  • When there is no tank water it automatically and seamlessly selects mains water supply.
  • 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.

Davey Pump and Rainbank Concrete Tank System

The Rainbank is a dual source controller, specifically designed to souce rainwater for water applications such as toilets and laundry, with automatic mains backup. It is to be installed between the water tank and mains water supply. When the tank has rainwater in it the Rainbank will automatically select the tank water and when there is no water in the tank the Rainbank will seamlessly switch to mains supply.
