A sump pump is an essential device for homes located in areas with high water tables or prone to flooding. It helps keep basements dry by pumping out accumulated water from the sump pit and directing it away from your home. But what if your sump pump keeps running even when there’s no rain or visible flooding? Understanding the causes can help prevent damage to your home and costly repairs. In this post, we’ll explain some common reasons why your sump pump may be running continuously and why seeking professional services is crucial.
Common Reasons Your Sump Pump Won’t Stop Running
- Stuck or Faulty Float Switch
The float switch is a critical component of your sump pump that detects the water level in the sump pit. When water rises, the float switch activates the pump to remove the excess water. However, if the float switch is stuck in the “on” position or has failed, it can cause your pump to run continuously, even when the water level is low. Debris or sediment buildup in the sump pit can cause the float to get stuck. In some cases, the switch itself may be damaged or worn out, requiring professional replacement.
- High Groundwater Levels
If you live in an area with a high water table or your home has experienced prolonged rainfall, the sump pump may need to run more frequently to keep up with the water accumulation. Continuous running during or immediately after a heavy rainstorm is normal. However, if the pump continues to run long after the weather has cleared, this may indicate that your groundwater levels are persistently high. In such cases, it’s essential to have a professional assess whether your pump is sized appropriately to handle the volume of water.
- Improper Sump Pump Size
An undersized sump pump may struggle to handle large volumes of water, leading it to run for extended periods. Alternatively, if your sump pump is oversized, it may activate and deactivate too frequently, causing wear and tear on the motor. A professional plumber can help determine if your sump pump is the right size for your home and install a properly sized unit if necessary.

- Clogged or Frozen Discharge Pipe
A clogged or frozen discharge pipe prevents water from being pumped away from your home, causing the sump pump to run continuously without effectively removing the water. In cold weather, ice can form inside the discharge pipe, leading to a blockage. Debris, such as leaves or sediment, can also obstruct the pipe, requiring cleaning or repairs. Installing a sump pump discharge line protector or an insulation system can help prevent clogs and freezing. If you suspect your discharge pipe is blocked, it’s best to call a professional plumber to inspect and clear the line. Find additional tips on discharge pipe maintenance here.
- Check Valve Failure
The check valve is a one-way valve that prevents water from flowing back into the sump pit once it’s been pumped out. If the check valve fails or is missing, water can return to the sump pit, forcing the sump pump to work overtime and run continuously. A properly installed check valve ensures that water moves in one direction—away from your home. If your sump pump is frequently cycling, it’s time to have a professional inspect the check valve and replace it if necessary.
- Electrical Issues
Sometimes, electrical problems can cause your sump pump to run continuously. Wiring issues, faulty control boards, or malfunctioning circuits can all lead to a constantly running pump. Electrical issues with sump pumps can be complex and dangerous, so it’s best to leave troubleshooting and repairs to a qualified professional.
When to Call a Professional Plumber
While some sump pump issues can be addressed with basic maintenance, others require professional intervention. If you notice that your sump pump is running constantly without a clear reason, it’s essential to seek expert help to prevent serious damage to your pump or home. Delaying repairs can result in motor burnout, flooding, and expensive water damage.
Here are some signs that it’s time to call a professional plumber:
- Your sump pump runs constantly, even when the weather is dry.
- There’s an unusual noise or vibration coming from the pump.
- The sump pit is dry, but the pump continues to run.
- You’ve noticed water pooling around your foundation despite the sump pump’s operation.
- The float switch is stuck, and you’re unable to resolve the issue on your own.
Preventative Measures for Sump Pump Health
To ensure your sump pump runs efficiently, regular maintenance is essential. Here are some ways to keep your sump pump in optimal working condition:
- Regular Cleaning: Clear any debris, dirt, or sediment from the sump pit to prevent the float switch from sticking and the pump from clogging.
- Test Your Pump: Periodically pour water into the sump pit to ensure the pump activates and removes the water as it should.
- Check the Discharge Pipe: Inspect the discharge line to make sure it’s free from obstructions and properly draining water away from your home.
- Professional Inspections: Schedule regular inspections with a licensed plumber to check for worn parts, electrical issues, or other problems that could prevent your sump pump from working efficiently.
