Rainwater tanks can collect leaves, dust, pollen, roof debris and other particulates that affect the appearance, taste and overall quality of your water. This system is designed to filter the water supplied throughout your home, providing filtered water at every tap.
Water passes two filtration stages before entering your home’s plumbing.
Designed for smaller households, the high-flow design allows up to three taps to operate simultaneously without a noticeable loss of pressure.
For best performance, the connected pump should deliver between 20 psi (138 kPa) and 125 psi (862 kPa).
Stage 1 – Sediment Filter 10 μm
Reduces dirt, dust, rust and other suspended particulates, helping protect the cartridges that follow. For most rainwater applications, we recommend replacing the sediment cartridge every 6–8 months, depending on water quality and household usage.
Stage 2 – Carbon Silver 0.5 μm Bacteriostatic
This activated carbon silver cartridge contains silver as a bacteriostatic agent to help inhibit bacterial growth within the filter media. It also assists in reducing VOCs, herbicides, pesticides and a range of organic compounds.
Every rainwater supply is different. The amount of sediment and organic matter entering your tank depends on factors such as your roof, gutters, surrounding vegetation and maintenance practices.
Installation by a licensed plumber is recommended.
We recommend installing a bypass valve, allowing the filtration system to be isolated during maintenance without interrupting the household water supply.
Installation is not included in the listed price.
If you’re located in Perth, we can arrange installation through one of our trusted licensed plumbing partners. Contact us for an installation-inclusive quotation.
The filter system can be installed either at the water tank after the pump or where the water enters your home, supplying filtered water throughout the house. In the situation of having the UV sterilisation unit, power is required, after the filter.
To maintain filtration performance, we generally recommend:
Replacement frequency will vary depending on water quality and household usage.
If your rainwater is collected from a roof and stored in a tank, filtration removes particulates and helps improve the taste and appearance of the water. However, filtration alone is not designed to disinfect rainwater.
This cartridge combination helps inhibit microbial growth but does not remove bacteria or microorganisms. DO NOT USE with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
If there is any possibility the water may contain bacteria or other microorganisms, we recommend adding a suitably sized UV sterilisation system.

Rob and Mavis have been great service to me and my new home (which I had to suffer and wait for ~4years to get house completed). They are excellent in providing advice that are practical and pragmatic. Please, I cannot promote them further. have a 3-stage full house water filter system, and I love it. and I agree with them, “It is a MUST”.

We installed the whole house water system last year and it has helped us remove water contaminants like rust. It has also saved some of our house hold appliances like kettle that always had calcium.
