  • James L.April 12, 2026

    Installed this a few weeks ago and we are rapt with it. Coffee and tea taste much better, and we don’t get those hard water stains on the shower glass anymore. Excellent bit of kit.

  • DanielJanuary 20, 2026

    Great system. Does exactly what it says on the tin. Water tastes crisp.

  • Natalie FisherNovember 2, 2025

    If you are on the fence, just get it. We have an under-sink filter, but this now covers the whole house. Having the whole house filtered means washing the dishes, doing laundry, and showering all happen with pristine water. The water pressure hasn’t noticeably dropped, and the 3 stages mean the carbon block doesn’t get clogged prematurely by large sediment.

  • Tom W.August 14, 2025

    Fast shipping to regional QLD. The unit was packaged securely. Our town water out here leaves a lot to be desired and this 3-stage setup has completely softened it up and removed the odours. Top tier product.

  • OliviaMay 10, 2025

    Best purchase for our new build! So nice being able to drink straight out of the bathroom tap without it tasting like a swimming pool.

  • Ryan CooperFebruary 18, 2025

    I thought our town water was fine until I saw what the first stage sediment filter caught after just two months. It is terrifying what comes through the town pipes. Knowing my family is drinking clean, purified water gives me incredible peace of mind.

  • Emma C.December 5, 2024

    Solid build quality. The mounting bracket is heavy duty and holds the three housings securely. Changing the cartridges is easy enough with the provided spanner.

  • MattSeptember 30, 2024

    Saves us an absolute fortune on Brita filters and plastic bottles. The water from every tap in the house is perfect.

  • Jessica ReidJuly 22, 2024

    Brilliant. Had my plumber mate install it on the side of the house. Flow rate has not dropped at all, which was my biggest worry. Five stars.

  • Ben T.May 8, 2024

    My partner suffers from dry skin, and we read that filtering out the chlorine from town water can help. It has made a massive difference. We do not need to buy bottled water anymore either.

  • ChloeFebruary 15, 2024

    Works exactly as described. Water is crystal clear.

  • David GallagherNovember 20, 2023

    I did a lot of research before pulling the trigger on a whole house system. Living in an older suburb, our town water often has a slightly brownish tint after heavy rain. This 3-stage filter caught it all. The sediment filter does the heavy lifting, and the carbon block completely eliminates the chemical flavour. Installation was straightforward for my local plumber. Great investment.

  • Sarah M.September 4, 2023

    We mainly bought this to protect our appliances from sediment and scale, but the bonus is that our tap water actually tastes great now. Really happy with the 3-stage setup.

  • LachlanJune 12, 2023

    Mate, the difference is night and day. No more chlorine smell when I have a shower. Highly recommend.

Integrating a bypass valve is a crucial component of any whole house water filtration system.

This feature allows you to temporarily reroute untreated water around the filter for tasks that don’t require purification, such as washing vehicles, irrigating the lawn, or filling a swimming pool.

By utilising unfiltered water for these outdoor chores, you prevent unnecessary wear on your equipment and significantly extend the lifespan of your filter cartridges.

Ultimately, a bypass valve maximises your system’s efficiency, preserves its longevity, and simplifies how you manage your home’s water usage.
