Troubleshooting Common Sump Pump Issues: A Guide

October 4, 2023

Sump pumps are essential for homeowners who want to keep their basements and crawl spaces dry. However, like any other appliance, sump pumps can experience problems that need troubleshooting. The most common sump pump issues include switch problems, power issues, and mechanical failures.

Switch problems are among the most common sump pump issues. The switch could be stuck or faulty, preventing the sump pump from turning on. Power issues are also common, and they could result from a tripped circuit breaker, a blown fuse, or a faulty power cord. Mechanical failures, on the other hand, could result from worn-out parts or a damaged impeller. In this article, we will discuss these and other common sump pump issues and provide tips on how to troubleshoot them.

Understanding Sump Pumps

How Sump Pumps Work

A sump pump is a device that is installed in a basement or crawlspace to prevent flooding. It works by collecting water that has accumulated in a sump pit, which is a hole in the ground that is dug out to collect water. The pump then pumps the water out of the pit and away from the home, preventing flooding and water damage.

Sump pumps are typically powered by electricity and have a float switch that turns the pump on and off depending on the water level in the pit. When the water level rises, the float switch activates the pump, which then pumps the water out of the pit. Once the water level has been lowered, the float switch turns the pump off.

Types of Sump Pumps

There are two main types of sump pumps: pedestal and submersible.

Pedestal sump pumps have the motor mounted on a pedestal above the sump pit, with a hose or pipe running down into the pit to pump the water out. These pumps are less expensive and easier to maintain, but they are also louder and less powerful than submersible pumps.

Submersible sump pumps, on the other hand, are installed inside the sump pit and are completely submerged in water. They are more expensive and harder to maintain, but they are also quieter and more powerful than pedestal pumps.

It's important to choose the right type of sump pump for your needs based on factors like the size of your basement or crawlspace, the amount of water that typically accumulates, and your budget.

Common Sump Pump Issues

Sump pumps are an essential tool for keeping basements and crawl spaces dry. However, like any mechanical device, they can experience problems that require troubleshooting. Here are some common sump pump issues and how to fix them:

Continuous Running

If your sump pump runs continuously, it can be a sign of several issues. One possible cause is a stuck float switch. Check if the switch is stuck in the "on" position and try to free it. Another possible cause is a high water table, which can cause the pump to run continuously. In this case, you may need to install a larger pump or a second pump.

Loud Noises

If your sump pump is making loud noises, it could be due to several reasons. One common cause is a clogged impeller, which can cause the pump to strain and make noise. To fix this issue, turn off the power and remove the pump to clean the impeller. Another possible cause is a loose or damaged discharge pipe. Check the pipe for any damage or loose connections and tighten them if necessary.

Frequent Cycling

If your sump pump cycles on and off frequently, it could be due to a few reasons. One possible cause is a switch problem. Check if the switch is stuck or damaged and replace it if necessary. Another possible cause is a pump that is too small for the job. In this case, you may need to install a larger pump.

Water Not Pumping

If your sump pump is not pumping water, it could be due to several reasons. One possible cause is a clogged intake screen. Check the screen for any debris and clean it if necessary. Another possible cause is a damaged impeller. Check the impeller for any damage and replace it if necessary. Finally, a faulty check valve can prevent water from pumping. Check the valve for any damage and replace it if necessary.

In summary, sump pump issues can be a hassle, but they can be fixed with proper troubleshooting. By following the steps outlined above, homeowners can ensure that their sump pumps are functioning correctly and keeping their basements and crawl spaces dry.

Troubleshooting Sump Pumps

When a sump pump fails, it can lead to costly water damage in your basement. Troubleshooting the issue can help you identify the problem and fix it before it becomes a major issue. Here are some common steps to take when troubleshooting your sump pump.

Checking for Power Issues

The first step in troubleshooting a sump pump is to make sure it's receiving power. Check the circuit breaker to ensure it hasn't tripped. If the breaker is on, check the power cord to ensure it's plugged in and the outlet is functioning properly. If the power cord is damaged, it may need to be replaced.

Inspecting the Float Switch

The float switch is responsible for turning the sump pump on and off as the water level in the sump pit rises and falls. If the switch is stuck or damaged, the pump may not turn on. Check the switch to ensure it's not stuck or obstructed. If it's damaged, it may need to be replaced.

Assessing the Check Valve

The check valve is responsible for preventing water from flowing back into the sump pit once it's been pumped out. If the valve is stuck or damaged, it can prevent the pump from working properly. Check the valve to ensure it's not stuck or obstructed. If it's damaged, it may need to be replaced.

Examining the Discharge Line

The discharge line is responsible for carrying water away from the sump pump and out of your basement. If the line is clogged or damaged, it can prevent the pump from working properly. Check the line to ensure it's not clogged or obstructed. If it's damaged, it may need to be repaired or replaced.

By following these steps, you can troubleshoot common sump pump issues and keep your basement dry and free of water damage.

Preventive Measures

To avoid sump pump problems, it is important to take preventive measures. These measures include routine maintenance and professional inspection.

Routine Maintenance

Performing routine maintenance on your sump pump can prevent common problems and extend its lifespan. Here are some maintenance tasks to consider:

  • Clean the sump pump pit: Debris and sediment can accumulate in the pit, obstructing the pump and reducing its efficiency. Regularly clean the pit to prevent this.
  • Check the float switch: The float switch is responsible for turning the pump on and off. Ensure that it is not obstructed or damaged and moves freely.
  • Test the pump: Test the pump regularly to ensure it is functioning properly. Pour water into the pit to activate the pump and ensure it is discharging water correctly.
  • Check the discharge line: Ensure that the discharge line is not blocked or frozen. Blocked or frozen lines can cause the pump to overwork and eventually fail.

Professional Inspection

In addition to routine maintenance, it is important to have a professional inspect your sump pump periodically. A professional inspection can identify potential issues and prevent costly repairs. Here are some reasons to consider a professional inspection:

  • Experience: Professionals have experience working with sump pumps and can identify potential issues that may be missed by a homeowner.
  • Testing: Professionals can test the pump and discharge line to ensure they are functioning properly and identify potential issues.
  • Repairs: If an issue is identified, professionals can make necessary repairs to prevent further damage to the pump or property.

By performing routine maintenance and having a professional inspection, homeowners can prevent common sump pump problems and ensure their sump pump is functioning properly.

Conclusion

In conclusion, sump pumps are an essential tool for preventing basement flooding and water damage. However, like any mechanical device, they can experience problems and malfunctions. By understanding the common issues that can arise with sump pumps and how to troubleshoot them, homeowners can ensure their sump pump is functioning properly and protect their home from water damage.
