There is no re-pumping of mains water supply.

Provides seamless mains backup in the event of no rainwater or electrical interruptions, for convenience and comfort.

• When it rains and the tank refills the Rainbank automaticallyand seamlessly changes back to tank water supply.
• The Rainbank automatically switches between rainwater and mains water supply with lights on top indicating which one is in use.
