Reducing water consumption and provides a natural source for gardening
Lower water bills with grey water and rainwater
RP80 is made from Polyvinylchloride (PVC) and are designed for durability and efficiency in drainage, waste, ventilation, electrical/communication conduit, stormwater, water supply, and irrigation systems. The products are manufactured by Marley New Zealand and are part of a comprehensive range that includes non-pressure and pressure pipes, as well as gutter and downpipe systems.
RP80® 80mm round downpipe has been the most popular downpipe system in New Zealand for over 30 years.
- Streamlined design for greater style
- Compact 43˚ bends available for greater versatility. E.g. tight soffits or stormwater installs
- Adjustable clips with spacers to suit any cladding variation
Available in range of colors

INSTALLATION
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:
| COLOUR | LRV % |
| Black | 4 |
| Copper | 15 |
| Grey Friars® | 11 |
| Ironsand® | 8 |
| FlaxBlack® | 7 |
| Titanium | 42 |
| White | 90 |
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.
