Siphonic Roof drainage vs. Gravity Roof drainageRoofs with a large surface can be drained on the basis of twodifferent principles, either by means of gravity drainage or by meanof siphonic drainage. Drainage by means of gravity typically utilizesonly 70% or less of the pipes capacity since the remainder isnecessary for ventilation.In contrast, siphonic drainage utilizes 100% of the pipe capacity.This requirement is met by using specially developed drains whichprevent the admission of air. Additionally, the siphonic system isoptimized by hydraulic calculations which systematically fill thepiping system up in cases of heavy precipitation. The total heightdifference between the roof drain and the backflow level can thenbe used for the pipe dimensioning.Siphonic drainageGravity drainage4” NOM4”NOM4”NOM4”NOM4”NOM3” NOM2” NOM4” NOM8” NOM6” NOM5” NOM4” NOMGravity drainageSiphonic drainageAdvantages of Siphonic drainage: A higher discharge rate as a result of a closed flow circuit allowing smaller pipe sizes. Space gained due to horizontal piping without slope below the roof deck. Lower material cost due to the use of smaller pipe sizes and shorter pipe lengths. Less labor cost due to fewer vertical pipes, less pipe penetrations through the foundation of the buildingand less excavation for underground piping. Cleanliness of the system due to higher flow velocities.

Siphonic roof drainage systems are designed to operate with full bore flow. The computations made for siphonic roof drainage systems therefore focus on single phase water flow. For the proper design of the maximum capacity of a siphonic system this is sufficient. However it is necessary to have a good insight in the start
A siphonic roof drain looks much like a traditional roof drain. The distinguishing feature of a siphonic roof drain is the air baffle. This air baffle is engineered and tested to prevent air from entering the piping system at peak flows. Other than the baffle, a siphonic roof drain has the same features as a traditional roof drain including a .
of the complexities of the design calculations, it is essential to use an established and proven analytical design program. Siphonic roof drainage technology offers huge benefits to the market, the end-user and the environment. The importance of siphonic drainage systems will only grow further in the coming years, triggered by market

Lindab Rainline Roof Drainage System Before you start It is the total area of the roof that decides the dimensions of the roof drainage sys-tem. The bigger the roof, the more water the system must take care of. It will pay in the long run to be careful when you measure your roof and calculate dimen-sions. Take your calculation to your local
