- The most common cause for sump pump failure is an electrical power outage.
- Prevent this by having a back-up generator that can be manually activated. Also, protect a potential power surge with a service entrance surge protection device.
The Sump Pump is the wrong size
- Incorrect sized pump will likely cause a failure.
- Too big – pump works too hard and shortens the lifespan, too small – same problem.
- Always follow the manufacturer’s instructions exactly. Read all the do’s and don’ts of installing a sump pump.
Lack of Maintenance
- Check your manufacturer recommendations.
Frozen or Clogged Discharge Lines
- Keep the discharge pipe protected from freezing and free of any kind of debris.
- There is a special grated discharge line attachment that can be added to help prevent this.
- Always test after installation to make sure the sump pump is working properly.
- Your sump pump relies on both he switch and float arm to work properly.
