The system features a self-priming centrifugal pump that delivers rainwater sucked
from a storage tank (Fig. 4, rep. 17) to the points of consumption trough installation
pipes (Fig. 4, rep. 16).
The controller (Fig. 3, rep. 2) simultaneously ensures:
ƒ
The water continuity by switching the three-way valve (Fig. 3, rep. 6) to the mains
water network when the rainwater level in the rainwater storage tank is too low.
ƒ
The automatic start and stop of the pump.
ƒ
The pump's dry-running protection in case of water shortage.
The 11-liters break-tank (Fig. 3, rep. 3.) is designed according to the EN1717 standard
(AB type disconnection) and ensures a separation of the rainwater from the mains net-
work by means of an air gap.
The break-tank is filled by city main water through a float valve (Fig. 3-4, rep. 4). In
case of failure, the water overflow goes freely to the drain. The hose collecting the
overflow (Fig. 3-4, rep. 9) is not included.
