Effective Cross Sectional Area: 5100mm2
Flow Capacity: 70 litres/minute
Material: uPVC (Unplasticised PVC)
Minimum Recommended Fall: 1:2000
Bracket System: Internal brackets. To be spaced at max 500mm centres (reduce to 300mm in high wind or snow prone areas). All Marley Spouting bracket systems create + maintain a 10mm gap between the fascia and the back face of the spouting to allow water to spill to the exterior of the building envelope (as recommended in BRANZ Technical Bulletin Issue 509, “Sizing Gutters and Downpipes”, Clause 4.01).
Spouting Capacity:
| Rainfall Intensity* (mm/hr) |
40 | 50 | 60 | 70 | 80 | 90 | 100 | 110 | 120 | 130 | 140 | 150 |
| Maximum Catchment Area per downpipe(m²) |
104 | 84 | 70 | 60 | 52 | 46 | 42 | 38 | 35 | 32 | 30 | 28 |
* As per NZBC E1 – Surface Water, Rainfall Intensity equates to a 1 in 10 year storm and varies depending on geographic location. For example, 100mm/hr is a general rule of thumb for the Auckland region however please refer to hirds.niwa.co.nz for current rainfall intensity specific to your location.

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

STORAGE AND HANDLING
If storing Marley uPVC spouting and downpipe systems for a long period of time, the product should be kept in its original polyethylene sleeving and the fittings kept in their cartons. Both should be stored inside a building, out of direct sunlight.
Furthermore:
- Profiles should be well supported and stored on a flat surface to avoid deformation. Avoid stacking too many bundle packs to prevent overloading. A maximum of 4 packs high is recommended.
- Fittings supplied in cartons should be stored under cover in a cool dry place and remain packed until required for installation.
Solvent welding MCS must be securely stored in a cool place, out of direct sunlight and away from any heat source. If the only option is to store the spouting and downpipe for long periods in strong sunlight, they should also be covered with a light coloured opaque sheet.
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 |
