Understanding why your sump pump keeps running is crucial for maintaining a dry and safe basement. Read on to learn more about identifying and addressing the root causes of a sump pump’s continuous activity.
8 Reasons Why Your Sump Pump Keeps Running
Here are some key reasons why your sump pump keeps running. We’ve included images to illustrate each component of a sump pump for clarity.
Stuck Float Switch
The float switch signals the pump to start when the water level rises and stop when it’s lowered. If this switch gets stuck, the pump might not turn off, leading to continuous operation.
Faulty Check Valve
This valve prevents water that has been pumped out from flowing back into the sump pit. A malfunctioning check valve could cause the pump to cycle on and off repeatedly, trying to manage returning water.
Clogged Discharge Line
The line that carries water away from your home can become clogged, preventing water from being expelled. This blockage can cause the pump to struggle to reduce the water level, explaining why it keeps running non-stop.
Improperly Sized Pump
If your sump pump is too small for the area it’s meant to service, it may run constantly to keep up with the water volume, leading to overwork and potential failure.
Continuous Water Inflow
External factors such as heavy rainfall can cause water to flow into the sump pit at a rate that necessitates constant pumping.
Underground Water Leak
A burst pipe from other systems (such as sewer pipes) can lead to water infiltrating the sump pit. This constant influx of water overwhelms the sump pump, forcing it to run continuously.
High Water Table
Homes located near the water table line are at higher risk of persistent water issues. In such cases, the sump pump works non-stop to prevent flooding. Installing a secondary sump pump provides an added layer of protection in these cases.

Broken Impeller
The impeller (a fan-like component in the sump pump) is critical for moving water in and out of the pit. If the impeller becomes broken or clogged, the pump motor will keep running, but no water will flow through the system.

Risks of a Sump Pump That Won’t Turn Off
A sump pump that is always running is a warning signal that shouldn’t be ignored. Continuous operation can lead to several problems, not only for the pump itself but for your home’s safety and your wallet.
Motor Burnout
The most immediate risk of a constantly running sump pump is the wear and tear on the motor. Sump pumps are designed to cycle on and off, not run continuously. Overworking the pump can lead to motor burnout, requiring a costly replacement.
Increased Energy Bills
The longer your sump pump runs, the more electricity it uses. This continuous operation can lead to a noticeable increase in your energy bills, affecting your monthly budget.
Ineffective Water Management
If your sump pump is always running but not effectively managing water levels, it could indicate that the system is overwhelmed or malfunctioning. This situation can lead to water damage or flooding, especially during heavy rainfall.
Reduced Pump Lifespan
Like any mechanical device, a sump pump has a limited lifespan, which is significantly reduced by constant use. This not only leads to more frequent replacements but also leaves your basement vulnerable during critical times.
Water Damage and Mold
Over time, the inability of a sump pump to manage water properly can result in moisture accumulation in your basement. This environment is ripe for mold growth and water damage, posing health risks and potentially damaging the structure of your home.
Signs Your Sump Pump Is Failing
If your sump pump is always running, then you most likely need to repair or replace it. However, that is not the only sign of a failing sump pump. Some other signs to keep in mind include:
- Unusual noises
- Poor water ejection
- Older age
- Electrical issues
How Long Can a Sump Pump Run Non-Stop?
The length of time a sump pump can run non-stop depends on its quality. High-quality models may operate for extended periods, with some designed to handle several hours of continuous operation (verify with the manufacturer). However, frequent operation accelerates wear and tear, shortening the pump’s lifespan significantly.
Troubleshooting Guide
When faced with a sump pump that won’t turn off, identifying the root cause is the first step toward resolution. Here’s a general guide provided by our basement waterproofing experts at EveryDry Toledo to troubleshooting this issue, followed by some specific tips that homeowners can safely attempt:
General Troubleshooting Guidance
- Inspect the Sump Pit: Begin by checking the sump pit for any visible issues. Ensure there’s no debris obstructing the pump’s intake or the float mechanism. A clear path is crucial for the pump’s operation.
- Evaluate the Float Switch: The float switch is often the culprit in continuous running scenarios. Make sure it’s moving freely and not hindered by any obstructions or tangling.
- Check the Check Valve: Verify that the check valve is installed correctly and functioning. If water is flowing back into the pit, the valve may be faulty or improperly installed.
- Examine the Discharge Line: Ensure the discharge line is clear of any blockages and that water can flow freely away from your home. Clogs can force the pump to work overtime.
Specific Troubleshooting Tips
- Clean the Sump Pit: Remove any debris, stones, or sediment that could interfere with the pump’s operation or float mechanism.
- Adjust or Replace the Float Switch: If the float switch is stuck, try adjusting its position. If problems persist, the switch may need to be replaced.
- Test the Check Valve: Remove the check valve to see if it’s the source of the problem. If water flows back into the pit, it’s likely faulty and needs replacement.
- Flush the Discharge Line: Use a garden hose to flush out the discharge line. If water doesn’t pass through easily, there may be a clog that needs clearing.
When to Call a Professional
If, after these steps, your sump pump continues to constantly run, it may be time to consult a professional. Continuous operation can signal more complex issues that require an expert’s touch.
- If troubleshooting doesn’t resolve the issue
- If the sump pump is old and may require replacement
- When there’s significant or consistent water accumulation that the pump can’t manage
A professional can offer solutions that not only fix the immediate problem but also prevent future occurrences, ensuring your basement remains dry and your sump pump operates efficiently.
Frequently Asked Questions
Learn more about why your sump pump keeps running.
Is It OK for a Sump Pump to Run Constantly?
Some high-quality sump pumps can run consistently for several hours, however, if your sump pump is working more than usual, there may be a problem with your pump or underlying moisture issues that need to be addressed.
Why Does My Sump Pump Run Even When It’s Not Raining?
Some reasons why your sump pump is running even when it is not raining include a clogged discharge line, an improperly sized pump, and underground water leaks. If your sump pump keeps running constantly, it is recommended to inspect it to discover the cause before it fails and stops working.
Is It Normal for a Sump Pump to Run Every 30 Seconds?
While it is normal for sump pumps to run every few minutes after heavy rain, running every 30 seconds indicates that there is probably an issue that needs to be addressed. An example of this could be that a component of the sump pump is not working properly or that your home is right on top of a natural spring or very close to the water table line.
In any case, it is always recommended to inspect your sump pump in order to identify the exact cause and determine a proper solution.
