MARLEY Plumbing & Drainage Solutions Roof drainage design Design basis To assess the suitability of a gutter system to drain the roof of a building the following factors need to be taken into consideration: 1. The effective roof area to be drained. 2. Rainfall intensity. 3. The flow characteristics of the gutter system. 4. The number and position of downpipes. Roof pitch 1. Effective roof area The effective roof area can be determined by calculation in accordance with the following: • BS EN 12056-3: Roof drainage layout and calculations. • The Building Regulations 2002 Approved Document H,...

Installation data Gutter position 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: recommends that eaves gutters should be fitted in such a position that they intercept the flow at the roof edge and that gutters are fitted centrally under the roof tile and close beneath it. Rafter arm brackets can be used with all Marley gutter systems. Additional structural fixings should be provided when used with a clip-jointed gutter system, to enable key fittings to be anchored and...

Gutter jointing Clip-jointed gutter systems Notched gutter systems Each joint is made by inserting the plain edge of gutter into the fitting and locating under the rear clip. At the same time ease the front edge of fitting forward and up until the gutter clips under the front edge. Care must be taken to ensure that each length of gutter is fitted to the insertion mark on each fitting. 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 fittings suitable for ‘notch’ jointing, by fitting a...

Downpipes General Two different pipe clip fixing methods are available. A one piece clip for flush fixing or a two piece clip to fit both the downpipe and pipe socket. These are used with backplate RCB300 and allow for adjustment. 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 2m centres or in the middle of each length to maintain...
