A pond pump is crucial if you want to keep your garden pond healthy. The pump will circulate the water in the pond regularly to prevent stagnation and insect reproduction. Also, a pump oxygenates the water to keep any life forms alive and well. Visit your local pond supplier for advice on which pump will suit you best.
If your pond is small you may be best choosing a submersible pond pump. These are cheap and require little installation knowledge. This will be a quiet pump and can be utilized in draining the pond for maintenance if attached to a hose.
Consider how many gallons per hour the pump will circulate, GPH should be about half the size of your pond’s water volume. For instance, a pond with 150 gallons of water will require at least a 75 GPH pump.
If you would like to keep Koi or have a water feature such as a waterfall you will need to buy a bigger pump. Leave purchasing your pump until you are clear about what your pond will contain. Make sure any pump you choose is UL approved and designed for underwater outdoor use.
Your pump will be operating 365 days per year so check the energy rating of any pump you are considering, otherwise you will get a big shock when the electric bill comes. Ensure your pump has at least a two-year warranty, as this will suggest that the manufacturer has built the pump to last.
Cost doesn’t always indicate a good quality pond pump. Look for quality and reliability, as it only needs to fail once to cause devastation and loss of life. Not only this, you will have the inconvenience of having to source another pump very quickly indeed or, get your pump mended in a short space of time
