What happens when my tank is empty?

The rainwater consumers in your home are supplied by a separate supply network. This video presents the GRAF Aqua-Center-Silentio, which automatically controls the rainwater system and continually monitors the rainwater reserve in the tank. If the tank is empty, it supplies drinking water to the supply network as required. Your home is therefore assured a reliable supply of water at all times thanks to the convenient GRAF Aqua-Center-Silentio system control.
