A sump pump is an essential tool for preventing mold growth in basements and crawl spaces. This device is designed to help remove excess water that accumulates in these areas, especially during heavy rainstorms or flooding. Like any other mechanical system, sump pumps can fail and cause significant damage if you don’t act fast.
Here are the common reasons for sump pump failure and how that failure might lead to mold growth. We will also provide tips on how to prevent your sump pump from failing and steps to take if it does stop working properly.
What is Sump Pump Failure?
Sump pump failure occurs when the pump is unable to effectively remove excess water from your basement or crawlspace. This can happen due to power outages, mechanical malfunctions, clogged discharge pipes, or inadequate maintenance.
When a sump pump fails, the water that should be pumped out of your basement or crawlspace will continue to accumulate, creating the perfect environment for mold growth. Mold thrives in damp and dark conditions, and a flooded basement or crawlspace provides just that.
The longer the water sits in these areas, the more damage it can cause to your property’s structure and belongings. You have to deal with sump pump failure quickly to prevent mold growth and mitigate any potential damage.
Common Causes of Sump Pump Failure
There are various reasons why a sump pump may fail, including:
Power Outages
One of the most common causes of sump pump failure is power outages. During heavy rainstorms or flooding, power outages are not uncommon, and they can leave your sump pump without electricity to function.
Without a backup power source, such as a generator or battery backup system, your sump pump will be unable to remove excess water from your basement or crawlspace, leading to potential flooding and mold growth.
To prevent sump pump failure during power outages, it is crucial to have a backup power source in place. This will ensure that your sump pump can continue working even when the electricity goes out.
Mechanical Malfunctions
Mechanical malfunctions, such as a malfunctioning float switch or motor, can also lead to sump pump failure. These components are essential for the proper functioning of a sump pump, and if they malfunction, the pump will be unable to remove water effectively.
Regular maintenance and inspections can help identify any potential mechanical issues and prevent them from causing sump pump failure. It is recommended to have your sump pump inspected at least once a year by a professional.

Clogged Discharge Pipes
Another common cause of sump pump failure is clogged discharge pipes. Over time, debris and sediment can build up in the pipes, restricting water flow and causing the pump to work harder. This can result in mechanical failures and ultimately lead to sump pump failure.
Regularly clean and maintain your discharge pipes to prevent this from happening, especially after heavy rainstorms or flooding.
Improper Installation
Improper installation of a sump pump can also cause it to fail. If the pump is not installed correctly, it may not be able to effectively remove water from your basement or crawlspace, leading to potential flooding and mold growth.
Have a professional, like Patriot Property Restoration, install your sump pump to ensure it is installed correctly and in the best location for maximum effectiveness.
Lack of regular maintenance
If a sump pump is not maintained properly it will be more likely to fail. They require routine maintenance, just like your car or your hvac system. Without it, components can wear out or malfunction, leading to potential failure when you need the pump most.
To prevent this, it is crucial to schedule regular maintenance for your sump pump and address any potential issues promptly.
What is the most common reason for sump pump failure?
The most common reason for sump pump failure is power outages. During heavy rainstorms or flooding, power outages are not uncommon, and they can leave your sump pump without electricity to function.
Without a backup power source, such as a generator or battery backup system, your sump pump will be unable to remove excess water from your basement or crawlspace, leading to potential flooding and mold growth. Plus, power outages can occur at any time, making it difficult to predict and prepare for.
To prevent sump pump failure due to power outages, it is crucial to have a backup power source in place. This could be a generator or battery backup system that will kick in automatically when the electricity goes out.
Additionally, be sure to regularly maintain your backup power source and ensure it is in good working condition. This will ensure that it is ready to provide electricity when needed and prevent any potential failures. Having a battery backup system can also be beneficial as it can continue to power your sump pump even if the power outage lasts for an extended period.
Future Tips for Preventing Sump Pump Failure
To prevent sump pump failure and potential mold growth, here are a few tips to keep in mind:
- Schedule regular maintenance: As mentioned earlier, regular maintenance for your sump pump is crucial to its proper functioning. Schedule annual inspections and address any potential issues promptly.
- Invest in a backup power source: Having a backup power source, such as a generator or battery backup system, can prevent sump pump failure during power outages.
- Clean and maintain discharge pipes: Regularly clean and maintain your discharge pipes to prevent clogs that can lead to sump pump failure.
- Monitor weather and water levels: Keep an eye on the weather forecast and check water levels in your basement or crawlspace regularly, especially during heavy rainstorms. This will allow you to address any potential issues before they become a problem.
- Consider upgrading your sump pump: If your sump pump is older or has a history of failure, it may be time to consider upgrading to a newer and more reliable model.
By following these tips, you can help prevent sump pump failure and ensure that your home remains protected from potential water damage and mold growth. Remember, addressing any issues promptly is key to preventing costly repairs and ensuring the longevity of your sump pump.
Why is my sump pump not kicking in?
If your sump pump is not kicking in, there could be several reasons for this. The most common reason is a power outage or electrical malfunction. If the pump is not receiving electricity, it will not be able to turn on and remove water from your basement or crawlspace.
In this case, having a backup power source can prevent sump pump failure during power outages.
Another reason for a sump pump not kicking in could be a malfunctioning float switch. The float switch is responsible for turning the pump on and off as the water levels rise and fall. If it is not functioning correctly, the pump may not turn on, even when needed.
It could also be due to mechanical malfunctions, such as a faulty motor, impeller, or valve. Regular maintenance and inspections can help identify these issues before they lead to sump pump failure.
In some cases, the discharge pipe may also be clogged, preventing water from flowing out of the pump and causing it not to kick in. It is essential to clean and maintain your discharge pipes regularly.
If you are unsure why your sump pump is not kicking in, it is best to call a professional for an inspection. They can identify the root cause and make any necessary repairs to ensure your sump pump is functioning correctly.
Can sump pumps grow mold?
Yes, sump pumps can grow mold if not properly maintained or if they fail to remove excess water from your basement or crawlspace. Mold thrives in damp and dark environments, making a sump pump’s pit an ideal breeding ground.
When a sump pump fails to remove water from the pit, it can accumulate and create stagnant water, providing a perfect environment for mold to grow. Additionally, if the sump pump is not maintained regularly, it can become clogged with debris and organic materials that also contribute to mold growth.
Mold growth in sump pumps can lead to potential health hazards as mold spores can spread through the air and cause respiratory issues. It can also damage the structural integrity of your home and cause unpleasant odors.
To prevent mold growth in your sump pump, it is crucial to schedule regular maintenance and address any potential issues promptly. This includes cleaning and maintaining the pump, discharge pipes, and backup power source.
If you suspect that your sump pump has already grown mold, it is best to call a professional for proper mold remediation. They can safely remove the mold and address any underlying issues to prevent future growth. Remember, prevention is key when it comes to mold growth in sump pumps.
Mistakes to Avoid with Sump Pump Maintenance
To ensure that your sump pump is functioning correctly and prevent potential failures, here are some common mistakes to avoid with sump pump maintenance:
- Ignoring regular maintenance: Regular maintenance is required for the proper functioning of your sump pump. Ignoring it can lead to clogs, malfunctions, and potential mold growth.
- Not testing the backup power source: It is important to test your backup power source, whether it’s a generator or battery backup system, regularly. This will ensure that it is ready to kick in during a power outage.
- Skipping inspections and repairs: If you notice any issues with your sump pump, such as strange noises or prolonged running times, do not ignore them. Call a professional for an inspection and address any necessary repairs promptly.
By avoiding these common mistakes, you can ensure that your sump pump remains in good working condition and protect your home from potential water damage. Remember, regular maintenance and prompt repairs are key to a functioning sump pump.
What is the life expectancy of a sump pump?
The average life expectancy of a sump pump is around 10 years. However, this can vary depending on the type and quality of the pump, as well as how well it is maintained.
Submersible sump pumps typically have a longer lifespan compared to pedestal pumps, which are more susceptible to damage and wear due to their exposed motor.
Factors that can affect the lifespan of a sump pump include:
- Frequency of use: A sump pump that runs more often may have a shorter lifespan due to wear and tear on its components.
- Quality of installation: If a sump pump is not installed correctly or in a suitable location, it may experience more strain and have a shorter lifespan.
- Quality of maintenance: Regular maintenance can extend the lifespan of a sump pump by identifying and addressing any issues before they become more severe.
- Power outages: Frequent power outages can cause a sump pump to work overtime, leading to premature failure.
- Type of water being pumped: If the water being pumped contains debris or is highly corrosive, it can cause damage to the pump’s components and reduce its lifespan.
To ensure that your sump pump lasts as long as possible, it is essential to invest in a high-quality pump, have Patriot come in and provide a professional sump pump installation, and schedule regular maintenance. This will extend its lifespan and ensure that it functions properly when needed to protect your home from water damage.
