Promax Rainwater Collection Kit

Bundle and Save! Cleaner Water to Your Tank 

Our Accessory Bundles are an easier, and cheaper way of purchasing the accessories you need to help you get the very best out of your water tank. This kit consists of two Promax products designed to deliver cleaner rainwater to your tank: the Leaf Eater Rain Head and the 90mm First Flush Diverter Kit.  

The Leaf Eater fits into your downpipe system and is the first line of defence in stopping larger debris like leaves and branches from getting into your tank. The primary 6 mm mesh screen keeps the bigger stuff out, and it’s backed up with an insect-proof 0.995mm secondary screen to deal with the tiny critters.  

The First Flush Diverter Kit can be thought of as the second line of defence in keeping unwanted matter out of your tank.   It enhances rainwater quality by diverting the most contaminated water that washes off your roof with the first few millimetres of rainfall. The kit includes a T junction, ball and drip-drainer, with the first flush diverter easily installed on walls, posts, stands or even under your eaves. Simply add a customised length of pipe (not included) to divert your desired volume of dirty and contaminated water away from each downpipe.  


This kits includes:

  • Leaf Eater Rain Head
  • 90mm First Flush Diverter Kit

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.
