The RAINSAVER MK4E is an evolutionary change in our range of Bianco Rainsaver devices that switches seamlessly between tank water and the mains supply. Not only does it conserve water, it’s easy to install. Not to mention, each control carries a peace-of-mind 2 Year Infield Warranty (Australia only) and is WaterMark approved. The Bianco Rainsaver MK4E is Australian owned and designed so you know it’s ideal for Australian and New Zealand home owners.
