Garden Pond Water Pump Buying Guide
Whether you have a Liner Pond or a Preformed Pond, you will most likely benefit from a Pond Water Pump – as both types of pond may.
There is a large variety of Pond Water Pumps available, however they mostly boil down to two different types; Submersible (Underwater) or External (Out of Pond).
- Submersible Pumps are generally best for the home garden with just a small pond, as they are quiet, require very little installation, and have the added benefit of being capable of draining your pond.
- External Pumps are usually for Ponds which require a large volume of water to be pumped. Therefore they are not always suitable for the home garden.
What Pump do you Need?
Before choosing a Pond Water Pump you must work out how much work you want it to do. This will be dependent on your Pond’s Size, Waterfall, Water Features and Filters.
Simply put, the more work – the more powerful the pump required.
Pumps are sized by ‘Gallons Per Hour’ (GPH).
For a healthy pond, water should be circulated once every two hours.
For example. A 100 Gallon Pond would require a 50 Gallon Per Hour Pump. (Minimum)
It’s always a good idea to choose a pump that exceeds the minimum amount of circulation required. As this will ensure it doesn’t always run at it’s capacity – and gives the potential to expand or add more features in the future.
The more features your pond has and the higher the waterfall, the more powerful a pump you will need.
Formula for working out the size of your pond in gallons
If you have a square or rectangular pond:
Length x Width x Average Depth x 7.5 = Total US Gallons (x1000 for Litres)
If you have a round pond:
(0.785 x Top Diameter x Bottom Diameter x Depth) x 7.5 = Total US Gallons Radius x Radius x 3.142 x Depth x 1000 = Total Litres
Installation and Servicing Your Garden Pond Pump
It is important to make sure your Pump is located in an accessible place, around the side of your Pond, also ensure that it is not too deep.
This will make it nice and easy to install and maintain, and also reduce the risk of slips and falls.
