Ejector Pump Not Working: Troubleshooting and Solutions

If you’re experiencing issues with your ejector pump, it can be both frustrating and inconvenient. Ejector pumps are essential components in basement waterproofing systems, designed to remove wastewater from areas below the main sewer line. When these pumps fail, the consequences can range from minor inconveniences to severe flooding and damage to your home. This comprehensive guide will explore the reasons behind an ejector pump not working, common symptoms, troubleshooting techniques, and solutions to ensure your pump operates efficiently.

Understanding Ejector Pumps

Before diving into the troubleshooting process, it’s crucial to understand what an ejector pump is and how it operates. An ejector pump is typically used when gravity drainage is not possible. It helps to lift wastewater from a lower elevation to a higher elevation, allowing it to drain into the municipal sewer system or a septic tank.

How Ejector Pumps Work

Ejector pumps utilize a motor-driven impeller to generate the force necessary to move wastewater. The basic components include:

  • Motor: Powers the impeller for pumping action.
  • Float Switch: Automatically turns the pump on and off based on the water level.
  • Check Valve: Prevents backflow of wastewater once it has been pumped out.
  • Discharge Pipe: Channels wastewater away from the pump.

When the wastewater level reaches a certain height, the float switch activates the motor. The impeller then pushes the wastewater up through the discharge pipe, effectively ejecting it.

Identifying Symptoms of a Malfunctioning Ejector Pump

Recognizing issues with your ejector pump early can prevent more severe problems down the line. Here are some key symptoms to look out for:

1. Unusual Noises

If your ejector pump starts making grinding, rattling, or humming noises, it may indicate that the motor is struggling or that debris is obstructing the impeller.

2. Frequent Cycling

If the pump turns on and off repeatedly within a short amount of time, it may be overworking due to a faulty float switch or a clog in the discharge line.

3. Foul Odors

A pungent smell around the ejector pit may suggest a buildup of waste, which could signify that the pump is not functioning properly.

4. Water Accumulation

The most evident sign of an ejector pump failure is visible water pooling in the basement or the sump pit. This occurrence indicates that wastewater is not being removed as it should be.
