HOW RAINBANK® WORKS
1. When there is demand for water from your toilet, washing machine or garden
tap, RainBank

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
of the pump is sufcient to overcome the pressure of the mains water inside
RainBank® and this moves a plunger and allows the rainwater to ow.
Note: mains water pressure is not restricted.
3. When there is no longer a demand for water, RainBank
ceased to move inside the pipes, switches off the pump and waits for another
water demand.
4. If RainBank
rainwater tank it will automatically allow the mains water to ow.
5. If there is a power failure during a demand for water, RainBank
automatically supply the mains water as backup.

• RainBank

approved & your plumbers insurance should cover installation faults.
®
• RainBank
will provide mains water as backup when:
- there is no rainwater

- the pump has been removed for servicing. Air-gap systems rely on pumps to
pressurise all water and do not function without them.

rainwater tank is connected to mains water.
