What is a Sump Pump?

Often unseen but invaluable, a sump pump (also known as a water removal pump) is a device designed to be installed in the lowest part of a basement or crawlspace. What is the purpose of a sump pump? To help keep the area under the building dry and shield it from flooding. Water can encroach on your basement due to excessive rainfall, rapid snow melting, or a high groundwater table. When it does, the sump pump comes to the rescue, springing into action when the water level rises above a certain threshold. The sump pump propels the water away from the home to a predestined area, such as a municipal storm drain or a dry well.


How Does a Sump Pump Work?

Understanding the basic operation of a sump pump is key to comprehending its value in basement maintenance. Below, we delve into the fundamentals of how sump pumps work and the variations available in the market.

The Mechanics of Sump Pumps

The mechanics of sump pumps are straightforward but ingenious. A sump pump resides in a sump pit—a hole constructed in the lowest part of your basement. As water trickles into the pit, the level rises. When the water level reaches a pre-set mark, it triggers a float switch or a pressure sensor within the pump. This activation spurs the pump into action, drawing up the water and directing it through a discharge pipe. This mechanism keeps the water away from your home, ensuring your basement remains dry and your property is unharmed.

Different Types of Sump Pumps

You’ll find two main types of sump pumps in the market—submersible and pedestal pumps.

Submersible sump pumps are designed to work while submerged in water. Their motor, safely nestled in a waterproof casing, allows the pump to be placed directly in the sump pit. Although typically costlier, these pumps are preferred by many homeowners due to their quiet operation and out-of-sight placement.

In contrast, pedestal sump pumps stand tall with their motor hoisted on a pedestal, keeping it clear from water. This design makes them suitable for smaller sump pits, as they don’t need much space for installation. These pumps might produce more noise during operation, but they often come with a smaller price tag and are easier to maintain due to the easily accessible motor.


The Importance of Sump Pumps in Basements

Many people underestimate the role of a sump pump until they face a water problem in their basement. To help emphasize its critical role, let’s discuss how these devices protect our homes and health.

How Sump Pumps for a Basement Prevent Flooding and Water-Related Issues

The principal task of a sump pump is to prevent basement flooding. The pump proves especially vital during periods of heavy rainfall or rapid snow melting, as it efficiently directs water away from the basement. Additionally, sump pumps also help maintain the structural integrity of your home. By reducing the volume of water that collects around the foundation, sump pumps lessen the hydrostatic pressure—the force exerted by water on the basement walls, which can lead to structural damage over time.

Sump pumps also contribute significantly to a healthy living environment. Damp basements are prime grounds for mold and mildew growth, both of which can trigger allergies and respiratory problems. By reducing dampness and controlling humidity levels, a water pump in a basement indirectly aids in maintaining your home’s air quality.


Choosing the Right Sump Pump for Your Basement

Selecting the right sump pump can be a daunting task with multiple options available. Here, we provide guidelines to help you choose the perfect sump pump based on your specific requirements.

Sump Pump Sizing and Capacity Guidelines

When selecting a sump pump, size, and capacity are two critical considerations. The size of the pump should be adequate for your sump pit, and the capacity—measured in gallons per hour (GPH)—should align with the amount of water you expect to handle. An undersized pump may struggle to keep up with heavy water flow, while an oversized pump can lead to unnecessary energy consumption and premature wear and tear.

Submersible Sump Pumps vs. Pedestal Sump Pumps

Submersible sump pumps, though typically pricier, offer a quiet operation and powerful performance, making them ideal for larger basements prone to significant water issues. However, they require more space due to their design and may be more challenging to service because the motor is submerged in water.

On the other hand, pedestal pumps are a cost-effective and dependable choice for smaller basements or homes with less frequent water issues. They are easier to service due to the above-water placement of the motor, but they may produce more noise during operation.


Sump Pump Drainage Options

Understanding where your sump pump’s discharged water goes, and the legal and environmental implications can help ensure responsible and effective operation. Let’s examine these considerations below.

Where Does Sump Pump Water Go?

The water expelled by the sump pump is usually routed away from your home to a prearranged area, such as a municipal storm drain, a dry well, or a nearby pond. However, the discharge location should always comply with local regulations and minimize environmental impact.

Legal Considerations and Environmental Impact

When setting up your sump pump system, it’s important to adhere to local regulations, which may stipulate specific requirements for water discharge to prevent overloading public drain systems or causing water problems for your neighbors. Environmental considerations also play a crucial role in deciding the discharge location. For instance, water discharged onto streets can freeze in winter, creating safety hazards. Meanwhile, water directed to gardens or yards may lead to overwatering and erosion.


Common Issues and Repairs

Now that you know the answer to “How does a sump pump work?” it’s essential to know how to maintain your pump effectively and when it’s time to call in professionals.

Tips for Maintenance and Troubleshooting

Like any mechanical device, a sump pump requires regular maintenance for optimal performance. Basic upkeep involves routine checks for any debris in the sump pit that might impede the pump’s operation, testing the pump by pouring a bucket of water into the pit to ensure it activates and inspecting the discharge line for blockages or frost. Performing these routine checks can significantly enhance the longevity of your sump pump and provide early detection of issues that may require attention.

When to Get Professional Help

While simple maintenance tasks and minor issues with sump pumps can often be addressed by homeowners, some problems warrant professional intervention. For instance, if the pump cycles on and off too frequently or fails to activate during a storm, it’s time to consult a professional. Other issues, such as continuous operation, unusual noises, or visible damage to the motor, also call for expert attention.


Frequently Asked Questions About Sump Pumps

What are the benefits of having a battery back up system for a sump pump?

A battery back up system can provide an additional layer of protection during power outages, which often occur during heavy storms—the very time you need your sump pump for a flooded basement the most. These systems can keep your pump running for several hours even when the power goes out, providing crucial protection against water damage.

Why is my sump pump making loud noises?

Several issues can cause a sump pump to make loud noises. The pump might be sucking in air due to a low water level, the bearings might be worn out, or there might be a problem with the impeller. If you’re not sure about the source of the noise, it’s best to consult with a professional.

How often should I replace my sump pump?

The lifespan of a sump pump varies depending on usage and maintenance, but typically, a sump pump should last between 7 to 10 years. However, if your pump is frequently active or if you’ve noticed a decrease in performance, it might be time for a replacement, even if it has yet to reach the 7-year mark.

What happens if the sump pump fails or overflows?

If the sump pump fails or the basin overflows, water can start to accumulate in your basement, leading to potential water damage, mold growth, and structural issues. It’s important to check your pump regularly to prevent such situations and consider a back up system for added security.

Should I install a sump pump if my basement doesn’t flood?

Even if your basement doesn’t typically flood, a sump pump can still be a valuable investment. Apart from preventing potential flooding, a sump pump can also help control the humidity levels in your basement, discouraging the growth of mold and mildew.

Can I install a sump pump myself?

While some homeowners might feel comfortable installing a sump pump themselves, it’s best to have a professional handle the installation. This is because incorrect installation can lead to numerous issues, from poor water evacuation to complete pump failure.

What should I do if my sump pump keeps running non-stop?

A continuously running sump pump could be due to a stuck switch, a wrongly sized pump, or a faulty check valve. It might also mean that the pump is not powerful enough to handle the amount of water coming in. A professional should evaluate and address Any of these issues.
