'First Flush'
Rainwater Diverter

A clever and simple addition to your rain tank installation, the First Flush Diverter kit helps to keep your tank water free of debris and foreign matter.

By installing the diverter between the roof and your tank, the first bit of water that comes through your pipe system is caught in the ‘diversion chamber’; once the ball floats to the top of the diversion chamber it obstructs the inlet and ensures that the rest of the rainwater flows past the diverter and on to the tank. The water in the diversion chamber drains very slowly until the chamber is empty again.

The volume of water collected by the diverter is determined by the length of pipe used to create the diversion chamber.
