The Dam Buster Rainhead
This amazing Deemed to Satisfy (DtS) by Expert Judgement, hydraulic engineer certified, Australian designed and made rainhead, is quite simply the best rain head available anywhere in the world today.
The Dam Buster rainhead is simple to install while also being a great looking, top quality product that actually works straight out of the box and can be used absolutely anywhere in Australia.
Simply determine the 1:100 year ARI flow rate for the roof being serviced, then select the correctly sized rainhead and downpipe combination from a design table.
Fitting non-conforming and untested roof drainage products creates an unacceptable risk of internal building flooding during even modest storm conditions. If in doubt, ask your current rain head supplier for a copy of the hydraulic engineers conformance documentation for their product.
For Architects and Designers, Dam Buster rain heads will substantially minimise the visual impact of box gutters on the form of a building by making the rain head size as small as possible while still ensuring 100% reliability when it matters. The extremely high performance of all Dam Buster rainheads in the overflow condition provides additional safety not offered by other commercially available rainheads.

Now recognized across the country and protected by various Australian and International Patents, Dam Buster rain heads won an Australian Good Design Award in 2018 and were also featured on Australia By Design Innovations Series 2, 10 Network Australia, 2018.
Models are available to suit all box gutters from 200mm up to 600mm wide. The unique retrofit panel (supplied) also adjusts to odd box gutter sizes and configurations if required.
Every Dam Buster has independent hydraulic engineer certified overflow capacity of at least 16 litres per second.
Naturally Dam Buster rain heads must be correctly sized according to the roof area using the 1:100 year ARI for the location of installation, and also used in conjunction with correctly sized downpipes.
Because each Dam Buster rain head is a piece of engineering excellence and certified model by model, unfortunately we do not make custom sizes.
Standard Range: Zincalume is the standard material in all sizes between 200mm and 600mm. Colorbond colours are at this stage only available in 200mm and 300mm sizes: those colours are Monument, Woodland Grey, Surfmist, Dune and Night Sky. All Dam Buster products can however be easily powder coated at extra charge to any colour in the Dulux range including all Colorbond colours.
Custom Order: Stainless steel 304, stainless steel 316 marine, Corten steel, copper etc. Almost any flat metal can be used to suit your personal project requirements - ask us for a quote
Contemporary, Traditional or Round Fronted designs are available to suit your individual requirements.
Our optional top trim piece also provides a more traditional appearance and is simply fixed over the top of the contemporary rain head by the installing plumber (not available for curved front models).
For maximum flexibility, Dam Buster rain heads can also be simply converted on site to suit eves gutter installations.
DAM BUSTER rainheads are Deemed to Satisfy by Expert Judgement to meet or exceed the performance and overflow requirements of AS/NZS 3500.3, SA-HB39 and SA-HB114.
This absolutely unique product protects buildings from flooding internally due to over topping or back flooding of box gutters in severe storm conditions and the ingenious design also ensures a leak free seal between the box gutter and the rain head. All Dam Buster rain heads enable extremely high but entirely safe flow rates during normal operation, making them the obvious choice to protect any building.
For the plumber, Dam Busters are very high performance, conforming roof plumbing products which can be installed with absolute confidence.
Fully and independently engineer tested to the limit of Australian Standards and far beyond, Dam Busters are a totally unique Australian invention and the biggest worldwide step forward in rain head design for well over 100 years.
Give them a go - you won't look back.
