Abstract (en)
[origin: WO2004018795A1] The present invention relates to a siphonic apparatus (1), for draining liquid, particularly for draining rainwater, off a roof (2), comprising a plurality of tubular members (4, 6). Each tubular member (4,6) has an inlet opening (8,10) arranged to be disposed at a different height relative to another opening. As the precipitation increases the tubular members with inlet openings located at the lowest level will reach their maximum capacity beyond which point liquid can be drained through the tubular members which have inlet openings positioned at sequentially increased distances above the inlet of the tubular members which are working at their maximum capacity.
