The Rainmaster Favorit SC is a control and supply unit specifically developed for rainwater utilization.
It is designed for use in single-family and two-family residential buildings.
The BELGAQUA- and DVGW-certified construction, featuring a multi-stage centrifugal pump, integrated pump control, and automatic switchover to mains water in accordance with DIN 1989 and EN 1717, helps reduce space requirements and installation costs.
All inlet lines can be connected using quick-connect couplings. The system’s design ensures straightforward installation and reliable operation. The use of high-quality components guarantees dependable functionality and a long service life.

When the water level in the storage tank drops below a defined minimum, the system switches to mains water via a motorized multi-way ball valve. Unlike a solenoid valve, this setup ensures a secure mechanical separation of the rainwater suction line.
As a result, installation and operation below the backflow level and below the water level in the tank are permitted.
Since the backflow level must be considered in almost all regions, this feature is essential for the majority of residential installations.
