Rainwater Harvesting System Maintenance in Brisbane

A rainwater harvesting system for your Brisbane home is a wonderful resource in times of drought. It limits the amount of water drawn from public mains, and for some homes can even be the only source of water. Any rainwater harvesting system, however, needs maintenance to stay in top form and to prevent small problems from becoming disastrous. Water Tank Techs has offered top-notch, personalised service for over ten years to homeowners who need rainwater harvesting system maintenance for their Brisbane home.

Key Components of Your Rainwater Harvesting System in Brisbane

The rainwater harvesting system in your Brisbane home starts with the collection of rainwater from the roof and gutters. At Water Tank Techs, we recommend a minimum of three pre-tank filters. Your system functions better when the water coming in is clear, so gutter guards on the top and rain heads at the bottom of the gutter help keep large pieces of debris out. A first flush diverter ensures that the initial flow of rainwater, the one most likely to contain debris, is shunted to the side and does not enter your tank.

Just before the pump, which is usually located outside the tank, should be a Y strainer to remove additional foreign matter. This is important to protect the pump from having to work harder than necessary because dirty water is harder to pump. Finally, after the pump should come a filter, which can remove small particles. Depending on the quality of the filter, it can remove particles as small as one micron, or one millionth of a meter. A UV light guard is also recommended to prevent algae formation inside the tank from the sunlight that penetrates the tank.

Clean water from your rainwater harvesting system in Brisbane is essential to the proper performance of all your water appliances. Particle-filled water can cause leaks in the lines as well as damage to fittings and inner mechanisms.

Water Tank Cleaning Explained

We will conduct a free assessment of your rainwater harvesting system in Brisbane. One of the things we look for is sludge – the build-up of organic matter like decomposed vegetation, animal droppings, etc. While a small amount of sludge is expected and normal, large quantities can interfere with the water quality as well as the pump performance. The process of cleaning out a tank is relatively simple. In most cases, we can remove sludge with minimal water loss and then apply an optional sanitising agent. Certain tanks, like slimline and concrete tanks, may need to be drained to be adequately cleaned.

Pump Replacement

As part of our custom rainwater harvesting system maintenance program in Brisbane, Water Tank Techs will assess your pump’s performance and determine if it’s worth fixing or replacing based on its age and condition. If pump replacement is needed, we have a selection of top-quality ClayTech from Clayton Engineering pumps with innovative new features such as integrated, easy to clean filters.
