When it rains, water slowly builds up in the roof guttering system before it exits through the downpipe. The first flush of water from the roof can contain amounts of bacteria from decomposed insects, skinks, bird and animal droppings and concentrated tannic acid. It may also contain sediments, water borne heavy metals and chemical residues, all of which are undesirable elements to have in a water storage system.
 
 

The ultimate high performance rain head 
 
The Leaf Eater® is the ultimate high performance rain head for use in heavy rainfall areas. Not only does it protect the home by preventing gutters from blocking and flooding of eaves, the Leaf Eater® also improves water quality and reduces tank maintenance.

Leaves and debris that build up in gutters can be flammable and represent a significant fire risk. By screening leaves onto the ground, the Leaf Eater® prevents gutters from blocking and eliminates a fire hazard.

A secondary stainless steel screen is included to keep mosquitoes and vermin out of downpipes in a “wet” system. With the removal of the secondary screen, the Leaf Eater® is ideal for use purely as a debris removing device even when rainwater is not being collected.

How it works
As water flows from the gutters it carries leaves and small pieces of debris. The Leaf Eater® incorporates a flow directional gutter outlet which directs the flow of water onto the face of the primary screen. The water washes over this screen which has a 6mm aperture and is set at an angle to the horizontal of around 45°. This angled screen is self-cleaning and forces the leaves and debris away allowing the water to continue through towards the secondary screen.  
 
The secondary stainless steel screen of 0.995mm aperture further filters the water and prevents mosquitoes and vermin from entering the pipe system to the water tank. Once the water passes through this insect proof screen it flows into the downpipes.

The Superhead First- Flush Diverter is installed anywhere before the inlet of the water tank and will automatically divert the first polluted water from the roof when it rains. After the flush is performed it automatically diverts the clean water into your rainwater tank.

The Superhead combines 4 products into 1 device to provide maximum effectiveness and value for money. Here are the 4 parts

1. Rain Head
A rain- head is an important part of rainwater collection. It provides a break in the dowpipes so that any leaves that enter the downpipes can be cleared quickly. If blockages occur then your downpipes and gutters will overflow which can often cause major damage to your property.

2. Leaf Screen
The first stage filter is the large leaf screen. Leaves and other debris are prevented from entering the tank by a 8mm screen. The specially designed mesh allows the leaves to fall off while minimising splashing.

3. Adjustable First- Flush Diverter System
The first rain is diverted to a standard 90mm downpipe (not included) so that dirt and other pollutants from the roof don't enter the water tank. Once the First Flush System has filled the internal flap will close and divert clean water through the rear outlet and into the tank.

A drain on the bottom of the First Flush System can be adjusted to alter the rate the system drains. During periods of frequent rain it is not necessary to completely flush the whole system each time. By changing the drainage rate you can maximise the amount of water collected.

*The flush volume depends on the length of downpipe used. Storage volume of 90mm pipe is 6.4 Litres per metre

The Drainage Plug is also compatible with standard poly retic fittings so the flush water can be directed to the garden or other location. The drainage plug is simply replaced with a screw fitting and a standard valve, or drip fitting

4. Insect Screen
The final filtration is done with 1mm stainless steel mesh that will stop any insects or floating debris that may enter the tank.
