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 going into the tank. With this system, there is a mains water top-up unit located within the property. This 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. 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 power off to the pump.
