New Davey Rainbank for Surface Pumps



Rainbank for Surface Pumps 

It is possible to reduce your mains water consumption by as much as 40% or more with a Rainbank when connected to a well plumbed rainwater tank. 

RainBank is an automatic controller for rainwater harvesting supplying water for toilet and laundry applications and can save up to 40% of a household's mains water use, helping to conserve water. A RainBank system automatically selects the water source with rainwater given priority over mains supply. Mains water is supplied when the tank is empty or in the event of a power outage.

Ideal for metropolitan rainwater harvesting on homes, garden irrigation and toilet blocks, RainBank uses patented, uncomplicated technology to providing a dependable solution to rainwater harvesting.


RainBank automatically switches between rainwater and mains water supply and can be mounted directly on to the pump or a nearby supportive wall for easy access. RainBank is an environmentally friendly solution, reducing flow to storm water systems; and has low power consumption in standby, yet provides seamless mains backup in the event of no rainwater or electrical interruptions.

  • KRB1NF - for use with pump model HP45-05, flow rate of 40 lpm at 200kPa
