Do I need a sump pump?

If your home has a basement, then yes, because it’s almost a guarantee that every basement will flood at least once. And the likelihood of a flood occurring greatly increases if you live in an area that has a high water table, or receives a lot of rain/snow. Also, sump pumps are just as useful in high moisture areas, i.e., basements.




What are the benefits of having a sump pump?

Using a sump pump in your home offers several benefits, especially if you live in an area prone to heavy rainfall, flooding, or high water table levels. Here are some of the key advantages of installing a sump pump:

Basement and Crawl Space Protection:
One of the primary benefits of a sump pump is the protection it provides to your basement or crawl space. These areas are vulnerable to water damage, especially during heavy rainstorms or when groundwater levels rise. A sump pump helps prevent water from seeping into these spaces, reducing the risk of structural damage, mold growth, and the loss of valuable belongings.

Flooding Prevention:
By effectively removing water from your sump pit, a sump pump helps prevent basement flooding. It serves as a proactive measure against water accumulation, ensuring that excess water is promptly and efficiently pumped away from your home’s foundation. This can save you from the costly and time-consuming process of dealing with water damage restoration.

Mold and Mildew Prevention:
Excessive moisture in your basement or crawl space can lead to mold and mildew growth. These fungi thrive in damp environments and can pose health risks to you and your family. By keeping these areas dry and free from excess moisture, a sump pump helps prevent the growth of mold, protecting your indoor air quality and reducing the risk of respiratory issues.

Protects Foundation and Structural Integrity:
When water accumulates around your home’s foundation, it can cause soil erosion, foundation cracks, and structural damage over time. A sump pump mitigates this risk by actively removing water and maintaining a dry foundation. By preserving the integrity of your foundation, you can avoid costly repairs and maintain the value of your home.

Peace of Mind:
Installing a sump pump provides peace of mind, especially during heavy rainstorms or when you’re away from home. You can rest assured that the pump is continuously monitoring and removing water from your sump pit, reducing the risk of unexpected flooding or water damage. This added protection allows you to focus on other aspects of your life without worrying about potential water-related issues.

Increased Home Value:
A properly installed and functioning sump pump can enhance the value of your home. Potential buyers view a sump pump as an important feature that offers protection against water damage and flooding. It can give them confidence in the home’s structural integrity and provide peace of mind knowing that the property is equipped to handle potential water-related challenges.


Things to look for when choosing a sump pump

There are several factors to consider when it comes to selecting the best sump pump for your needs. Each home and situation is unique, so it’s important to assess these factors before making a decision. In this section, we will discuss the key considerations to keep in mind when choosing a sump pump.

Pump type

There are two main types of sump pumps: submersible and pedestal. Submersible pumps are installed inside the sump pit, and is submerged in water. They are typically more expensive but offer quieter operation and are less prone to clogging. Pedestal pumps, on the other hand, have a motor mounted above the sump pit. They are more affordable and easier to maintain but tend to be louder and more visible.

Pump power

The power of a sump pump is measured in horsepower (HP). The appropriate HP rating for your sump pump will depend on the size of your basement or crawl space, the depth of the pit, and the amount of water you expect to handle. It’s important to choose a pump with sufficient power to effectively remove water from the pit and handle potential heavy rainfalls or flooding.

Pump capacity

Sump pump capacity is measured in gallons per minute (GPM) or gallons per hour (GPH). This indicates how much water the pump can move within a specific time frame. Consider the drainage requirements of your space and choose a pump with a capacity that can handle the expected water volume. It’s better to choose a slightly higher capacity than you think you’ll need to ensure adequate water removal.

Switch type

The switch is a critical component of the sump pump as it controls when the pump activates and deactivates. The two main types of switches are float switches and pressure switches. Float switches operate by rising with the water level and triggering the pump when it reaches a certain point. Pressure switches, on the other hand, sense water pressure and activate the pump accordingly. Choose a switch type that suits your preferences and offers reliable and consistent performance.

Backup system

Consider investing in a sump pump with a backup system to ensure uninterrupted operation, even during power outages. Backup systems can include battery-powered pumps, water-powered pumps, or generator backup. These systems provide added peace of mind and protect your home during emergencies when power supply is disrupted.

Durability and build quality

Look for a sump pump that is constructed with durable materials and is built to withstand prolonged use. Stainless steel or cast iron pumps are typically more durable and resistant to corrosion, ensuring a longer lifespan. Pay attention to the build quality, seals, and overall construction of the pump to ensure it can handle the demands of continuous operation.

Warranty and customer support

Check the warranty offered by the manufacturer and the availability of customer support. A reliable warranty provides assurance and indicates the manufacturer’s confidence in their product. Additionally, accessible customer support can be invaluable if you encounter any issues or have questions about the installation or maintenance of your sump pump.

How long does a sump pump last?

A sump pump can last for up to 10 to 12 years – as long as you invest in a quality system that you clean and have maintenance done regularly. Cheap, or even neglected quality pumps, likewise, are likely to fail long before their due date.

Regardless, you can expect to change components like float switches multiple times throughout the life of a sump pump.


How often should a sump pump run?

They run automatically when needed. A submersible sump pump, for example, sits in a pit, because the water in the ground underneath the basement will naturally be drawn to it.

As soon as the water level in this pit reaches a certain level, it triggers the float switch, which activates the sump pump. So, in other words, it only runs when the water in the pit reaches a certain level.


How powerful should my sump pump be?

The power or capacity of a sump pump is an important consideration to ensure its effectiveness in removing water from your sump pit. Required power of a sump pump is typically determined by factors such as the size of your basement or crawl space, the water table level in your area, and the amount of rainfall or water accumulation you anticipate.

The power of a sump pump is commonly measured in horsepower (HP) and refers to the motor’s ability to pump water. Sump pumps typically range in power from 1/4 HP to 1 HP, with higher HP indicating a more powerful pump. Here are some general guidelines to help you determine the appropriate power for your sump pump:

Residential Use: For most residential applications, a sump pump with 1/3 HP to 1/2 HP is usually sufficient. These pumps can effectively handle moderate water accumulation and provide reliable performance for typical basement or crawl space sizes.

High Water Table or Heavy Rainfall: If you live in an area with a high water table, frequent heavy rainfall, or have a larger basement/crawl space, you may need a more powerful sump pump. Consider a pump with 3/4 HP to 1 HP to handle larger volumes of water and ensure effective water removal.


Where should a sump pump drain to?

A sump pump should drain water to a location that is safe and appropriate for effective water disposal. The ideal drainage location may vary depending on local regulations, property layout, and environmental considerations. Here are some common options for sump pump discharge:

Storm Drain or Municipal Sewer:
Check local building codes and regulations to determine if it is permissible to discharge the sump pump water directly into a storm drain or the municipal sewer system. Some areas allow this method, but others may have restrictions or require permits.

Exterior Drainage:
The sump pump can be designed to discharge water to a designated area on your property, away from the foundation. This can be achieved by installing a pipe or hose that directs the water to a suitable location such as a drainage ditch, a dry well, a vegetated area, or an area with proper grading that allows for water absorption.

French Drain System:
A French drain is a drainage system designed to collect and redirect water away from an area. It consists of a trench filled with gravel or perforated pipe surrounded by gravel. The sump pump can discharge water into the French drain system, which will then carry the water away from the foundation.

Rain Barrel or Collection System:
In some cases, you may want to reuse the sump pump water for other purposes such as watering plants or gardens. You can connect the sump pump to a rain barrel or collection system, which allows you to capture and store the water for later use.


Why is there a bad odor coming from my sump pump?

If your sump pump is emitting an unpleasant odor, it could be a sign of underlying issues that need to be addressed. Here are some possible reasons why your sump pump may stink:

Clogged or Dirty Sump Pit:
If the sump pit becomes clogged with debris, dirt, or sediment, it can create an environment conducive to bacterial growth and odor. Regular maintenance, including cleaning the sump pit, can help prevent this issue.

Lack of Ventilation:
Inadequate air circulation around the sump pump can contribute to a musty or foul smell. Without proper ventilation, the moisture in the sump pit can become trapped and give rise to unpleasant odors. Ensure there is proper airflow in the area by providing ventilation or using a fan.

Sewage Backup:
If your sump pump is connected to a sewage ejector system or if there is a sewage line nearby, a sewage backup can cause a strong, sewage-like odor in the sump pump. This typically occurs when there is a blockage or malfunction in the sewage system. In such cases, it is important to address the issue promptly and consult a professional plumber.

Improper Discharge:
If the sump pump is discharging water too close to the foundation or into an area with poor drainage, the water may seep back into the sump pit, causing stagnant water and odor issues. Ensure that the discharge pipe is properly installed and directed away from the foundation and that the water is being effectively drained.

To address the smell coming from your sump pump, consider the following steps:

Clean the Sump Pit:
Regularly clean the sump pit to remove debris, sediment, and stagnant water. Use a pump or a wet/dry vacuum to drain the water and clean the pit thoroughly.

Disinfect and Deodorize:
After cleaning the sump pit, disinfect it using a solution of water and bleach or a specialized sump pump cleaning agent. This can help eliminate bacteria and reduce odors. Remember to follow the manufacturer’s instructions and take necessary safety precautions when using cleaning agents.

Improve Ventilation:
Ensure there is adequate airflow around the sump pump area by opening windows, using fans, or installing vents. This can help prevent moisture buildup and reduce odors.

Check for Sewage Issues:
If the odor resembles sewage, inspect the sewage system to ensure there are no blockages or malfunctions. Contact a professional plumber if necessary.

If the smell persists or if you’re unsure about the cause, it’s recommended to consult a professional plumber or sump pump specialist for a thorough inspection and appropriate solutions.
