How Do You Maintain A Rainwater Tank?


Water conservation is becoming increasingly important, particularly with recent droughts and other environmental crises. Rainwater harvesting is one of those that saw a recent surge in popularity over the past few years. Many people have started seeing its potential as an alternative to water delivered by the local water authority. The process may appear basic – you collect rainwater from a downspout and use it for any purpose, including watering plants. However, rainwater collection is much more than that as it also requires continuous maintenance of the components used, including the rainwater tank.

 Here At The Local Plumber, we have some of the most experienced Melbourne plumbers who are always ready to help. Our team can help Melbourne residents with setting up their rainwater collection system, as well as with its maintenance and needed repairs.

How To Make the Most Out of a Rainwater Tank:

  • Keep gutters, screens and downpipes clean
  • Regularly clean the flush device and flow restrictor
  • Clean the tank’s inlet screen
  • Check the outlet filter, main switching device and pump regularly
  • Contact a plumber for servicing and an inspection if you suspect an issue 

How Do Rainwater Tanks Work?

Saving mother nature is not the only beneficial thing associated with rainwater harvesting. It also saves money on water bills, among other things. Rainwater collection is different from stormwater capture. Harvesting rainwater is the collection of water coming from the sky during rainfall. This rainwater is usually gathered on a collection surface before going into a tank. In contrast, stormwater capture collects water that has fallen on the ground and directs it into a nearby lake or river.

It is important to know everything you should know about this process. First, you should know about regulations covering rainwater collection. Next, your system should have the right tank size. Third, it is essential to work with an experienced and highly qualified plumber to ensure proper installation. Lastly, you should know how to properly maintain your rainwater tank and other components in the collection system.

What Are The Maintenance Needs of a Rainwater Tank?

A piece of equipment can only go far when it is regularly and properly maintained. This philosophy also applies to your rainwater tank. Failure to do routine cleaning can lead to damages that could interfere with how you collect rainwater. The following steps are a must to maintain a healthy rainwater tank:

  • Check the gutters, screens and downpipes – The gutters, screens and downpipes play a vital role in collecting rainwater. They are responsible for directing rainwater into the tank. Most of the time, these components are overlooked and not properly maintained. Our 24 hour plumbing repair experts recommend doing the following:
    • Trimming overhanging vegetation
    • Cleaning the roof gutter network
    • Removing dried leaves and other debris from the catchment area in the roof
    • Cleaning the screens and downpipes
    • Having a good quality gutter guard and downpipe screen
  • Check the flush device and flow restrictor – It is unavoidable for rainwater to come with debris. A flush device helps direct dirty water to a separate chamber where it will be filtered. Due to the dirt processed by these pieces of equipment, our emergency plumbers recommend cleaning it every three to six months, or after heavy rainfall.
  • Check the tank’s inlet screen – This piece of equipment stops leaves, debris and insects from entering the rainwater tank. It is best to clean them regularly to remove traces of the aforementioned things on this screen.
  • Check the filter – Some tanks need a filter for their outlet. If there is an outlet filter, experts recommend monitoring and cleaning it monthly. Most tanks requiring a filter come with instructions on how to maintain them.
  • Check the main switching device and pump – For those with rainwater collection systems that come with a pump and main switching device, it is a must to routinely check these pieces of equipment. The main switch device is responsible for checking the water level in the tank. When water is running low, or the pump has stopped, this switch will automatically depend on your main water supply.

Do I Need To Treat Water from My Rainwater Tank?

Disinfection is an important task when using rainwater tanks. The Department of Health Victoria recommends regular disinfection for it to be free of disease-causing microorganisms, like bacteria, viruses and protozoa. Aside from these microorganisms, rainwater could also contain lead. Filtration, ultraviolet light irradiation and chlorine disinfection are recommended approaches to ensure clean water.

How Long Does a Rainwater Tank Last?

Rainwater tanks usually last for about 25 to 40 years. However, several factors can impact this expected lifespan. The material of the tank significantly impacts how long it will last. The expected 25 to 40 years is offered by Aquaplate tanks. This tank is made from a specialised form of Colorbond sheet and is made up of thin sheet steel with colorbond colour coating on the outside. It also comes with a waterproof coating on the inside to provide corrosion protection. For other tank types, galvanised tanks usually last for a long time provided that they are not subjected to hard water.
