The key to creating a water feature that truly captivates lies in the thoughtful selection of submersible pumps. These specialised pumps, designed to operate underwater, provide the necessary power and control to achieve the perfect flow and aesthetic effect. Submersible water feature pumps will transform your water feature into a mesmerising masterpiece.

Understanding the Role of Submersible Pumps:


Submersible pumps are engineered to operate submerged in water, ensuring a seamless integration into your water feature. Unlike external pumps that require complicated plumbing and unsightly pipes, submersible pumps work discreetly beneath the water’s surface. They draw water through an intake, effectively creating a closed-loop system that keeps the water circulating. This constant circulation not only enhances the visual appeal but also promotes water aeration, maintaining the health and vitality of any aquatic life present. Maintenance is also lower on submersible pumps as the water works to keep the pump cool, reducing stress and strain on the pump.


Choosing the Right Submersible Water Feature Pump:


Selecting the appropriate submersible pump is vital to achieving the desired flow and aesthetic effect in your water feature. Consider the specific requirements of your project, such as the volume of water, desired flow rate, and the vertical distance the water needs to be lifted (known as head pressure). By carefully assessing these factors, you can choose between different types of submersible water feature pumps available in the market, such as a centrifugal pump or an axial-flow pump.


Centrifugal pumps are commonly used for small to medium-sized water features. They operate by converting the rotational energy of an impeller into kinetic energy, effectively propelling water through the pump and out into your feature. Centrifugal pumps are known for their efficiency and reliability, making them a popular choice among homeowners and landscape designers alike.


For larger water features with higher water volumes, axial-flow pumps are more suitable. These pumps employ a different mechanism, utilising the propeller-like action of their impellers to move water in a more linear direction. Axial-flow pumps are known for their ability to move substantial amounts of water efficiently, making them ideal for grand fountains or cascading waterfalls.


Planning the Layout:


To maximise the visual impact of your water feature, careful planning of the layout is the key to success. Consider the overall design aesthetic and the desired interaction of water with surrounding elements. Will the water flow gently over rocks, creating a tranquil stream? Or will it shoot upwards in a dramatic fountain display? Visualise how different water flow patterns and heights will complement the existing landscape, hardscape, and architectural features. Remember too, a water feature isn’t just about the visual aesthetics, the sound of moving water is an important, and soothing, component.


When designing the layout, also take into account the practical aspects of installation and maintenance. Accessibility for future cleaning and potential pump servicing should be considered. Creating access points and incorporating easy-to-remove components will save you time and effort in the long run.


Proper Installation:


Once the layout of your pond or feature is finalised, it’s time to install your submersible pump. For maximum water circulation select a spot away from the fountain or cascade that is in the deepest possible water. If your pond base has pebbles or gravel then clear this back so that the pump can sit on the pond base, reducing vibration. If you have pond plants ensure they are clear of the pump intake.

Most pumps will come with an onboard pre-filter sponge however if you want to improve water flow and reduce maintenance swap this out for a larger external pre-filter block. You may also wish to consider an external in-line filter unit.


Next, carefully connect the tubing and associated plumbing to your pump that will allow you to run your outlets. You’ll find flexible anti-kink tubing makes this very simple.


Finally, run the power cord and connect to power before switching on. Your pump and the fountain or cascade may take a minute or two to fill and develop pressure on their first run so don’t panic when flow isn’t instantaneous.


When connecting to power ensure that you comply with all required regulations and that mains power electrical work, such as adding an outdoor powerpoint, is conducted by a licensed electrician. 


Harnessing Technology:


Advancements in submersible pump technology have opened up a world of possibilities for water feature enthusiasts. Many modern pumps come equipped with variable flow controllers, allowing you to adjust the water flow rate to suit different preferences or create specific water effects. This versatility enables you to set a gentle trickle for a soothing ambiance or dial up the flow for a more energetic display during special occasions or gatherings.


Maintenance and Care:


To ensure the longevity and continued performance of your submersible pump, regular maintenance and care are essential. Over time, debris, leaves, and sediment may begin to clog the filter block, placing strain on the pump, compromising its efficiency and potentially leading to blockages. Periodically clean the filter block, external in-line filter if used and the pump components, removing any accumulated debris to maintain optimal water flow.


Inspect the pump’s power cables and connections for any signs of wear or damage regularly too. Any damaged or exposed wiring should be addressed immediately to avoid electrical hazards.
