Pond Pump FAQs
Pond pumps are designed to move, circulate, and flow water around your pond, helping to push it through your filter system, oxygenate the water, and prevent any issues that may arise from stagnant water.
Natural pools will have a stream of water, whereas your garden pond does not – meaning they can become stagnant and unhealthy. A pond pump simulates this flow of water to prevent any issues for your garden pond, while also disturbing the water and introducing more oxygen.
How Do Pond Pumps Work?
Pond pumps are simple devices:
- They draw water in through an intake strainer.
- The water then passes through an impeller, which is a rotating part that creates pressure.
- This pressure forces the water out through an outlet, which is connected to a hose or pipe.
- The water is then delivered to a filter, waterfall, or fountain, depending on your setup.
The process creates a continuous cycle, ensuring the entire volume of your pond is regularly circulated.
Benefits of a Pond Pump
While some pond plants do add oxygen, they provide a limited amount compared to the circulation created by a pond pump. The benefits of a pond pump include:
- Balancing the Eco-System: Pumps help maintain a stable, healthy environment for fish and plants.
- Effective Filtration: They push water through your pond's filter, removing debris and waste to keep the water clean and clear.
- Oxygenation: Continuous water movement infuses the water with oxygen, which is vital for the health of your fish and beneficial bacteria.
How To Choose a Pond Pump
The options of pond pumps can seem overwhelming, so you might be wondering where to start on choosing the right pump for your garden pond. Different factors, such as the size of your pond, whether you have water features, and the type of filter system you have, can affect the type of pond pump you need.
Types of Pond Pumps
Submersible Pond Pumps: Most pond pumps are designed to be submersible, meaning they operate within the pond water. They are ideal for smaller ponds due to their compact, out-of-sight design. Submersible pumps are quiet, easy to install, and can effectively circulate water in small- to medium-sized ponds.
External Pond Pumps: These pumps are located outside the pond and are better suited for larger ponds or more complex systems. They are designed to move large volumes of water and are often more expensive up front. A key advantage of external pumps is that they are easier to maintain, as they are not submerged.
Filter Pumps: This is the primary pump for any pond. A filter pump is designed to run 24/7, pushing pond water through your filter system. These pumps can handle solid waste and debris, ensuring your pond water stays clean. It's important to consider the running costs, as they operate continuously.
All-in-One Pond Pumps: These units combine a pump and filter into one compact device. They are perfect for small, pre-formed ponds and container ponds, offering a convenient solution that saves space and simplifies setup.
Fountain Pumps: Fountain pumps help to push pond water in two directions; this can be to a filter and a fountain feature. They are designed for clean water and can clog easily with solid debris, so they are not suitable for driving a pond's main filter.
Water Feature Pump: Water features also require water to be circulated through them. Water feature pumps can only handle a small amount of water and, as a water feature is not expected to have much waste within it, they also cannot help in filtering out solids from the water.

What Size Pond Pump Do I Need?
The correct pump size is critical for a healthy pond. Generally speaking, those with smaller ponds are better off looking at submersible pond pump choices, while those with larger ponds should consider external pond pumps. A pump that is too small won't circulate the water effectively, while one that is too large can be inefficient and costly to run.
Pond Pump FAQs
How many hours a day should I run my pond pump?
A pond pump should run 24 hours a day, 7 days a week, from spring to late autumn. This ensures continuous filtration and oxygenation. The only time you should consider turning it off is during the depths of winter if the water surface is completely frozen over. Learn more in our guide on Should I keep my pond pump running in winter?
When do I turn my pond pump back on?
In the spring, you should turn your pond pump back on as soon as the risk of freezing temperatures has passed. This is usually when the water temperature starts to rise and before fish become active again.
What pond pump do I need?
The type of pump you need depends on your setup. A filter pump is essential for continuous filtration, while an all-in-one unit is great for smaller ponds. If you have a waterfall or fountain, you'll need a pump with enough power to handle the head height. Our team can help you select the ideal solution.
