How often do you think about the water that’s being drained away from your property? Probably not until there’s a problem. Drainage pumps are crucial in water management, quietly working behind the scenes to prevent flooding, manage waste, and protect the structural integrity of homes and businesses.
With various types available, each pump serves a unique purpose, from removing excess water in flooded areas to handling sewage and other waste water. Choosing the right pump involves considering factors like the application, flow rate, and head pressure it can handle.
This blog post will guide you through the different types of drainage pumps, highlighting their uses, benefits, and limitations, to help you get the right drainage pump for your specific needs.
What are Drainage Pumps?
Drainage pumps are essential tools designed for efficiently moving water from one location to another, primarily to remove excess or unwanted water from areas prone to flooding or accumulation. These devices play a critical role in preventing water damage to buildings, infrastructure, and landscapes.
They come in various types, each customised to specific environments and challenges, such as submersible pumps for flooded areas, sump pumps for basements, and sewage pumps for wastewater management.
By utilising the power of drainage pumps, property owners can safeguard their investments against water-related issues, ensuring a dry and secure environment. Their functionality spans across residential, commercial, and agricultural domains, highlighting their versatility and indispensability in water management strategies.
What Are The Different Types of Drainage Pumps?
Here are some different types of drainage pumps:
Submersible Drainage Pumps
Submersible drainage pumps are engineered to operate while fully immersed in water. They utilise a hermetically sealed motor close-coupled to the pump body, ensuring efficient water removal directly from the source. Common uses include removing water from flooded areas, draining swimming pools, and emptying ponds or tanks.
Advantages of submersible pumps include their quiet operation, high efficiency, and ability to handle large volumes of water. However, their limitations may include the need for regular maintenance to prevent motor failure due to water infiltration.
Pedestal Drainage Pumps
Pedestal drainage pumps feature a design where the motor is mounted above the water level, connected via a long shaft to the pump that sits in the water. This configuration keeps the motor dry and accessible for maintenance. Typical applications include use in basements to manage water intrusion.
Compared to submersible pumps, pedestal pumps are easier to repair and may have a longer lifespan, but they might not be as efficient in heavy-duty applications due to their lower immersion level.
Sump Pumps
Sump pumps are specialised pumps placed in a sump pit, designed to remove accumulated water, preventing flooding. There are two main types: submersible and pedestal. Submersible sump pumps are quieter and less intrusive, while pedestal pumps are easier to maintain and typically have a longer life.
Use cases span residential basements, commercial buildings, and industrial settings where water ingress is a concern. Their dependence on a power source, which may fail during storms or power outages, potentially leading to flooding.
Sewage Pumps
Sewage pumps are tasked with transporting waste water from bathrooms, laundry rooms, and kitchens to a septic tank or sewer system. They are capable of handling solids, distinguishing them from other drainage pumps. When selecting a sewage pump, consider its solid handling capability and the lift requirement to ensure efficient waste management.
Differences from other pumps include their durable design and higher power to move semi-solid and solid waste materials. However, they may require more frequent maintenance due to the harsh nature of the materials they pump.
Utility Pumps
Utility pumps are known for their portability and versatility, used for a range of water transfer tasks. Applications include garden irrigation, draining water heaters, and temporary water transfer for construction sites. When choosing a utility pump, it’s essential to consider the volume of water to be moved and the pump’s portability.
They offer the advantage of being easily moved and used across various settings, though they may not be suitable for large-scale or continuous operations. Generally lower power compared to more permanently installed pumps, potentially limiting their effectiveness in large-scale applications.
High-Head Drainage Pumps
High-head drainage pumps specialise in moving water over long distances or to high elevations, essential in agriculture for irrigation or in industrial settings for process water management. These pumps are designed for high-pressure applications, enabling them to transport water efficiently across extensive areas.
While they offer the benefit of versatile application use, they may require more power and potentially more maintenance due to the high pressures involved. Their limitation includes the need for more significant energy consumption and potentially higher initial investment costs.
How Do You Maintain Your Drainage Pumps?
Proper maintenance of your drainage pumps is crucial for ensuring their efficient operation and longevity. Here are key aspects to consider:
Regular Cleaning
One of the most important maintenance tasks is keeping your pump and its surrounding area clean. For submersible pumps, this means checking for and removing any debris that might clog the intake or impede the motor’s operation. For external pumps, ensure that the area around the pump is clear of debris and that vents and air intakes are clean to prevent overheating.
Inspecting Components
Regularly inspect your pump’s components for signs of wear or damage. This includes checking the power cord for frays, the housing for cracks, and the impeller for blockages or damage. For pedestal and sump pumps, also check the condition of the stand and the float mechanism to ensure they’re operating correctly.
Testing the Pump Regularly
Testing your pump regularly, especially before the rainy season, ensures it operates correctly when needed. For sump pumps, this can be as simple as pouring water into the sump pit to trigger the pump. For other types, running a quick operational test can help identify any issues before they become serious problems.
Professional Servicing
While many maintenance tasks can be handled by the pump owner, certain aspects of pump care, such as internal inspections, seal replacements, or motor servicing, should be performed by a professional. Scheduling an annual check-up with a licensed technician can help catch issues that might not be visible.
Conclusion
To wrap up, different types of drainage pumps, including submersible, pedestal, sump, sewage, utility, and high-head pumps, each serve a unique purpose, from removing floodwater to handling sewage. It’s key to understand their roles and how to maintain them to prevent water damage. Regular maintenance like cleaning and inspections keeps them working well.

Frequently Asked Questions
What applications require the use of high-head drainage pumps?
High-head drainage pumps are used when water needs to be moved over long distances or to high elevations, such as in agricultural irrigation or industrial processes.
How often should drainage pumps be maintained?
Maintenance frequency can vary depending on the type of pump and its usage, but it’s generally recommended to check and clean your pump at least annually or more frequently in areas with high water volume.
What is the best drainage pump for flood prevention?
Submersible pumps are typically the best choice for flood prevention due to their ability to operate underwater and handle large volumes of water efficiently.
Do all drainage pumps handle solids?
Not all drainage pumps are designed to handle solids. Sewage pumps are specifically designed to handle waste water with solids, whereas other types, like sump and utility pumps, are meant for clear water applications.
How do I know which type of drainage pump I need?
Choosing the right drainage pump depends on the specific needs of the application, such as the volume of water to be moved, whether solids are present, and the distance or height the water needs to be transported. Consulting with a professional can help determine the best type for your situation.
Can I install a drainage pump myself?
While some drainage pumps can be installed by the homeowner, such as certain submersible or utility pumps, it’s often best to consult with or hire a professional for more complex installations, like sewage or sump pumps, to ensure proper setup and operation.
