Whether it’s the sounds and movement of the ocean, a fast flowing brook or a spectacular waterfall, there is something about the sound and motion of moving water that soothes and calms. And while few of us have the luxury of a private, brook, waterfall or ocean front home, we can certainly have a beautiful water feature in the form of a fountain!
A well-functioning fountain enhances any outdoor or indoor space, creating a soothing ambiance with the sound of flowing water. The key to maintaining a beautiful and efficient fountain lies in selecting the right pump.

Choosing the Right Fountain Pump for Your Water Feature
There are two types of fountain pumps for homeowners to choose between – submersible and external pumps. Each type offers unique benefits. Understanding the differences helps in making an informed decision based on specific needs.
What is a Fountain Pump?
A fountain pump circulates water through a fountain, keeping it fresh while preventing stagnation. It ensures continuous movement, which helps oxygenate the water and reduce algae growth. The right pump also enhances the aesthetic appeal of a fountain by controlling water flow and pressure.
Fountain pumps fall into two main categories:
- Submersible pumps, which sit directly in the water.
- External pumps, which remain outside the fountain while drawing water through a connected system.
Each type serves different purposes, making it essential to assess the specific requirements of your fountain before selecting a pump.
Understanding Submersible Fountain Pumps
How Submersible Pumps Work
Submersible pumps operate entirely underwater, typically sitting at the base of a fountain or pond. They pull in water and push it through a nozzle or tubing, creating a steady and controlled flow. These pumps are self-contained, requiring only an electrical connection to function efficiently.
Benefits of Submersible Pumps
1. Easy Installation
Submersible pumps are simple to install, requiring minimal setup. Since they sit directly in the water, they do not require complex plumbing or external piping. Most models include a plug-and-play design, making them a popular choice for DIY enthusiasts.
2. Quiet Operation
Because submersible pumps operate underwater, they produce little to no noise. The surrounding water dampens vibrations, making these pumps ideal for fountains in peaceful gardens, patios, or indoor settings where a quiet ambiance is essential.
3. Space-Saving Design
Unlike external pumps, submersible models do not require additional space outside the fountain. This makes them perfect for compact water features, such as small backyard fountains, decorative birdbaths, or indoor tabletop setups.
4. Energy Efficiency for Smaller Fountains
For small to medium-sized fountains, submersible pumps consume less energy while delivering an adequate water flow. Many models are designed to be energy-efficient, reducing long-term electricity costs.
Potential Drawbacks of Submersible Pumps
- Limited Power for Large Fountains – Submersible pumps work best for smaller setups. They may struggle to provide adequate water circulation for large or multi-tiered fountains.
- Regular Maintenance Required – Because they remain submerged, these pumps need frequent cleaning to prevent debris buildup.
Understanding External Fountain Pumps
How External Pumps Work
External pumps, also known as out-of-pond pumps, remain outside the fountain or water feature while drawing water through an intake system. These pumps are often more powerful and can handle higher water volumes, making them suitable for larger fountains or pond systems.
Benefits of External Pumps
1. Ideal for Large Fountains
External pumps provide higher water flow rates and stronger pressure, making them perfect for expansive fountains, cascading waterfalls, or multi-level water features. Their robust performance ensures an even and consistent flow across large areas.
2. Longer Lifespan
Since external pumps do not stay submerged, they are less prone to corrosion and wear caused by constant water exposure. This often results in a longer lifespan compared to submersible pumps.
3. Easier Maintenance and Repairs
Positioned outside the water, external pumps are more accessible for cleaning and repairs. There is no need to remove them from a pond or fountain, simplifying maintenance tasks.
4. Energy Efficiency for High-Volume Systems
While submersible pumps are efficient for smaller fountains, external pumps offer better energy efficiency for larger-scale water features. Their design allows for optimal energy use while managing higher water flow demands.
Potential Drawbacks of External Pumps
- Requires More Space – These pumps need installation outside the fountain, which may not be ideal for compact garden spaces.
- Higher Initial Cost – External pumps often have a higher upfront cost due to their powerful performance and durability.
- More Complex Installation – Setting up an external pump requires additional plumbing and proper placement to ensure efficient operation.
Comparing Submersible and External Pumps: Which One is Best for You?
Best Choice for Small to Medium Fountains
- Go with a submersible pump if space is limited and ease of installation is a priority.
- They work best in indoor fountains, birdbaths, and small decorative water features.
- Quiet operation makes them suitable for peaceful gardens and patio setups.
Best Choice for Large or High-Performance Fountains
- Choose an external pump for large fountains, ponds, or waterfalls that require powerful water circulation.
- They provide better long-term durability and efficiency for heavy-duty water features.
- Ideal for homeowners who need easy maintenance access without removing a pump from the water.
Energy Efficiency Considerations
- Submersible pumps are more efficient for low-volume applications, consuming less energy for small fountains.
- External pumps are better suited for larger water systems where higher flow rates justify the energy use.
Making the Right Choice for Your Fountain
Selecting the right pump depends on your specific fountain setup. If ease of installation, quiet performance, and compact design are essential, a submersible pump is the best option. However, if you need a powerful, long-lasting, and efficient solution for a large fountain, an external pump offers better reliability.
While many local hardware stores stock pumps, they usually lack both range and the technical knowledge to guide buying decisions. Specialist fountain pump suppliers offer a comprehensive range of high-quality submersible and external fountain pumps. Their selection ensures you find the right pump, at the right price, to suit your water feature’s needs while maintaining efficiency and performance.
Conclusion
Fountain pumps play a crucial role in maintaining water movement and aesthetic appeal. Whether choosing a submersible pump for its ease of use and compact design or an external pump for its power and longevity, selecting the right model ensures a smooth and efficient fountain system. By considering your fountain’s size, maintenance preferences, and energy efficiency needs, you can invest in the best pump for long-term performance. No matter which type you choose, maintaining a well-functioning pump keeps your fountain looking beautiful and operating at its best for years to come.
