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. Learning how to fix a sump pump yourself can save you money from a premature sump pump replacement.

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.

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

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:

Cleaning the sump basin and removing debris

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.

A basement sump pump is one of those equipment’s you don’t get to use often. For most of the year, you may have no reason to think about the sump pump. But when the occasion arises for its use, you want your sump pump to be up to anything nature throws at it. One of the worst home emergencies to have is a sump pump failure.

Sump pumps protect your home from water intrusion but as Alliance Property Management team explains, since they are out of sight in the basement, it is easy to neglect this essential equipment. The wake-up is usually when you go down to the basement and accidentally step into ankle-deep ice-cold water. But you’re lucky if this is all that happens; you could make the discovery in worse circumstances.

Like any other component of your home, the sump pump needs maintenance. Sump pumps are hardy pieces of equipment but even the hardiest device can break down unexpectedly, especially if it is not getting the required care. There are several things that can cause your sump pump to fail but most of them can be prevented with timely maintenance of the equipment.

Common causes of sump pump failure

The most frequent issues you will have with a sump pump are:

Mechanical problems: Issues with the pressure sensor or float activator arm. The float arm is the on/off switch for the pump. If it is out of order, the pump will not kick in when there is water in the sump pit.
Electrical problems: Power outages during a severe storm will cut off the power supply to the equipment. Power surges could also damage its electrical components.
Blocked/frozen discharge lines: If debris or small animals gets into the pipe, it could get blocked. Pipes may also be blocked by ice or snow.

Sump pump maintenance routine

To keep the sump pump from getting problems, you should run the equipment periodically and also check the function of its various components. Looking after your basement sump pump is not difficult. You just need to create a schedule for sump pump maintenance. You should also know the important tasks to do during maintenance.

Test the float

The float is the part of the sump pump most likely to suffer damage. The pump will not work if the float is damaged because the float triggers the pump. To check if the float is working, slowly pour water into the sump pit until the float rises and the pump activates. If the pump activates, it should also shut off after the water is removed. If this happens, the float is fine.

Clean the sump pit

Debris – mostly soil materials – will usually find its way into the pit along with water. Debris inside the sump pit can give you a lot of problems. Solid materials in the pit can interfere with the function of the float. Sometimes when you think you have a float issue, it could actually be the debris in the pit that is the real problem. Before attempting to deal with float issues, first clean out the debris and do it regularly.

Test the check valve

If, when you pour water into the pit to check the float, the pump is triggered but the water, instead of being removed returns to the pit, you have a problem with the check valve. Another sign that the check valve may be damaged is when water stays longer in the pit than it should. Diagnosing check valve issues is a bit complex; it is best to have an expert look at the sump pump.

Clean the impeller

This is another problem that could be caused by debris. Normally, any debris that enters the sump pump should be captured by the screen. However, if this does not happen, dirt can accumulate on the impeller and jam it. This is a common cause of sump pump damage, but it is easily solved.

Simply unplug the pump, disconnect its piping to remove it from the pit, and then disassemble it to remove the screen and impeller. Clean the impeller and return it to its place inside the pump.

Check the power supply

Faulty electrical connections can damage the sump pump or cut-off electricity supply to the equipment. When you test the pump as described in the section on checking the float, if the sump pump does not trigger, check the electricity supply before trying anything else. The pump may not be properly plugged in or there could be a problem with the circuit breaker.

Install an alarm

This step is more of a precautionary measure; it does not deal directly with maintaining the sump pump. A sump pump alarm will alert you when your sump pump has stopped working. Some alarms can be configured to send an SMS or email when there is a problem. Installing an alarm will eliminate any chances that you will be caught off-guard by a sump pump failure that requires repair.
