The Graf Direct-supply system is designed to support WC’s, washing machines, irrigation and outside cleaning purposes. Rainwater is collected from the roof of the property and is fed into the underground tank via the downpipes. On entry to the tank, the water passes through a filter, to prevent any debris from going into the tank. With this system, there is a mains water top-up unit located within the property.
The unit supplies mains water to the underground tank when the rainwater level is low. The operation on this unit is controlled via a float switch and there is a pressure-sensitive pump located in the underground tank. When a valve or tap is opened, water will be pumped under pressure until the valve is closed, allowing for the system to repressurise turning the power off to the pump.
