Commercial Insitu

Lower your environmental footprint

This metal rain head can be easily painted to suit any building’s colour scheme and incorporates 0.955mm stainless steel mosquito proof mesh.

Rain Heads filter leaves and debris out of your downpipes with their 0.955 micron screens. They also minimise splashing to increase the volume of rainwater you harvest.

Rain Heads secure the system with the 0.955 micron mosquito-proof screens that prevent insects and other animals from entering and breeding or living in your downpipes.

Product Installation


Gutter, Eave & “Mid” Mount
  1. Locate the position at which you will be installing your Leaf Eater Commercial rain head. Whether this is directly under your eave or midway down your downpipe, it should be a minimum of 500mm above your tank inlet and tank overflow pipe.
  2. Cut and bracket your bottom downpipe to the wall, being sure to offset it 30mm from the wall.
  3. Insert your Leaf Eater Commercial rain head into the pipe and mark the side flange fastening holes. Remove your rain head and prepare the necessary fastening points. Then reinsert your rain head and fasten it to the wall, ensuring it’s adequately supported by the wall structure.
  4. Cut your upper downpipe at an angle of 30 degrees to match the angle of your rain head’s stainless steel screen. Cut the pipe 50mm above the rain head screen and install it with a 30mm offset from the wall.


Your rain head’s Clean Shield™ screen is mostly self-cleaning. However, it is prudent to periodically inspect it to check if cleaning is necessary.


How high should I install my Leaf Eater rain head?

Rain heads must be installed so they are higher than the inlet on your rainwater tank. This is necessary to allow water to flow through the pipework to your tank and to avoid water overflowing from your rain head.

If you have a wet rain harvesting system (a system where pipes feeding your tank sit below the level of the tank inlet and hold water), you should install your rain head a minimum of 500mm (19.6″) above the height of your tank inlet. Where possible, we recommend that you maximise the height of your rain head in relation to your tank inlet even further. This may be especially necessary if you have a longer wet system.

For best results, consult a licensed plumber to discuss the optimal height of your rain heads so you can avoid damage to your property, risks to your personal safety and other negative consequences of water overflowing from your rain heads.

Should I mount my Leaf Eater rain head at the gutter or on the wall?

The ideal location for a rain head is directly beneath your gutter outlet at the fascia board or eaves. Where access is difficult – for example, on a two-storey house – your rain head can be installed “mid” mount on the wall lower down away from the gutter. When selecting your installation point, it’s important to consider the height of your rainwater tank inlet, as your rain head should be installed a minimum of 500mm (19.6″) above the height of your tank inlet. Your chosen installation point should tread the balance between maximum height in relation to the height of your tank inlet, and safe and easy accessibility for maintenance.

I have pine needles. Which Leaf Eater rain head should I use?

All our Leaf Eater rain heads are suitable for use in areas with pine needles. However, due to the fine size of the needles, more regular maintenance will be required to remove any pine needle debris from your rain head.

My Leaf Eater rain head is overflowing. Why is this happening?

The most common reason a rain head overflows is insufficient or irregular maintenance. Check and clean your rain head screens regularly to ensure they continue to function optimally.

Alternatively, your rain head may overflow if there is insufficient “fall” from the rain head to the tank inlet – in other words, if your rain head is not positioned high enough in relation to the height of your rainwater tank inlet. A height difference between your rain head and tank inlet is necessary to allow water to be pushed through your rain harvesting system under gravity.

Will my Leaf Eater rain head splash water into my covered patio area?

Rain heads with an open “face” have an angled, self-cleaning screen designed to minimise splashing as leaves and debris are deflected away from the flow of water. This applies to all our rain heads that feature our Clean Shield screens, as well as the Leaf Eater Original.

If you are still concerned about splashing, consider choosing a rain head with an anti-splash cover such as the Leaf Eater Slimline or Leaf Eater Ultra.

What’s the difference between each rain head in the Leaf Eater range?

All our Leaf Eater rain heads feature mosquito-proof screens and are designed to keep leaves, debris, mosquitoes and other pests out of your downpipes and rain harvesting system. Several of our rain heads feature patented VH pivots for installation on horizontal and vertical downpipes, some feature anti-splash covers and some feature additional technology such as our Hydro Activated Filtration screen system and red overflow indicator flags.
