How to Choose the Right Pump for Your New Rainwater Tank

If you're fed up hearing of the drought or worrying about dwindling water resources, you may have decided to take matters into your hands. You're going to install a rainwater tank, but you want to make sure that you do the job properly and take full use of this asset in the future. In this case, you need to look carefully at the type of pump that you buy and understand the various options available. What do you need to know?

Size and Capability

Firstly, understand that pumps come in various sizes and capabilities, and the first thing to decide is exactly what you want your tank to achieve. For example, do you simply want water to irrigate your lawn or to provide for all your household needs? How big is your property, how many people do you have to serve, and do they all tend to run for the bathroom or shower at a similar time?


As you can imagine, the more demand, the more sophisticated the pump. If you want something that can provide you with drinking water as well as other benefits, you need to choose a pump that has enough flow capacity to supply all of your outlets. You'll also need to buy a pump that is certified as being safe for drinking water and a device that can control the pressure effectively.

Flow Rate

Pumps are regulated according to their flow rate, which is typically measured by the number of litres of water per minute. You need to talk with your supplier to calculate your needs properly and should be generous in your assessment. After all, the last thing you want is to starve one of your household members of water when trying to take a quick shower on their way to an important appointment.


Furthermore, where are you going to put your tank? If it's going to be a long way from your home or if it's underground, you may need a self-priming pump. Further, you may want a pump that can automatically switch over from your rainwater tank to the mains supply, should the tank ever run out.

Quiet, Please

Lastly, think about whether your pump will be too noisy to either yourselves or near neighbours. In this case, you might want to think about a submersible pump instead. As the name suggests, this pump will be situated inside the tank itself and will certainly be much quieter than the alternative.

Your Choice

As you can see, there are many choices. Talk with your pump supplier and go through each option one by one.
