Promax Submersible Pump Water Rainbank Switch & Cabinet

RainBank is an automatic controller for rainwater harvesting. RainBank controls the water supply for toilet and laundry applications by automatically selecting the water source.  Rainwater is given priority with mains water as back up if the tank is empty or there is a power outage.

  • Simple to install with no adjustment necessary, saving time and money at installation                   
  • Feedback lights to indicate water source and faults                                                                                                   
  • No solenoid valves used                                                                                   
  • RainBank automatically switches between rainwater and mains water supply , so there is no need for consumer intervention.                            
  • Built-in backflow protection valve (dual check valve) in compliance with the requirements of AS/NZX 3500-1-2003 for added safety and assured protection of your mains water supply                                          
  • Incorporates pre and post filtration to ensure reliabillity and high water quality

We recommend you use a professional tank cleaning company to do this. A professional tank cleaning company is able to vacuum the base of your tank without emptying the water. Happy Tanks can clean your Tank if you are in the Auckland and Northland regions. We recommend a Google search to find a local cleaning company for your area. 

If you would like to clean the tank yourself, please see the links below for instructions on how best to do this.

Alternatively, you could consider installing a Tank Vac. These will remove build-up of sediment already present and help keep your tank clean all the time.
