Common reasons for sump pump failure include:
1. **Power Failure**: Sump pumps rely on electricity, and during storms, power outages can render them inoperative. A backup power source, like a battery or generator, is essential.
2. **Switch Problems**: The float switch, which activates the pump, can become stuck or tangled, preventing the pump from turning on or off. This is often due to debris or improper installation.
3. **Clogged Discharge Lines**: The discharge line can become clogged with debris, ice, or sediment, preventing water from being expelled. This can cause the pump to overheat or fail.
4. **Improper Installation**: Incorrect installation can lead to operational issues. This includes improper sizing, incorrect positioning, or inadequate sealing, which can cause the pump to work inefficiently or fail.
5. **Lack of Maintenance**: Regular maintenance is crucial. Without it, components can wear out, debris can accumulate, and the pump can become less effective over time.
6. **Old Age**: Sump pumps have a limited lifespan, typically around 7-10 years. As they age, their efficiency decreases, and the likelihood of failure increases.
7. **Overwhelmed Pump**: A pump that is too small for the volume of water it needs to handle can become overwhelmed, leading to failure. This is common during heavy rainfalls or flooding.
8. **Frozen or Clogged Intake**: The intake can freeze or become clogged with debris, preventing water from entering the pump, which can cause it to overheat and fail.
9. **Defective Product**: Manufacturing defects can lead to premature failure. It's important to choose a reliable brand and model.
10. **Check Valve Failure**: A faulty check valve can cause water to flow back into the sump pit, forcing the pump to work harder and potentially leading to burnout.
