Product catalog summary
Overview of Marley Rainwater Systems
The Marley Plumbing & Drainage rainwater range includes six gutter profiles and four downpipe options, featuring advanced Life4 technology for enhanced durability. The systems are suitable for various building applications, from small houses to large industrial projects.
System Specifications
The range includes Deepflow, Clip-master, Flowline, Deepflow150, Classic, and Industrial systems, each with specific dimensions and capacities. For instance, the Industrial system can handle up to 5.68 liters per second, while Deepflow150 can manage up to 6.0 liters per second.
Life4 Technology
Life4 technology enhances the lifespan of rainwater systems by using high-specification material for a capping layer, providing a high gloss finish and improved durability. Life4 products withstand up to four times the European weathering test duration, maintaining aesthetics and performance over time.
Key Components
Marley systems feature components like the easyclip for reliable jointing, notch adaptors for thermal expansion, and various pipe clips for secure installation. Gutter adaptors and drain adaptors are available for system compatibility and flexibility.
Roof Drainage Design
Design considerations include calculating effective roof area, understanding rainfall intensity, and selecting appropriate gutter systems based on flow capacity. The design ensures that gutters are fitted to handle peak flow conditions effectively.
Installation Guidelines
Installation involves using rafter arm brackets for structural support, especially in buildings without fascia boards. Notched gutters are recommended for ease of installation and thermal movement control.
Standards and Compliance
Marley systems comply with British and European standards, including BS EN ISO 9001:2008 and BS EN ISO 14001:2004, ensuring quality and environmental management.
Gutter Installation and Specifications
Positioning and Installation: According to BS EN 12056-3: 2000, eaves gutters should be positioned to intercept water flow at the roof edge, centrally under the roof tile. Gutters can be installed level or with a gradient of 1:600. Care must be taken to ensure the gutter does not fall below the roof tile, and the eaves course should not project more than 50mm over the fascia board for 112-125mm gutters.
Fascia Brackets: Marley PVCu gutter fascia brackets exceed Class H heavy duty requirements, supporting a load of 75kg. Brackets should be aligned using a string line, with centers not exceeding 1m. For cellular fascia boards less than 16mm thick, a timber support batten is recommended.
Hopper Heads: Flow capacities for hopper heads vary by size, with examples including RH252 (68mm, 5.14l/s) and SH60 (160mm, 19.63l/s).
Roof and Balcony Outlets: Marley offers a range of outlets, including 68mm PVCu and 50-150mm aluminum options.
Rise and Fall Brackets: RKF1 brackets can be used with clip-jointed gutters, with a recommended maximum center distance of 600mm.
Gutter Jointing: Clip-jointed systems require careful insertion to ensure performance. Notched systems allow for expansion and contraction without pulling apart.
Downpipes: Rainwater pipes are generally fitted externally, with joints not needing to be sealed. Pipe clips should be located at maximum 1.8m centers.
Standards and Accreditations: Marley products comply with various standards, including BS EN 12056-3: 2000 and BS EN 1462: 2004. Marley offers a range of systems, including PVCu soil systems, HDPE drainage, and acoustic soil and waste systems.
Product Specifications: Specifications for various gutter components, including sizes, codes, and colors, are provided, with adaptors available for different profiles.

Marley rainwater systems offer complete roof variety of building sizes product specifications, The iconic Marley socket The origins of the iconic double 'bump' on our rainwater pipe socket stem from the fact that Marley was the first rainwater gutter. The design emulated the traditional material most often used for drain pipes, cast iron. Deepflow, Clip-master, Flowline and Deepflow150 rainwater systems benefit from the Marley easyclip, which makes jointing both easy and reliable. The easyclip has twin compression tabs, which apply downward pressure onto the gutter seal, to ensure a watertight...

Installation data Gutter position Rafter arm brackets The spread of water as it leaves the roof edge can vary considerably depending on the rainfall intensity, type of roof surface and the pitch of the roof. BS EN 12056-3: 2000 recommends that eaves gutters should be tted in such a position that they intercept the ow at the roof edge and that gutters are tted centrally under the roof tile and close beneath it. Rafter arm brackets can be used with all Marley gutter systems. Additional structural xings should be provided when used with a clip-jointed gutter system, to enable key ttings to be anchored...

Gutter jointing Clip-jointed gutter systems Notched gutter systems Each joint is made by inserting the plain edge of gutter into the tting and locating under the rear clip. At the same time ease the front edge of tting forward and up until the gutter clips under the front edge. Care must be taken to ensure that each length of gutter is tted to the insertion mark on each tting. This is particularly important and attention to this will ensure trouble free performance for many years. It is possible to adapt the easyclip to make ttings suitable for ‘notch’ jointing, by tting a ‘notch adaptor’ into...

Downpipes General y Two different pipe clip xing methods are available. A one piece clip for ush xing or a two piece clip to t both the downpipe and pipe socket. These are used with backplate RCB300 and allow for adjustment. bl Where a RH25 hopper head is used, the RLE3 outlet adaptor with a pipe socket are required to provide the necessary transition from circular to square. Every rainwater pipe should have a clip located round the top socket to support the downpipe system. Intermediate clips should then be located at a maximum of 1.8m centres or in the middle of each length to maintain alignment....
