you notice:

  • Sewage backups.
  • Slow-draining basement fixtures.
  • Pump running continuously.
  • Loud or unusual noises.
  • Foul odours around the basin.
  • Pump failing to activate.
  • Visible leaks around the pump.

Routine maintenance helps maximize the lifespan of your sewage ejector system.

We recommend:

  • Inspecting the float switch.
  • Cleaning the sewage basin.
