What Causes a Sump Pump to Fail?

Even the most reliable sump pumps can fail under pressure—especially during severe storms or rapid snowmelt. Here are the most common causes of failure:

• Power Outages. Many sump pumps are electric, which means a power outage during a storm can disable the system when you need it most. That’s why battery backup systems or water-powered backups are recommended.
• Clogged or Frozen Discharge Pipe. If the discharge pipe becomes blocked by debris, ice, or sediment, water can’t exit the system—leading to an overflow. Snowmelt and freezing temps in Central NY make this a genuine concern.
• Stuck or Faulty Float Switch. The float switch activates the pump when water reaches a certain level. If the switch gets stuck or wears out, the pump may never turn on.
• Pump Burnout or Age. Sump pumps typically last 7-10 years. As they age, motor failure becomes more likely, especially if the pump runs frequently or was not correctly sized for your needs.
• Improper Installation. Poorly installed sump pumps—whether set on debris, with improper piping, or without a check valve—are more prone to malfunction.

Signs Your Sump Pump Needs Maintenance

Don’t wait until you’re ankle-deep in water to discover a problem. Look for these early warning signs that your sump pump is failing:

• Unusual noises like grinding, rattling, or humming
• Pump running constantly, even in dry weather
• Water pooling in the sump pit, but the pump doesn’t activate
• Musty basement odors, which can signal mold or mildew from previous leaks
• Visible rust or corrosion on the pump
• Frequent cycling on and off, which can burn out the motor

If you notice any of these symptoms, call in a professional for an inspection. Green Tree Environmental offers expert help with sump pump failure and water damage restoration in Central NY.

How to Prevent Sump Pump Failures

Prevention is the key to avoiding water damage and expensive repairs. Here’s how to protect your sump pump system:

• Schedule Annual Maintenance. Have your sump pump tested and cleaned at least once a year. This includes checking the float switch, discharge line, and motor.
• Test Your Pump Regularly. Every 3 months, pour a bucket of water into the sump pit to ensure the float rises, the pump activates, and water is discharged properly.
• Clear Debris from the Pit and Pipe. Remove any leaves, sediment, or debris from the pit and check the discharge line for blockages.
• Install a Backup Power Source. Battery or water-powered backups ensure your sump pump can function during a power outage—especially critical in storm-prone areas like Central New York.
• Add a High-Water Alarm. Alarms notify you when water levels rise too high, giving you time to act before flooding occurs.

Pro Tip: Always test your pump before storm season in Central New York.
