Box 125 Performance



The traditional box shape has been specifically designed for heavy rainfall intensity, where fewer downpipes are desired. Offering a striking look to more traditional homes, it looks equally at home on a modern contemporary house.

All dimensions given are nominal.


Effective cross sectional area: 7500mm²(with 15mm free board)

Flow capacity: 112 litres/min

Minimum recommended fall: 1:500 = 2mm in 1m

Minimum downpipe:
Circular - 70mm
Rectangular - min. cross sectional area of 4125mm², smallest dimension at least 50mm.

Catchment area per downpipe based on the above flow capacity is given in Table 3.1G. Use Table 3.1B (Section 3.1.4 of Technical Manual) to determine the Rainfall Intensity to be used.
