The Dangers of Not Maintaining Your Rainwater Tank

When it comes to rain water, there’s a common misconception that this may be maintenance free. However, the truth is no part of your home is maintenance free. The most common issue with rainwater tank systems is not that they need maintenance or repairs, but more so, no one has informed the home owner that they do need maintenance.

Through failing to maintain the tank, the amount of sludge that builds up at the bottom of a tank becomes a silent killer. The sludge can promote and accelerate rust in steel tanks, and can cause problems with pumps and accessories in poly tanks as well. No tank system is immune from this problem of sludge build up and every tank needs maintenance.

Through regular maintenance, you’re protecting your tank from a build up of outdoor elements. So this doesn’t quickly transition into a breeding ground for bacteria, algae and mosquitoes. And more so, doesn’t contribute to the breakdown of a pump system. The desludging and cleaning of tank systems prolongs the life of the complete system.

Find yourself searching, “How to clean a rainwater tank?” The truth is, caring for your rain water tank doesn’t have to be tricky. It’s important to look out for the core tank components for your peace of mind. Providing a smooth rain water harvesting experience, from start to finish.

See how below:

Roof and Gutter Cleaning

Before rain reaches your tank, it touches your gutter and roof. Which then makes this surface the first point of potential contamination. Dirty roofs and clogged gutters send dust to the tank which forms a thick layer of sludge in the tank system..

It’s important to trim overhanging branches, sweep off leaves, and clear any blockages in your gutter system. This not only improves water quality but also reduces pressure on your downpipes and pump. Professional gutter cleaning can also help, along with stormwater system maintenance.

Rethink Your First Flush

A first flush diverter is a device that prevents the dirtiest portion of rainwater from reaching your tank. This water often contains the most debris, including dust and droppings that build up between rains. New homes should come with a first flush device fitted on a tank system, and these require regular maintenance. A tank system can be deemed non compliant without one, but in practical terms, sometimes a tank could even be better off without one.

Through deterring the initial runoff, this reduces the amount of sediment reaching the tank system One key step is ensuring that the water is drained properly to remove these hazards. It’s important to flush out this device once every few months. This then reduces the sediment build up, but can never eliminate it.

Inspect Rain Water Tank Filters and Inlet Screen

Did you know that tank filters and screens play an essential role? These prevent the entry of contaminants into the system, which is why its key to maintain these components. This then ensures that these can operate as smoothly as possible.

Take the time to inspect and clean your filter cartridge every 3-6 months. However, it’s important to note that this can vary based on the amount of rainfall in your region. On the other hand, the tank inlet screen should also be inspected and cleaned 1-3 months. Through regular cleaning, you’re preventing the build up of debris and other outdoor elements. If you notice that your tank screen or filter basket has a hole in it because the original installer put a pipe through it for your pump system, get in touch with us immediately. This is not normal and can damage the pump system through a rapid build up of sludge and debris which can break a pump system.

Prevent the Build-Up of Tank Sludge

Even with great filtration, fine particles and organic matter will eventually settle at the bottom of your tank. These contaminants include but aren’t limited to sediment, dirt and other waste. The formation of this sludge over time can gradually affect the quality of the water, causing odours. Which is why it’s important to schedule an annual clean with a professional.

To ensure that rain water is flowing to taps, and other appliances it’s key to maintain this regularly. Contact a professional for annual pump maintenance, or if you notice signs such as unusual noises from the pump, or loss of pressure and water volume..
