Rain Heads

For the plumber and informed building owner, this amazing hydraulic engineer certified, Australian designed, made and patented rainhead blows away all other rain heads on the market while making compliant installation a breeze. 

Dam Buster rain heads are available in varying sizes to suit box gutters from 200mm to 600mm wide. 


Free flow Sumps are absolutely unique simply because unlike all other sumps, they don't require the water level to rise in the box gutter before they operate in the overflow condition.  In fact they operate hydraulically in exactly the same way as the revolutionary Dam Buster rainhead.  

Far superior to any existing sump designs and with models suitable for all box gutters from 200mm to 600mm wide, Dam Buster sumps are part of the Australian design revolution in roof drainage. 

Side Outlets

Dam Buster side outlets use the power of gravity to safely change the direction of water flow in box gutters in a Deemed to Satisfy way.  No Performance Solution required here!

Side outlet devices are available in varying sizes to suit all box gutters 200mm to 600mm wide and can be easily installed, whether new or retrofit.
