From flow rate to installation: Choosing the best pump for your rainwater tank

Recently installed a rainwater tank on your property, or potentially shopping around for one to add as an addition? No matter your intentions, these systems embrace environmental needs and help you to save hard-earned dollars on your regular bills and thats always a win. But in order to efficiently distribute this water around your property, you need a solid pumping system thats able to meet demands.

So here's exactly what you need to know about choosing one for your specific tank.

Decide what you want your pump to do

Brands and providers like Grundfos pump suppliers specifically design systems to suit various applications. This means you should use all of these features to your advantage, carefully researching what unit is best for your needs.

The best way to do this is to make sure that you know the intentions from the beginning and base your decision-making around these details. Consider what kinds of extra features you'll require and if you need the system to direct flow in a certain way.

The flow rate is the biggest key factor here. Essentially, this means the number of litres delivered per minute. Keeping these details in front of the mind will enable you to water your garden or yard effectively, without running short on distance or distribution.

Know the types available

The modern market is blanketed with options for pumping solutions. And that can sometimes make the purchase decision stage difficult to get through. Here are the most common models you'll come across:

  • Submersible: Installed inside the tank, these units are usually quieter due to noise being muffled. They can be more difficult to maintain because of limited access, but they don't need frequent servicing as other options.
  • External: These sit outside the rainwater tank and can also be mounted on the ground opposite. They're accessible and easily serviced, but their noise is typically more noticeable because of this open positioning.

It's also important to understand that you will need a power source nearby to operate your unit. If you haven't got one handy, you'll need a professional to complete the installation beforehand. We do not recommend using a power extension cord to a further away PowerPoint, as these aren't always safe or protected from the elements.
