RainCatcher Filter Diverter


Weight:                               3kg

Material(Black):                  Fully recycled plastic

Colours available:              Black and white as standard from stock

Any colour for own branding. MOQ 50 units

The RainCatcher filter diverter is a simple but effective filter diverter that is suitable for all downspouts both square and round and all materials up to a diameter up to 110mm. Rainwater is filtered by the internal and removable basket, it diverts to the above ground tank via a supplied hose tail connection and supply pipe, when the tank is full; the rainwater is automatically re-diverted back to the filter and then down the downspout. The unit can also be used with underground tanks and with infiltration trenches as a simple silt trap.

Any diverter, any size anytime!

In-tank Filter

Our straight in-line filter (also available with an offset option or as a pre-tank filter within a chamber)


The filter sits in the neck of the tank, rainwater is delivered through the left side and travels through the filter internal basket down the bottom of the filter to the (not supplied) 110 pipe which is attached to the calming inlet ‘foot’ which prevents the incoming rainwater disturbing any sediment in the tank. Debris runs along the filter basket and is removed via the supplied overflow siphon. As the tank fills, the water rises op the pipe and flows out of the overfow siphon, also removing any remaining debris from the filter basket.

Basket Filter


Rainwater is delivered in to the tank via a standard 110mm underground pipe. It falls to the bottom of the tank. This filter system is really only suitable for garden irrigation systems. An overflow siphon is attached to the outlet pipe.



Groundwater Module


Allows placement of tanks in areas with high water tables

Two groundwater valves with biological and mechanical filters, includes drill bit with centre drill for installation. Stops tanks from rising in areas of high water table

Calming Inlet



Sits at the bottom of the tank and ‘calms’ the incoming rainwater, stopping the disturbance of any sediment in the bottom of the tank

Floating Extraction Kit

Connects to the pump and floats on the top of the water level, allowing extraction of only the cleanest rain water

Rainwater Labeling Set

Black and Green Rainwater Pipe
