Features & Benefits

  • Automatically switches between rainwater and mains water, ensuring reliable supply          
  • Save water by using rainwater to flush toilets, wash clothes and water gardens
  • Provides seamless mains backup in the event of an empty rainwater tank or electrical interruptions
  • Saves energy by not repumping mains water and uses no power in standby mode
  • Built-in back flow prevention 'dual check' valve for added safety
  • RainBank and controller can be mounted on the pump or a nearby wall, up to 9 metres from tank

How RainBank works - 
When an appliance like a toilet or washing machine is being filled, RainBank detects the water beginning to flow along the pipes and pumps rainwater if it is available - effectively switching the water source from the domestic mains to the rainwater supply.
If the rainwater supply is exhausted, RainBank switches off the pump and allows mains water to flow.
