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...

The effective roof area to be drained. 3. The flow characteristics of the gutter system. 4. The number and position of downpipes. 1. Effective roof area The effective roof area can be determined by calculation in accordance with the following: Approved Document H, Part H3. The formula and example shown below reflects the method used in the above standard to calculate effective roof...

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...

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’...

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...
