8500 Litre GRAF CARAT Garden Comfort Underground Rainwater Harvesting System (Garden Irrigation)

The Graf Carat Garden Comfort system is designed for irrigation and outside cleaning purposes. Rainwater is collected from the roof of the property and is fed into the 8500 litre underground tank via the downpipes. The Graf Carat 8500 Litre Package comes as standard with a PE Telescopic dome shaft so that it can be adjusted to meet the ground level, there is the option to have this in Composite Lid if the tank needs to have vehicles driving over it. On entry to the underground tank, the water passes through a filter, to prevent any debris going into the tank. 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.
