Pond Pumps - What to Consider - Play It Koi

Pond Pumps

Ah, pond pumps. The unsung heroes of the backyard water feature world. Sure, they may not be as flashy as a fountain or as peaceful as a koi fish, but without them, your beloved pond would be nothing but a stagnant pool of algae and mosquitoes.

So, what exactly is a pond pump? Well, in layman's terms, it's a device that moves water from your pond to your filtration system and back again. It's basically the circulatory system of your backyard oasis, ensuring that everything stays clean and healthy.

But not all pond pumps are created equal. There are submersible pumps, external pumps, and even solar-powered pumps (for the environmentally conscious among us). And don't even get me started on the different flow rates, head heights, and horsepower options.

But fear not, dear reader, for I am here to guide you through the murky waters (pun intended) of pond pump selection. First and foremost, you need to determine the size of your pond and the volume of water it holds. This will give you a baseline flow rate that your pump needs to achieve in order to properly filter the water.

Next, consider the height and distance that your pump will need to move the water. If you have a waterfall or stream in your pond, you'll need a pump with a higher head height (the maximum height that the pump can move the water) to ensure that the water flows smoothly.

And of course, don't forget about energy efficiency. A high-powered pump may seem like the way to go, but it could end up costing you a pretty penny in electricity bills. Look for pumps with a variable speed control, which allows you to adjust the flow rate to meet your needs while minimizing energy consumption.

Two Main Types

Submersible Pond Pumps: Submersible pumps, as the name suggests, are designed to be submerged in the pond water. They are typically compact, easy to install, and operate quietly. They are suitable for small to medium-sized ponds and are commonly used in backyard water features.

External Pond Pumps: External pumps, on the other hand, are installed outside the pond, typically in a nearby pump house or shed. They are generally larger and more powerful than submersible pumps, making them suitable for larger ponds or water features that require a high flow rate or head height. External pumps can be more difficult to install and maintain, but they are generally more durable and have a longer lifespan than submersible pumps.

Solar-powered pumps are becoming increasingly popular for their eco-friendliness and energy efficiency. They use solar panels to generate electricity, which powers the pump. These pumps are ideal for small to medium-sized ponds in areas with plenty of sunshine. They are quiet and low-maintenance, but they are not as powerful as submersible or external pumps and may not work well in areas with limited sunlight. Because they are not yet fully reliable, we do not recommend nor carry these pumps at Play it Koi.

Two is always better than one for pond Keeping!

If nothing else from this article, we hope you Learn from our mistakes. Sadly, we have lost hundreds of finned friends due to the lack of designing redundant pumps into a pond. Since then, we will never build a pond with just a single pump ever again. Having redundancy in pond pumps is crucial for maintaining a healthy and thriving pond environment. Redundancy refers to having two pumps instead of just one, so that if one pump fails, the other pump can continue to circulate water and oxygenate the pond, preventing fish from suffocating and dying.

Pond pumps are often subjected to harsh outdoor conditions, such as extreme temperatures and debris buildup, which can cause them to malfunction or fail. In addition, power outages and electrical storms can also cause pump failure. If you only have one pump and it fails, the water in your pond can quickly become stagnant and depleted of oxygen, which can lead to fish suffocation and death.

Having two pumps in your pond, on the other hand, provides a backup system in case one pump fails. If one pump goes out, the other pump can continue to circulate water and oxygenate the pond until the faulty pump is repaired or replaced. This can give you peace of mind knowing that your fish and other aquatic life are protected in case of a pump failure.

In addition to providing redundancy, having two pumps can also improve water circulation and filtration in your pond. By using two pumps, you can create a more efficient and effective filtration system, which can help to keep your pond water clear, clean, and healthy for your fish and aquatic plants.

In conclusion, having redundancy in pond pumps is important for ensuring the health and wellbeing of your fish and other aquatic life. By investing in a backup pump, you can prevent fish suffocation and death in case of a pump failure, while also improving water circulation and filtration in your pond.

Pond Pump Accessories

When it comes to pond pumps, there are a variety of accessories and replacement parts available to help you get the most out of your pump and keep it running smoothly.

One important accessory is a pre-filter, which attaches to the inlet of your pump and helps to prevent debris from clogging the pump impeller. This can extend the life of your pump and reduce the need for maintenance.

Another useful accessory is a check valve, which helps to prevent backflow and water hammer (a loud banging noise that can occur when the pump turns off). A check valve is particularly important if you have a waterfall or other feature that is located above the water level of your pond.

Other accessories include fountain heads, which can be attached to the outlet of your pump to create different water patterns and effects. Some fountain heads even come with LED lights, adding a beautiful nighttime element to your pond.

When it comes to replacement parts, impellers and seals are common items that may need to be replaced over time due to wear and tear. It's important to choose replacement parts that are specifically designed for your pump model to ensure proper fit and function.


How to Chose a Pond Pump?

Choosing the right pond pump is crucial for maintaining a healthy and thriving pond environment. Here are some factors to consider when selecting a pump for your pond:


  • Pond size: The size of your pond is a critical factor in determining the appropriate pump size. A general rule of thumb is to choose a pump that can circulate the entire volume of water in your pond at least once per hour. For example, if you have a 1,000-gallon pond, you would need a pump with a flow rate of at least 1,000 gallons per hour.
  • Water features: Consider any water features you may have in your pond, such as a waterfall or fountain. These features will require additional water flow, so make sure to factor that into your pump selection.
  • Head height: The head height refers to the vertical distance between the pump and the highest point of the water feature. If you have a waterfall or other feature that is located above the water level of your pond, you will need a pump with a higher head height rating.
  • Power consumption: Pond pumps can consume a significant amount of electricity, so it's important to choose a pump with an appropriate wattage for your needs. Keep in mind that higher flow rates and head heights will typically require more power.
  • Noise level: Depending on the location of your pond, noise level may be a consideration. Some pumps operate quietly, while others can be quite loud.
  • Brand and quality: Finally, consider the brand and quality of the pump. Look for a reputable brand with a history of producing high-quality and reliable pond pumps. This can help to ensure that your pump will last for years to come and require minimal maintenance.


In conclusion, pond pumps may not be the flashiest part of your backyard paradise, but they are absolutely essential to keeping your pond clean and healthy. So, choose wisely, my friends, and let the soothing sound of flowing water wash away your worries.
