Common Problems With Rainwater Harvesting Tanks

20 Jan 2021


If you are thinking of investing in a rainwater harvesting tank, you may need to consider common problems which can occur if it isn’t set up properly. We rely on water for everyday tasks, so it’s important to make the right decisions when purchasing your rainwater tank.

Our expert team can help you to choose the best solution for your home and garden, along with all the accessories needed to keep it running smoothly.

However, sometimes things do go wrong, so we have outlined some common problems that could occur, with our recommended solution.

Strange smelling tank

If your rainwater harvesting tank is smelly, there may be a few reasons why. In order to solve the problem, you will need to investigate, or call an expert to service your tank. Common causes are:

  • Algae growing inside your tank – you must ensure that your tank is sealed properly, so that no sunlight is getting through.
  • A small animal has found its way in – if an animal has gotten stuck in your tank, it may have passed away and could be contributing to the smell. If this is the case, you will have to empty your tank and sterilise it thoroughly.
  • Dust and debris from the roof – if you have an above-ground tank, it’s common for debris from your roof to enter the tank. All of our tanks come with the correct filters, but if your tank is old or from another manufacturer, our team can advise you on the filters you will need to put in place.

A blockage in the system

If your rainwater harvesting system has a blockage, it can affect the flow of water to your home. There might be leaves or other debris stuck in the tank, which you will need to remove. You should also check the filter, to ensure that this isn’t full of debris.

If you still cannot find the source of the problem, we offer local call outs to solve issues with your rainwater harvesting tank. Get in touch with our maintenance team, who will be happy to help you.

The water isn’t clear

If your water isn’t clear, the system may not be operating correctly. This is likely to be due to dirty filters, dirt or debris in the tank, or dirty water entering the system by accident from another source.

Since dirty water is a sign of debris entering the tank, we would recommend cleaning the leaf filter and maintaining a routine of doing so. It may take time for the water to refresh and ‘clear up’ if it doesn’t work then you could consider a downpipe filter, and also having the tank cleaned (Note: this isn’t a service we currently provide).
