Downpipe straps can be supplied to easily attach the downpipe to the wall of the building. Shoes (135 degrees) and elbows (90 degrees) are available to help water flow to a specific area. Downpipe outlets are an added accessory to help channel water from the gutter to the downpipe.
Stratco's exclusive inlet filter design allows clean water to enter your tank while ensuring your downpipe remains free of unwanted debris. The unit incorporates a removable filter screen which enables quick and easy cleaning and maintenance.
Note: Component availability is State specific, please check prior to ordering.
As a general guide, in non cyclonic areas, for every 1m2 of roof area drained, 70mm2 of downpipe is required. This calculation is based on the assumption that the maximum rainfall does not exceed 125mm per hour.
It is considered the best practice to drain to different points, using smaller downpipes rather than to one large outlet. Where possible, downpipes should be spaced at not more than 12000mm centres.
For a more accurate guide, consult the Installation Code for Metal Roofing and Wall Cladding SAA HB39-1997.
