Why Sewer Ejector Pumps Can Fail Sooner.
After conducting a thorough investigation into the premature failure of sewer ejector pumps, several key factors have emerged that explain why these pumps might break down sooner than the manufacturer's warranty period:
Improper Installation.
One of the leading causes of early pump failure is improper installation. If the pump is not installed according to the manufacturer’s specifications—such as incorrect pipe sizing, inadequate venting, or poor alignment—this can cause strain on the motor and moving parts, leading to accelerated wear and tear.
Power Surges and Electrical Issues.
Power surges or fluctuations in the electrical supply can damage sensitive components within the pump, such as the motor or control panel. Even if the surge lasts only a second, it can burn out circuits or compromise the motor's efficiency. Without surge protectors or proper grounding, this can lead to premature failure.
Clogs from Improper Materials. Sewer ejector pumps are designed to handle waste and certain types of debris, but when improper materials—such as feminine hygiene products, wipes labeled as "flushable," or other non-degradable items—are flushed, they can clog or damage the pump. Over time, these clogs can cause the motor to overwork, leading to an early breakdown.
Lack of Regular Maintenance. Routine maintenance is often overlooked. Failing to check and service the pump periodically can result in small issues going unnoticed until they become larger, irreversible problems. Sediment buildup, worn-out seals, or deteriorating gaskets can all contribute to pump failure, especially in areas with hard water where mineral deposits may accumulate.
Overworking the Pump.
Many sewer ejector pumps are not designed to run continuously. If the pump is overworked due to improper sizing, such as being undersized for the household’s waste output or running too frequently, it can result in overheating and breakdown. Ensuring the pump is appropriate for the expected load is essential for longevity.
Environmental Factors.
Harsh environmental conditions such as excessive moisture, flooding, or extreme temperatures can affect the pump’s lifespan. Excessive moisture can cause corrosion of internal components, while extreme cold or heat can affect the motor and seals. Additionally, if the pump is exposed to corrosive chemicals or gases in the sewage, it can degrade faster than expected.
In most cases, premature failure of sewer ejector pumps can be traced to installation errors, misuse, or lack of maintenance. To ensure a pump reaches its full lifespan, it is critical to follow manufacturer guidelines, perform regular maintenance, and avoid flushing materials that can cause clogs. These preventative measures can help avoid costly repairs and ensure the pump functions efficiently for its intended lifespan.
