How to Fix a Sump Pump That Has Stopped Working

how to fix a sump pump

A sump pump plays a crucial role in keeping your basement dry and preventing water damage to your home. It is designed to remove water that accumulates in a sump basin, typically found in the basement of homes. By pumping out excess water, it helps to protect your property from flooding, mold growth, and structural damage. Understanding the importance of a sump pump is the first step in appreciating the need for regular maintenance and timely repairs.

Identifying Common Sump Pump Problems

Before you can fix a sump pump that has stopped working, it is essential to identify the common problems that can affect its performance. Some of the most frequent issues include:

  • Power failure or electrical issues
  • Clogged or frozen discharge pipes
  • Faulty float switch
  • Damaged impeller
  • Check valve malfunction
  • Debris buildup in the sump basin

By recognizing these common problems, you can better diagnose the issue and take appropriate steps to resolve it.

Initial Checks Before Troubleshooting

Before diving into more detailed troubleshooting, it is important to perform some initial checks to rule out simple issues. Ensure that the sump pump is plugged in properly and that the circuit breaker has not tripped. Additionally, check for any obvious signs of damage or wear and tear. These preliminary checks can help you quickly identify and resolve minor problems without the need for extensive repairs.

Inspecting the Power Source

A common reason for a sump pump to stop working is a power failure or electrical issue. Start by inspecting the power source to ensure that the pump is receiving electricity. Check the power cord for any signs of damage, such as fraying or exposed wires. If the power cord appears to be in good condition, test the outlet by plugging in another device to see if it works. If the outlet is not providing power, you may need to reset the circuit breaker or replace a blown fuse.

Examining the Float Switch

The float switch is a critical component of the sump pump that activates the pump when the water level rises. If the float switch is not functioning properly, the pump may not turn on. To examine the float switch, remove the sump pump from the basin and inspect the switch for any visible damage or obstructions. Ensure that the float moves freely and is not stuck. If the float switch is damaged, it may need to be replaced to restore proper operation.

Clearing Obstructions in the Discharge Pipe

Clogged or frozen discharge pipes can prevent the sump pump from effectively removing water from the basin. To clear obstructions in the discharge pipe, start by disconnecting the pipe from the pump. Use a plumber’s snake or a power washer to remove any blockages. If the discharge pipe is frozen, thaw it using a heat gun or warm water. Once the pipe is clear, reconnect it to the pump and test the system to ensure proper water flow.

Checking the Impeller for Damage

The impeller is a rotating component that helps to move water through the sump pump. If the impeller is damaged or clogged with debris, the pump may not function correctly. To check the impeller, remove the pump from the basin and disassemble the housing to access the impeller. Inspect the impeller for any signs of damage, such as cracks or broken blades. Clean any debris from the impeller and housing, and replace the impeller if necessary.

Testing the Check Valve

The check valve is designed to prevent water from flowing back into the sump basin after it has been pumped out. A malfunctioning check valve can cause the pump to work harder and reduce its efficiency. To test the check valve, remove it from the discharge pipe and inspect it for any signs of wear or damage. Ensure that the valve opens and closes properly. If the check valve is faulty, replace it with a new one to maintain optimal pump performance.

Maintaining Your Sump Pump

Regular maintenance is key to ensuring the longevity and reliability of your sump pump. Some essential maintenance tasks include:

  • Inspecting and cleaning the pump and its components
  • Testing the pump periodically to ensure it is functioning correctly
  • Checking the discharge pipe for clogs or damage
  • Replacing worn or damaged parts as needed

By performing these maintenance tasks, you can prevent many common issues and keep your sump pump in good working condition.

When to Call a Professional

While many sump pump issues can be resolved with DIY troubleshooting and repairs, there are times when it is best to call a plumber. If you are unable to identify the problem, or if the repairs are beyond your skill level, a professional plumber can provide expert assistance. Additionally, if your sump pump is old or has experienced significant damage, it may be more cost-effective to replace the sump pump rather than attempting extensive repairs. A plumber can help you determine the best course of action and ensure that your sump pump is operating efficiently.

Preventing Sump Pump Malfunctions: A Guide for Homeowners

a sump pump is a great form of a residential flood control system.

Sump pump malfunctions rank among the top ten causes of the worst flooding in homes. Any flooding in your home will cause severe emotional pain and financial loss. But the pain is worse when that flooding is from a sump pump failure. That is because the entire purpose of having a sump pump in your home is to prevent flooding.

Sump pumps are designed to keep protecting your home after other flood defenses have failed. Most of a home’s flood defenses are located outside; to keep water from entering the house. But the sump pump is located inside the building. If floodwaters elude the other flood defenses and enter the home, the sump pump removes the water.

But sometimes, this does not happen because the sump pump fails. Real Property Group Company says most sump pump failures will go undetected by the homeowner. Homeowners only become aware of the issues with the sump pump after their home has been flooded. What is the point of installing a sump pump in your home if you cannot sleep knowing that your home is protected from floods?

The good news is there are ways to prevent sump pump failure. You can prevent basement flood damage by early detection of problems in your sump pump. This post explains the simple steps to ensure your sump pump is always functional. These suggestions work best if you have a schedule for doing all the checks at predetermined times during the year.

Common sump pump problems and how to solve them

Power failure

Electrical problems cause more sump pump failures than mechanical issues. These electrical problems can be due to power outages during stormy weather. They can also be due to negligence, such as when someone unplugs the sump pump or accidentally shuts off the circuit breaker. Problems in a home’s electrical wiring may also cause sump pump failure. Routine checks to ensure the sump pump is plugged in and getting power will help you avoid this problem.

Float switch problems

A malfunctioning float switch is the second most common cause of sump pump failure. Float switch problems happen because the pump has shifted inside the pit, the float is stuck, or debris is interfering with it. To test the float switch, fill the pit with water and watch to see if the float switch will trigger the pump and switch it off at the right time. To avoid float issues, ensure the pit is clean and the pump is positioned properly.

Clogged or frozen discharge lines

If the discharge line is frozen or clogged, water will not flow to the designated discharge point. Instead, it will flow backwards, down the line and into the basement. That will make the sump pump overwork, which can burn the motor. Installing a grated covering on the end of the discharge line will keep debris out. To prevent freezing, use sturdy PVC pipes, make sure the discharge line has a good slope and install a pop-up drain in your yard.

Check valve failure

The check valve is a one-way valve that prevents discharged water from back-flowing into the sump pump. It is often located in the vertical portion of the discharge line, close to where it connects to the sump pump. A damaged check valve will keep your sump pump cycling on and off continuously. The check valve will make a noise or vibrate if it is broken. A damaged check valve should be replaced.

Undersized sump pit or sump pump

Your home will be vulnerable to flooding if the sump pit is inadequate for the amount of water that enters the basement or if the sump pump is too small. Make sure your sump pit and sump pump match the requirements of your home. If the sump pump is too small for your home, it will overwork. That will lead to your sump pump motor burning out. It will also make it prone to a lot of other issues.

Redundant sump pump

A redundant sump system uses two sump pumps in the same sump pit. If one of the sump pumps fails, you can rely on the other one to keep your home safe.

Battery-powered sump pump

A battery-powered sump pump will work even when there is a power outage. Since power outages typically coincide with heavy rainfall, a battery backup installation of your sump pump is highly recommended.

To conclude, one of the best ways to ensure that your sump pump performs as expected is to have an expert install the system. The risk of sump pump failure can be halved by proper installation. It is also a good practice to have a plumber do a thorough inspection of your sump pump system periodically.
