Assembly, installation, and maintenance-friendly

Assembly of the RAINMASTER Eco is not complicated. It is delivered complete with flexible hoses for drinking water and pressure line, expansion vessel, stopcock as well as a pressure gauge.

Wall mounting

The RAINMASTER Eco is designed for wall mounting. 

Mains water connection

Connection to the mains water line is completed with the flexible hose provided and overflow screw joint.

Pressure line connection

The pressure connection set, including expansion tank, stopcock and ventilation cock, is connected to the unit with a flexible hose.

Suction line connection

The connection to the rainwater cistern is made with the suction line.

Emergency overflow

The unit is connected to the house discharge pipe with a HT pipe DN50.



The floating switch is installed in the cistern (above the RM Eco intake) and is connected to the RAINMASTER Eco controller.


The dry-running diaphragm pump doesn't require priming of the pump. This makes commissioning very easy:

  •  Plug the unit into the power socket
  •  Ventilate the system with the ventilation cock
  •  Close the ventilation cock when the water coming through shows no  more sign of bubbles 
  •  Open the pressure stopcock and ventilate the pressure line to the  consumers
  •  Put the unit cover back on

Finished! Now the system is ready to save water.
