If you’ve ever experienced a flooded basement or the aftermath of water damage, you know how important a sump pump can be. This device is designed to keep your basement dry by collecting excess water and pumping it outside your home. However, like any mechanical device, sump pumps can sometimes fail to function properly, leaving you vulnerable to potential water damage.
There can be numerous reasons why your sump pump is not working, and it’s crucial to identify the problem and address it promptly. One common issue is a power outage or a tripped circuit breaker, which can cause the pump to stop working. Checking the power source and ensuring it’s functioning correctly is the first step in troubleshooting the problem.
Another possible cause of sump pump failure is a stuck or jammed float switch. The float switch is responsible for activating the pump when the water level rises above a certain point. If the float switch gets stuck in the “off” position or becomes obstructed by debris, the pump won’t turn on, and water will continue to accumulate. Regular maintenance and cleaning of the float switch are essential to prevent this issue.
Additionally, a clogged or frozen discharge pipe can also hinder the operation of your sump pump. Over time, debris such as dirt, leaves, or small rocks can accumulate in the discharge pipe, impeding the flow of water. In colder climates, the pipe can freeze during winter, preventing the water from being expelled outside. Inspecting and clearing the discharge pipe regularly can help prevent this problem from occurring.
To ensure the effectiveness of your sump pump and protect your basement from potential water damage, it’s crucial to address any issues promptly. Identifying the cause of the problem, whether it’s a power issue, a malfunctioning float switch, or a clogged discharge pipe, is the first step in troubleshooting your sump pump.

Pump Overload
If your sump pump is not working, it might be due to pump overload. This can happen when there is too much water entering the sump pump pit at once, causing the pump to work harder than it is designed to. As a result, the pump may overheat and shut down.
One way to prevent pump overload is to install a larger capacity sump pump that can handle a higher volume of water. Additionally, you can consider installing a backup sump pump system to help distribute the workload and ensure that your basement stays dry even during heavy rainfall.
It is also important to regularly maintain your sump pump by cleaning the intake screen and checking the float switch for proper operation. These simple steps can help prevent pump overload and extend the lifespan of your sump pump.
If you are experiencing pump overload despite taking these precautions, it may be a sign of a more serious issue with your drainage system. In this case, it is recommended to contact a professional plumber who can assess the problem and provide the necessary repairs or upgrades.
Malfunctioning Check Valve
A sump pump relies on a check valve to prevent the water it pumps out from flowing back into the sump pit. This check valve is designed to allow water to flow in only one direction, away from the sump pump and towards the discharge pipe that leads outside.
If your sump pump is not working properly, a malfunctioning check valve could be the culprit. Here are some signs that your check valve may be malfunctioning:
- Noisy Operation: If you hear strange noises coming from your sump pump when it kicks on, it could be a sign that the check valve is not closing properly. This can cause water to flow back into the sump pit, leading to repeated cycling of the pump.
- Reduced Pumping Capacity: A malfunctioning check valve can also reduce the pumping capacity of your sump pump. This means that it may not be able to remove water effectively from the sump pit, leading to water accumulation and potential flooding.
- Continuous Running: If your sump pump seems to be running continuously without shutting off, it could be due to a malfunctioning check valve. When the check valve fails to close properly, water can flow back into the sump pit, causing the pump to run more frequently.
To troubleshoot a malfunctioning check valve, you can try the following steps:
- Inspect the check valve for any visible signs of damage or clogs. Obstructions or debris can prevent the valve from closing properly.
- If there are no visible issues, remove the check valve and clean it thoroughly. Use a pipe brush or similar tool to remove any buildup or sediment that may be affecting its operation.
- If cleaning the check valve does not resolve the issue, it may need to be replaced. Consult the manufacturer’s instructions or contact a professional plumber for assistance.
Regular maintenance and inspection of your sump pump and check valve can help prevent malfunctions and ensure proper functioning. Consider scheduling an annual check-up with a qualified professional to keep your sump pump system in good working order.
