How to Clean and Maintain a Sewage Ejector Pump

A sewage ejector pump is a device that is installed to remove sewage from a location lower than the main sewer line in a building. These pumps are commonly found in basements, as well as in other locations where gravity drainage is not possible. It typically consists of a collection basin, a pump, a discharge pipe, and a check valve.

It's important to keep your sewage ejector pump clean and well-maintained to ensure it functions properly and to avoid any potential problems. Here's a step-by-step guide to help you clean and maintain your sewage ejector pump:

Step 1: Safety Precautions

Before you begin any work on the pump, make sure to take the necessary safety precautions:

- Wear gloves, safety goggles, and sturdy shoes.

- Turn off the power to the pump at the circuit breaker or main electrical panel.

- Ensure that the pump is unplugged and disconnected from the power source.

Step 2: Inspect the Basin

- Open the lid or cover of the pump basin.

- Inspect the basin for any signs of damage, corrosion, or leaks. Look for any cracks or holes in the basin itself, as well as in any pipes or connections.

- Clean the basin by wiping it down with a damp cloth.

Step 3: Remove Debris

- Use a brush or a wet/dry vacuum to remove any debris from the basin. Be sure to clear away any hair, cloth, or other items that may have gotten stuck in the pump.

Step 4: Check the Pump

- Remove the pump from the basin by unscrewing the bolts that hold it in place.

- Inspect the pump for any signs of wear or damage. Look for cracks, corrosion, or damage to the impeller or other components.

- Clean the pump housing and impeller with a damp cloth or a brush.

Step 5: Check the Discharge Pipe

- Inspect the discharge pipe for any blockages or obstructions.

- Ensure that the check valve in the discharge line is functioning properly to prevent backflow.

- Clean the check valve if necessary.

Step 6: Test the Pump

- Reinstall the pump and reconnect the power supply.

- Turn on the power and test the pump by flushing the toilet or running water in the sink connected to the pump.

- Observe the pump to make sure it's working properly and check for any leaks.

Step 7: Replace Parts (if Necessary)

- If you notice any damaged or worn-out parts during your inspection, such as the pump impeller, check valve, or gaskets, replace them with original or compatible parts to ensure optimal performance of the pump.

Step 8: Regular Maintenance

- Perform regular maintenance on your sewage pump every 6-12 months to ensure it continues to operate efficiently and to catch any issues early on. This may include cleaning the basin and pump, checking for leaks, and testing the pump's functionality.

Step 9: Professional Service (if Needed)

- If you encounter any significant problems or if you're uncomfortable performing the maintenance yourself, contact a licensed plumber for assistance.

Remember, it's important to follow the manufacturer's guidelines and recommendations specific to your sewage ejector pump model for proper maintenance. Regular cleaning and maintenance will help extend the lifespan of your pump and prevent costly repairs or replacements.
