Understanding the Source of the Smell

When dealing with unpleasant odors from your sewage ejector pump system, it’s essential to understand their potential source. Identifying these causes can lead to effective solutions and long-term maintenance.

Possible Causes

1. Build-up of Waste or Sludge Inside the Ejector Pit

Over time, organic material and waste can accumulate inside the ejector pit, leading to the development of strong, foul odors.

2. Dried-Out Vent or Broken Venting System

A malfunctioning or dried-out vent can prevent odors from being directed outside, causing them to seep indoors instead.

3. Improperly Sealed Lid or Gaskets

If the lid or gaskets are not correctly sealed, odors can escape from the pump area into your home.

4. Cracks or Leaks in the Basin

Small cracks or leaks in the basin may allow sewage and odors to escape, contributing to persistent smells.

Symptoms to Identify

To pinpoint the issue, look for these signs:

• Persistent or recurring foul odors in areas near the pump.
• Gurgling sounds or slow drainage in sinks or toilets connected to the system.
• Visible waste or residue around the ejector pit lid or the surrounding area.

Identifying these causes and symptoms is the first step toward effectively tackling and preventing sewage ejector pump odors.

Safety Precautions Before Cleaning

Before attempting to clean a sewage ejector pump, it is crucial to follow proper safety precautions to avoid accidents and health risks.

Shut Off Power 

Begin by turning off the power to the pump at the circuit breaker. This step is essential to prevent electrical shocks or other hazards during the cleaning process.

Ventilate the Area 

Ensure the space is well-ventilated by opening windows and doors. If possible, use fans to help circulate fresh air and reduce the presence of unpleasant odors or potentially harmful fumes.

Wear Protective Gear 

Always wear protective gear, including gloves, eye protection, and a mask. These items provide a barrier against exposure to raw sewage, harmful bacteria, and strong fumes.

Avoid Using Strong Acids or Bleach Together 

Refrain from using strong acids or mixing bleach with other cleaning agents, as these combinations can release toxic fumes that pose serious health risks. Always adhere to safe cleaning practices.

How to Get Rid of Smell From Sewage Ejector Pump: Cleaning and Deodorizing 

Step 1: Remove the Lid 

Begin by carefully unscrewing or unclamping the lid of the pump basin. Take a moment to inspect the seal for any signs of wear or damage, such as cracks or deformation, as these could lead to leaks or odors. Replace the seal if necessary before reassembling the basin later. 

Step 2: Clean Inside the Basin 

Using a wet/dry shop vacuum, remove any debris, sediment, or other materials from inside the basin. This step helps prevent clogs and ensures the pump operates properly. After vacuuming, use a long-handled brush along with a safe cleaning solution, such as an enzyme-based cleaner or a mixture of vinegar and baking soda, to scrub the inner walls thoroughly. These solutions are effective at breaking down grime and neutralizing odors without introducing harmful chemicals. 

Step 3: Disinfect 

Next, prepare a diluted bleach solution by mixing 1 part bleach with 10 parts water. Use this solution to disinfect the surfaces of the pump basin, focusing on areas that may harbor bacteria or mold. Take care to rinse thoroughly afterward to ensure no bleach residue remains, as it could corrode components or cause strong odors. 

Step 4: Deodorize 

To help control odors over time, sprinkle a generous amount of baking soda inside the basin after cleaning and disinfecting. Alternatively, add a few drops of your favorite essential oil for a fresh scent. These steps will help maintain a pleasant and odor-free environment around the pump basin while keeping it clean and functional. 

Inspecting and Replacing the Seal or Lid 

Proper maintenance of the seal or lid on your pump basin is crucial for ensuring optimal performance and preventing unwanted odors from escaping. 

Check the Lid Seal 

Over time, the rubber gasket that lines the lid can wear down, crack, or entirely degrade. Inspect the seal regularly for signs of damage or wear. If the rubber gasket is cracked, brittle, or missing, it’s essential to replace it promptly to maintain an airtight fit and prevent leaks or odors from escaping. 

Tighten or Replace Lid Bolts 

A loose lid can compromise the functionality of the pump basin by allowing odors or moisture to escape. Check the lid bolts regularly to ensure they are secure. If any bolts are damaged, rusted, or missing, replace them immediately to restore a tight seal. Regular tightening can also help prevent long-term issues with the lid. 

Upgrade to Airtight Lids 

If you’re dealing with persistent odor issues or an aging lid assembly, consider upgrading to a newer, airtight lid model. Modern lids often feature advanced odor-sealing technology and durable materials, designed to provide a longer-lasting solution. This investment can enhance the overall efficiency and cleanliness of your pump system. 

Checking the Ventilation System 

How the Venting Works 

The pump system is typically vented through the roof, allowing gases to escape safely from the system. This ventilation is crucial for maintaining proper airflow and preventing pressure build-up, which could lead to odors or operational issues.

Common Issues 

One of the most frequent problems with venting systems is a clogged vent pipe, which can trap gases and cause unpleasant odors to linger. Another issue may be incorrect installation, where the ventilation system fails to function as intended, disrupting the proper escape of gases.

How to Inspect 

To ensure the ventilation system is clear, use a plumber’s snake to check for blockages in the vent pipe. If you are unable to inspect it yourself or suspect a more complex issue, it is recommended to call a professional plumber to avoid causing further damage.

Add a Charcoal Filter 

For pump systems that accommodate it, consider installing a charcoal vent filter. These filters are designed to neutralize odors effectively by absorbing unpleasant gases as they escape, leading to a fresher and more efficient system overall. Regular maintenance of the filter will ensure its continued performance and benefit to your setup. 

Maintenance Tips to Prevent Future Odors 

Maintaining your pump system is essential to prevent future odors and ensure optimal performance. Following these simple tips can save you time and avoid costly repairs in the long run. 

Monthly or Quarterly Cleaning 

Use enzyme-based cleaners monthly to break down waste and organic matter within your pump system. These cleaners are safe for the environment and work to maintain a healthy balance of bacteria that aids in decomposition. Regular cleaning helps prevent the buildup of debris that can lead to unpleasant smells. 

Run the Pump Periodically 

If your pump system is not used frequently, it’s crucial to run water through the system periodically. This practice keeps the seals moist, preventing them from drying out and allowing odors to escape. A properly maintained flow ensures the system remains efficient even during periods of low use. 

Avoid Dumping Harsh Chemicals 

Harsh chemicals, such as bleach or industrial solvents, can damage the internal components of the pump system and kill the beneficial bacteria that help break down waste. Always opt for milder alternatives and avoid chemical dumping to keep your system running smoothly and odor-free. 

Professional Servicing 

Schedule annual inspections or clean-outs with a licensed plumber to ensure your pump system is in good condition. A professional can identify potential issues early and perform thorough maintenance, ensuring your system operates efficiently while preventing foul odors from developing over time. 

By adhering to these maintenance tips, you can enjoy a fresher and more effective pump system, saving yourself from future hassles. 

Conclusion 

Buildup, inadequate seals, or issues with venting often cause foul odors from a sewage ejector pump. However, with regular maintenance, such as cleaning, inspecting seals, and ensuring proper ventilation, these unpleasant smells can be effectively managed. Remember to schedule professional inspections annually to catch and resolve potential problems early.

If you’re still wondering how to get rid of smell from sewage ejector pump after cleaning and resealing, it’s best to consult a licensed plumber who can check for deeper or hidden issues. Taking these steps will help keep your pump system efficient and your home odor-free.
