The Davey RainBank automatically switches between rainwater and mains water supply, so there is no need for consumer intervention. The Rainbank is a dual source controller, specifically
designed to source rainwater for water applications such as toilets, exterior taps, and/or laundry, with automatic mains water back-up. The Davey RainBank systems are ideal for metropolitan
rainwater harvesting on homes, toilet blocks and garden irrigation. Duty: 40 litres per minute at 200kPa.
