“ We have been very happy with our RainWatch filter, it is amazing how much dirt seems to come out of the rain itself not just from the roof surface and how clean it keeps our rainwater tanks”

Water is precious.

Massive amounts of clean rainwater can be harvested from our roofs, unfortunately, the rainwater becomes contaminated with pollutants. 

Contaminates such as bird droppings that settle on roofs and other pollutants that if not filtered out, are also collected in the rainwater, leaving storage tanks compromised. The RainWatch Rainwater Tank Filter System provides additional protection with our high quality 316 50 micron Stainless Steel barrier screen that keeps out mosquitoes and vermin.

Other rainwater tank filters allow harmful contaminants such as rotting organic matter into the water to be broken down over time. This results in toxins appearing in the final product.

Our pre-tank rainwater filtration system means potential contaminants are denied access to your water source from the very beginning, cutting down on the need for chemicals and additional cleaning.

If you’re using your tank as a source of drinking water, the need for a post-tank sterilisation device still remains. Our pre-tank water filter dramatically increases water purity so that, when you get to the end stage, there is less for your domestic filtration system to work through. It will also make your drinking water taste better.

PAH (polynuclear aromatic hydrocarbon) chemicals have been shown to find their way into water tanks. Exposure to these pollutants can cause skin, lung, bladder, and intestinal cancer; lung function abnormalities, chronic bronchitis, decreased immune function, nausea and vomiting.

With our pre-tank filter, you can remove these harmful pollutants before they reach storage areas and pumps, resulting in a cleaner, healthier water supply and a reduction in time and money spent on maintenance.
