Most areas of New Zealand experience between 600–1600mm of rainfall – The highest recorded was 18,000 millimeters at Cropp River, Hokitika. With this in mind you need a strong performing spouting and downpipe system. Marley Typhoon spouting has been designed for the efficient flow of rain water and when used in conjunction with Marley’s 80 mm round downpipe system can withstand prolonged heavy rainfall.
We know this is fact through extensive field testing through the design process testing it with fire hoses over several weeks.
