Carat Garden Comfort XL/XXL Rainwater Harvesting System 8500-26000 Litres

Effortless Installation and Operation: The Carat XL/XXL Garden Comfort is engineered for simplicity, making installation and usage straightforward for homeowners. With clear instructions and user-friendly components, you can get your system up and running quickly without needing professional assistance.

Automatic Water Activation: Equipped with a pressure-sensitive pump and a simple hose connection socket, this rainwater harvesting tank ensures water is easily accessible when needed. The system automatically activates water flow upon sensing a pressure drop when a tap or hose is turned on, providing hassle-free irrigation for your garden.

Subtle Design: The flush-to-ground lid preserves the aesthetics of your landscape and provides unhindered access to the tank for maintenance or inspection. This discreet design means you can enjoy the benefits of rainwater harvesting without compromising your garden’s appearance.

Energy-Efficient: To reduce electricity use, the Carat XL/XXL Garden Comfort uses a pressure drop activation system that only consumes power when necessary. This intelligent feature lowers energy bills and the environmental impact of maintaining your garden.

Advanced Filtration Technology: The system incorporates integrated filter technology to ensure 100% water yield, meaning every drop collected can be used. This efficiency makes this system economically viable and environmentally friendly.

Choose the Carat XL/XXL Garden Comfort for a sustainable, easy-to-use, and discreet rainwater harvesting solution that keeps your garden lush while reducing utility costs and water wastage. It is perfect for environmentally conscious gardeners looking to reduce their ecological footprint and make better use of rainwater in the garden instead of using mains water.
