Thank you all for your support. 😊 Yes, we can deliver to you WORLDWIDE and our website provides freight options.

Doust Plumbing Products was the first to offer pre-tank rainwater filtration. This setup, shown on our page is one of our overseas installations, prevents customers from drinking unpleasant rainwater—a common challenge worldwide. RainWatch Filters come with a 5-year Guarantee. A leading water filtration expert carried out the installation in conditions similar to those found globally, especially on islands. Reliable filtration and expert-endorsed performance ensure customers enjoy safe, high-quality water for years.

On this island, we have a bank of six RainWatch Filters. You can connect them in a similar setup, scaling from 90mm to 150mm based on your roof area. Properly sizing RainWatch Filters ensures effective filtration and optimum performance, as detailed in our installation manual.

The retail price is $795 AUD plus freight. The RainWatch Filter comes in a box measuring 52 x 16 x 61 cm and weighing 8 kg. We usually ship the same day.
Instructional and demonstration videos are available on our page.
