The Maxima rainwater unit ensures a high supply capacity thanks to the large hybrid tank. In doing so, it combines all components required for operating the rainwater supply according to the two-pressure pump principle. The rainwater is pumped from the rainwater storage tank into the buffer tank of the hybrid system by the submersible loading pump. From there, the submersible pressure pump in the hybrid tanksupplies water to the consumption points. Mains water is added when necessary directly into the unit's hybrid tank, the buffer volume is 350 l for high demand peaks. Complies with DIN 1989 and DIN EN 1717.
