The First Flush Post/Wall Stand Water Diverter is a versatile unit that can be mounted on a wall, post or stand, to hold larger volumes of water. It can be adapted to suit a wide range of applications and will manage single or multiple pipes coming from the roof to divert between 20 and 150L.

See our story about our recent Aid project on Tokelau that included this product.

A simple practical approach- Diverting as little as 25 litres of water will significantly improve water quality divert as much water as the system can afford to maximize water quality.

The kit is easy to freight, and the diverter volume can be made on site to match exact requirements – just add the appropriate length of 300mm pipe which can be purchased from your local plumbing merchant.

The kit includes a saddle and a galvanised steel wall-mounting bracket. A galvanised steel stand is an optional alternative to post or wall mounting.

How much water to divert

It is important to prevent heavy sediments and other roof pollutants from entering the rainwater tank. The amount of water diverted should be a minimum of 20 litres per 100 square metres of roof area (or 0.2L per m2). In calculating the amount of water to divert, consideration can be given to (1) the surface area of the roof, and (2) the amount of pollutants on the roof and gutters.

Multi pipe feed systems

These water diverters can handle more than one pipe

Single or multiple pipes coming from the roof can be connected into a "T" and coupled together so that the first flush from the roof enters the diverter chamber. The pipes are connected from the "T" into the tank.
