Davey RainBank KRB2 Automatic Rainwater Controller for Surface Pumps
The Davey RainBank KRB2 Automatic Rainwater Controller is available from Installed Today as a supply-only rainwater harvesting controller or as a complete supply and install package in selected Brisbane and Gold Coast service areas.
Choose the controller only if you already have a licensed plumber or pump installer arranged, or check your supply and install package to confirm pump suitability, rainwater tank connection, mains water backup, pipework requirements, site access and available installation timeframes before checkout.
The Davey RainBank system is designed to automatically switch between rainwater and mains water supply. It gives priority to rainwater when available, then switches to mains water when the rainwater tank is empty or during a power outage. This makes it a practical solution for homes wanting to use stored rainwater for toilet, laundry, garden irrigation and selected rainwater harvesting applications.
About the Davey RainBank KRB2
The Davey RainBank KRB2 is an automatic rainwater harvesting controller designed for use with compatible surface pump systems. It helps manage the water source for your home by prioritising rainwater from the tank, while still allowing mains water backup when rainwater is unavailable.
RainBank is commonly used in metropolitan rainwater harvesting systems where homes are set up to use tank water for toilets, laundries, gardens or similar non-primary mains water applications. It is designed to help conserve mains water by using rainwater first whenever the tank has usable water available.
Davey RainBank technology can be mounted directly onto a compatible pump or installed on a nearby supportive wall for easier access, depending on the system setup and site requirements.

Rainwater Priority with Mains Backup

When the tank runs dry, or if there is a power interruption, the system allows mains water to supply the connected fixtures. This helps maintain water availability while still making rainwater the preferred source when conditions allow.
