Australian Consumer Law

Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure.

By filtering at the mains entry point, the K-T-WH20S supports water quality across the household rather than serving only one kitchen tap. This makes it appealing for homes seeking filtered water for drinking and food preparation as well as bathing, laundry and other everyday water uses.

Filter performance and cartridge life depend on incoming water quality, pressure, flow and household demand. The system should therefore be installed where it remains easy to isolate, inspect and service, with replacement cartridges selected to suit the desired filtration function and local water conditions.
