Graf Carat Direct Rainwater Harvesting System 2700-6500 Litres

The GRAF Carat Direct Rainwater Harvesting System is a complete rainwater harvesting system that feeds rainwater directly to your toilet, washing machine, or garden tap.

Available in sizes 2700L - 6500L

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.

• 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
