Leaves, dirt, insects, and heavy metals can easily make their way into the tank, compromising the water quality. A high-performance rainwater tank filter is essential for removing these pollutants and ensuring your harvested water is potable for drinking. Don’t take chances with untreated tank water – equip your system with the right filter for maximum purity and peace of mind.

What is the best filtration for rain water?

For comprehensive rainwater purification, a multi-stage approach is recommended. Sediment and Carbon filters are ideal for in-house use, removing impurities and improving taste for drinking water. Complementing this, a UV treatment system on the rainwater tank itself effectively neutralizes bacteria and microorganisms. Together, this rainwater tank filter setup ensures your harvested water is clean, safe, and ready for consumption. 

How do you filter rainwater into a tank?

Effectively filtering rainwater before it enters your storage tank requires a multi-step approach. First, install a mesh screen or filter at the tank inlet to capture large debris like leaves and twigs. For comprehensive rain water tank filtration, add a UV light treatment system – this uses ultraviolet radiation to neutralize bacteria and microorganisms by preventing their reproduction. Finally, consider incorporating an in-line carbon filter to remove any lingering impurities and improve the taste. This combination of mechanical filtration, UV disinfection, and activated carbon ensures your harvested rainwater is clean, safe, and ready for all household uses.

How Long Do Rainwater Filters Last?

The lifespan of a filter for rainwater tank can vary, but most high-quality rainwater tank water filters will provide 12-24 months of reliable use before needing replacement. Factors like water volume, contaminant levels, and filter type all impact longevity. Regularly inspecting and maintaining your rainwater filtration equipment is key to ensuring optimal performance and prolonging its service life.

How Often Should Rainwater Tanks Be Cleaned?

Routine cleaning is essential for maintaining the integrity of your rainwater storage tank. As a general guideline, tanks should be inspected and cleaned at least once per year. This helps remove accumulated sediment, debris, and microbial growth that can compromise water quality. More frequent cleaning may be required if the tank is heavily soiled or experiences high usage.

What Can I Put in My Water Tank to Keep it Clean?


To help maintain a clean, well-functioning rainwater tank, consider adding products like chlorine tablets or hydrogen peroxide. These act as disinfectants, killing off bacteria and algae growth. You can also use a tank cleaner solution specifically formulated for rainwater systems. Following the manufacturer’s instructions is crucial for effective and safe tank treatment.
