ABSTRACT:
A rain water roof outlet for a building for conducting rain water from a roof as an airless flow, i.e. as a full water flow. The arrangement includes a vertical pipe which at its upper end is connected to a wider trough mounted at the level of the roof. In the trough, above the mouth of the vertical pipe, is mounted a lid, which by special formation of its shape or by means of additional elements is adapted to increase the friction against the water flowing towards the mouth of the vertical pipe. This friction counteracts the tendency of creating whirls in the water stream and thereby contributes to producing full water flow in the vertical pipe by preventing air entry. The lid is preferably a net.
