GRAF Carat S Household Rainwater harvesting packages feature their patented Optimax-Pro (self-cleaning) filter that requires minimum maintenance and provides over 95% water yield. The filter housing has a transparent lid for filter visibility and can be easily removed without tools.
The ECO-Plus System features an Aqua-Center Basic control unit that checks and regulates the entire water requirement. The floating switch-controlled monitoring of the tank ensures that the unit automatically switches to mains water supply if the rainwater level drops below the predefined minimum. As soon as the tank refills with rainwater, the Aqua-Center Basic switches back to rainwater supply, ensuring that only a minimum of mains water is used during longer dry periods.

Manufactured by injection compression moulding, these tanks boast unbeatable stability with each component produced to the highest accuracy. The tank dome can be rotated 360° and sits on a telescopic, inclinable shaft allowing it to be easily aligned to connection pipes and installed flush with the soil level.
