Rain water unit for feeding user points - incorporates pressureless feed arrangement, with overflow and lowest fill level indicator

摘要

From the unit rainwater can be fed by means of a pressure increasing component to users, and a connection is provided to the drinking water mains for feed to users when the rainwater availability is insufficient. An additional pressureless water feeder (14) is incorporated, which is fitted with its own overflow (18), to which, dependent upon its state of fill, can be fed with drinking water. It can also be connect ed via the pressure increasing component (11) to users. In the connections between the rain water feed unit (1) and the pressure increasing component (11), and also between the additional water feeder (14) and the pressure increasing component (11) is a magnet valve (6, 7) controlled by the lowest full indicator (5). USE - To feed rainwater collected from roofs of buildings to users.
