7 Common Sewage Pump Problems | How to Prevent or Fix Them

Understanding common sewage pump problems empowers homeowners to identify issues promptly, enabling timely intervention and ensuring the continued functionality of their sewage pump systems. With that in mind, let us check the seven common issues and how to fix them.

1. Clogging Challenges

One of the primary challenges is the accumulation of debris and foreign objects within the sewage pump system. From sanitary products to solid waste, any obstruction can lead to clogs, disrupting the pump’s smooth operation and potentially causing backups in the sewage system.

What you can do: Mindful disposal practices are paramount. Educate household members on responsible waste disposal to prevent items like grease, sanitary products, and non-biodegradable materials from entering your sewage system.

To get rid of clogs, inspect and clear the pump intake. Remove any debris or foreign objects causing the obstruction. If you are not sure about doing it yourself, it is advisable that you enlist professional help to avoid inefficient repairs.

2. Power Failures

Issues related to the electrical components of the pump, such as faulty wiring or motor malfunctions, can result in power failures. Without a stable power supply, the pump fails to function correctly, compromising its ability to efficiently manage wastewater.

What you can do: Promptly check for frayed wires, faulty connections, or any signs of electrical issues. Assess the motor. Reach out to a professional with intense knowledge of sewer systems for help.

3. Float Switch Failures

The float switch, responsible for activating the pump when the sewage reaches a certain level, can experience malfunctions. You may notice erratic pump activation, failure to respond to rising sewage levels, visible damage or misalignment in the float switch, and abnormal pump behaviour. This will affect the overall performance of the sewage pump.

What you can do: Test and, if necessary, replace the float switch. Ensure proper installation and alignment to guarantee accurate activation at the required sewage level. Only rely on a trusted engineer to carry out this delicate step. They understand installation guidelines and are experienced in handling such issues.

4. Overworked Pump Syndrome

Continuous and excessive use of the sewage pump without adequate breaks can strain its components. You will notice increased operating noise, excessive vibration, and decreased pump efficiency.

What you can do: Implement a schedule to avoid continuous and excessive usage. Provide breaks to prevent strain and extend the pump’s lifespan.

5. Faulty Check Valves

Faulty check valves within the sewage pump system can lead to backflow issues. These valves are designed to prevent the reverse flow of sewage, and any malfunction can result in sewage returning to undesired locations within the plumbing. You may hear gurgling or unusual sounds during pump operation, which indicates the check valve is defective.

What you can do: To start with, it is important that you have the check valve inspected on a regular basis. Professionals will be able to identify issues and replace the valve before it leads to system damage.

If your check valve is damaged and you need to replace it, ensure the correct orientation during installation and that the arrow indicates the direction of the flow for optimal functioning.

6. Strange Sounds and Vibrations

Unusual noises and vibrations emanating from the sewage pump are often indicative of underlying mechanical problems. These may include issues with the impeller, motor, or other internal components, signalling a need for prompt attention to prevent further damage.

What you can do: You will need to investigate the source of the noise and act accordingly. This may involve lubricating moving parts or tightening loose components. If it looks too difficult to handle on your own, seek professional assistance promptly to diagnose and resolve the issue.

7. Seal And Gasket Issues

The wear and tear of seals and gaskets over time can compromise the integrity of the sewage pump. Leaks may occur, reducing the pump’s efficiency and potentially leading to water damage in the surrounding area.

What you can do: Visually inspect for wear and damage, promptly replacing any compromised components. Ensure proper installation and use of compatible, high-quality materials. This requires expert assistance, and it is advisable that you avoid DIY tricks.
