About RainBank®. The easy way to save water Congratulations on your purchase of a high quality Australian made Davey RainBank® automatic water controller. RainBank® is patented and has been fitted to thousands of Australian homes. • RainBank® allows you to use water from your rainwater tank for your toilet, washing machine or garden whenever there is water in the tank. • If the tank water is exhausted RainBank® automatically and seamlessly switches you over to mains water.
How RainBank® works 1. When there is demand for water from your toilet, washing machine or garden tap, RainBank® senses this demand and checks the level of water in the rainwater tank. Note: demand must be greater than 1.5 litres per minute or mains water will be delivered. 2. If there is rainwater in the tank RainBank® switches on the pump. The pressure of the pump is sufficient to overcome the pressure of the mains water inside RainBank® and this moves a plunger and allows the rainwater to flow.
Before you start ! 6 IMPORTANT: • RainBank® must be installed and serviced by a licensed plumber. • Check with your local water authority on water restrictions when your rainwater tank is connected to mains water. • Do not enter a empty rainwater tank - they may contain hazardous gases. • Before installing RainBank® please read all instructions carefully as failures caused by incorrect installation are not covered under warranty.
• All pipe work and fittings should be labelled in accordance with local standards such as Australian Standard AS/NZS 3500. This standard requires that all pipework containing rainwater is marked with green ‘rainwater’ tape or stickers at 1 meter intervals and every outlet that may deliver rainwater is to be permanently signed with ‘Rain Water’ signage or a green tap marked ‘RW’. • In accordance with AS/NZS 60335.2.

Testing IMPORTANT: To protect against electrical surges and lightning strike damaging RainBank® or its pump we strongly recommend the use of a suitable surge protection device and residual current devices. Test the operation of RainBank®. 1. With the mains connected and the rainwater tank empty turn on one of the taps in the laundry that feeds the washing machine or flushes the toilet. Mains water should flow normally. The pump should not turn on.
maintaining rainbank® RainBank® does not need maintenance but there are things you can do to ensure its most reliable operation. • Fit a “first flush” system that ensures the first run of dirty rainwater does not go into the tank. • Clean your gutters and first flush devices ‘Y’ strainers and filter regularly. • Remove branches that over hang your roof. • Have a strainer fitted to your rainwater tank inlet and regularly check this for leaves and twigs, etc.
