Davey RainBank KRBS2 Submersible Rainwater Pump System
The Davey RainBank KRBS2 Submersible Rainwater Pump System is available from Installed Today as a supply-only rainwater harvesting system or as a complete supply and install package in selected Brisbane and Gold Coast service areas.
Choose the system only if you already have a licensed plumber or pump installer arranged, or check your supply and install package to confirm tank suitability, pump access, mains water backup, pipework requirements, site access and available installation timeframes before checkout.
The Davey RainBank KRBS2 is designed to automatically switch between rainwater and mains water, giving priority to rainwater when available and switching to mains water when the tank is empty or during power interruption. This makes it a practical option for homes wanting to use stored rainwater for toilets, laundry, garden irrigation and selected rainwater harvesting applications.
About the Davey RainBank KRBS2
The Davey RainBank KRBS2 is a submersible RainBank system designed for domestic rainwater harvesting applications. It combines Davey RainBank automatic mains/tank water switching technology with a submersible pump package, making it suitable for selected homes where the pump is located inside the rainwater tank.
RainBank gives priority to rainwater when tank water is available. When the tank runs dry or power is interrupted, the system allows mains water to supply the connected fixtures. This helps maintain water availability while reducing unnecessary mains water use where rainwater is available.
The KRBS2 is commonly used for toilets, laundry connections, garden irrigation and rainwater-to-mains backup systems. It is especially useful where a submersible pump setup is preferred over a surface-mounted pump, helping reduce above-ground pump noise and keeping the pump inside the tank.

Is the Davey RainBank KRBS2 Right for Your Property?
The Davey RainBank KRBS2 may be suitable if your home has a rainwater tank and you want automatic switching between rainwater and mains water for selected fixtures.
It is commonly used where rainwater is intended for toilets, laundry connections, garden irrigation or other approved rainwater harvesting applications. The system gives rainwater priority when available, then switches to mains water backup when required.

You want rainwater to be used before mains water

-
The system is being moved to a new location
-
Existing pipework is undersized, damaged or unsuitable
-
Extra fittings, valves or unions are required

Rainwater Priority with Mains Backup
The Davey RainBank KRBS2 is designed to use rainwater first when tank water is available. When a connected fixture needs water, the system prioritises rainwater from the tank.
If the tank is empty, or if there is a power interruption, the system allows mains water to supply the connected fixtures. This helps maintain reliable water availability while still using stored rainwater where possible.
Submersible Pump Design
The KRBS2 uses a submersible pump setup, meaning the pump is installed inside the rainwater tank rather than mounted beside the tank or on a wall.
This can be useful for properties where above-ground pump noise, pump exposure or available mounting space is a concern. A submersible system can help keep the installation cleaner and quieter when the tank and site conditions are suitable.
