How to Fix Ejector Pump

If your home relies on an ejector pump to manage sewage and wastewater, ensuring it functions properly is essential for maintaining a clean and odor-free environment. Ejector pumps are vital components in basement bathrooms, laundry rooms, or any below-grade plumbing systems where gravity drainage isn't possible. When these pumps fail or malfunction, it can lead to backups, unpleasant odors, or costly water damage. Fortunately, many common issues with ejector pumps can be diagnosed and fixed with some basic troubleshooting and maintenance. In this guide, we'll walk you through the steps to identify problems and how to fix your ejector pump effectively.

How to Fix Ejector Pump


Understanding Your Ejector Pump System

Before attempting repairs, it's important to understand how your ejector pump works. An ejector pump is designed to move wastewater from low-lying areas (like a basement bathroom) up to the main sewer line. It typically consists of a pump, a float switch that activates the pump when water reaches a certain level, and a basin or tank that collects the waste.

Common issues with ejector pumps include electrical failures, mechanical wear, clogged inlet or outlet pipes, and float switch malfunctions. Recognizing these problems early can prevent extensive damage and costly repairs.


Step 1: Ensure Safety First

  • Turn off the power to the pump at the circuit breaker to prevent electrical shock.
  • Wear protective gloves and eyewear since you may be dealing with sewage or wastewater.
  • Ensure the area around the pump is dry and safe to work in.

Step 2: Inspect the Ejector Pump and Basin

Begin by examining the pump and its basin for obvious issues:

  • Check for obstructions: Remove any debris, sticks, or objects blocking the inlet or outlet pipes.
  • Inspect for standing water: Excess water may indicate a malfunctioning float switch or a clogged pump.
  • Look for damage or cracks: Examine the pump housing for cracks or corrosion that could cause leaks.

If you notice any physical damage or severe blockages, replacing the damaged parts or the entire pump may be necessary.


Step 3: Test the Float Switch

The float switch activates the pump when water reaches a certain level. If the pump isn't turning on, the float switch could be faulty:

  • Manually lift the float to see if the pump activates. If it does, the switch is working; if not, proceed with further troubleshooting.
  • Check for obstructions around the float that may prevent it from moving freely.
  • Ensure the float switch is securely connected and not damaged.

If the float switch is defective, it may need to be replaced. Many models have replaceable float switches available at hardware stores.


Step 4: Examine Electrical Components

Electrical issues are a common cause of ejector pump failure:

  • Check the circuit breaker to ensure the pump's circuit hasn't tripped.
  • Inspect power cords and connections for damage or corrosion.
  • Test the outlet with another device to confirm power supply.

If electrical components appear intact but the pump still doesn't operate, consider testing the pump motor directly or consulting a professional electrician.


Step 5: Clear Clogs and Blockages

Clogged inlet or outlet pipes can cause the pump to fail or run improperly:

  • Disconnect the pump from power before proceeding.
  • Detach the inlet and outlet pipes carefully.
  • Use a plumbing snake or auger to remove any debris or buildup inside the pipes.
  • Flush the pipes with clean water to ensure they're clear.

Ensure all connections are tight and secure before reassembling.


Step 6: Test the Pump and Reassemble

After completing inspections and cleaning:

  • Reconnect the pump and restore power.
  • Pour clean water into the basin to see if the pump activates at the correct water level.
  • Observe the pump's operation for several cycles to ensure it runs smoothly and shuts off appropriately.

If the pump still doesn't operate correctly, it may be time to replace it or call a professional plumber for further diagnosis.


Additional Tips for Maintaining Your Ejector Pump

  • Regular Inspection: Check the pump and basin monthly for debris, water level, and signs of wear.
  • Clean the Basin: Periodically remove and clean the basin to prevent buildup.
  • Test the Pump: Manually activate the float switch to ensure it triggers the pump.
  • Replace Worn Parts: Replace float switches or impellers showing signs of wear or damage.
  • Professional Maintenance: Schedule annual inspections with a licensed plumber to keep your ejector system in optimal condition.

When to Call a Professional

If you've gone through the troubleshooting steps and your ejector pump still isn't functioning properly, or if you're uncomfortable with DIY repairs, it's best to contact a licensed plumber. Persistent issues like persistent flooding, persistent inability to activate, or electrical problems require professional assessment and repair to ensure safety and proper operation.

Summary of Key Points

Maintaining and repairing your ejector pump doesn't have to be daunting. Start by understanding how the system works and performing routine inspections. Common issues such as float switch failures, clogs, electrical problems, or physical damage can often be fixed with basic troubleshooting. Always prioritize safety by turning off power before working on the pump, and don't hesitate to seek professional help when needed. Regular maintenance will extend the lifespan of your ejector pump and prevent costly plumbing emergencies, ensuring your home remains clean, odor-free, and functional.
