Graf Carat Direct Rainwater Harvesting System 2700-6500 Litres
from £1,923.57
The GRAF Carat Direct is a complete rainwater harvesting system that supplies rainwater directly for household or garden use, including toilets, washing machines, and outdoor taps.
Available in sizes from 2,700 L to 6,500 L, the system provides flexible storage for a range of property sizes.
Rainwater is collected from the roof of the property and 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.
This unit supplies mains water to the underground tank when the rainwater level is low. The operation of 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 the system to repressurise turning the power off to the pump.
Key Features
Direct-feed system using a pressure pump
Supplies rainwater to indoor and outdoor outlets
Pre-assembled for quicker, easier install
Economical Gravel Backfill
Eco-Friendly Construction: The underground tank is made entirely from 100% recycled plastic, emphasising our dedication to sustainability.
Effortless Operation: The automatic submersible pump comes with automatic restart and dry-run protection, ensuring a seamless and low-maintenance operation.
Continuous Water Supply: Unique to this system is its integrated mains water back-up. When rainwater levels are low, the system automatically tops up the underground tank with mains water, ensuring you always have a water supply.
Vehicle Loading Lid (optional): Ideal for properties with limited space, this feature allows for installation directly in driveways without sacrificing functional garden space or property aesthetics
