Marley downpipe systems are intuitively designed as a modular system, making repair and replacement much simpler. However, there is a technical element to installing Marley downpipes so if you are unsure, Marley recommends you seek advice from a trade professional.

Light Reflectance Values
Light reflectance value (LRV) is the total quantity of visible and useable light reflected by a surface in all directions and at all wavelengths when illuminated by a light source. The LRV scale expressed as a percentage ranges from 0, which is the darkest or least reflective, to 100, which is the lightest or most reflective. The LRV percentages of Marley’s rainwater products are:
Downpipe Clip Spacing – Vertical Installation
Place the first downpipe clip a maximum of 200mm from the bend using two stainless steel screws. Ensure the second and subsequent clips are spaced no more than 1.2 metres apart.
Downpipe Clip Spacing – Horizontal Installation
Place the first downpipe clip no more than 200mm from the bend or junction. Ensure the second and subsequent clips are no more than 1.0m apart. Note that horizontal downpipe should never be installed without a fall away from the spouting. Using a RB2.80 95˚ bend or correctly orientated RJ80 95˚ junction will help ensure a fall as these components have a shallow downward angle built into them.
