How It Works: The Platin XL/XXL Direct systems works when rainwater is efficiently collected from your roof and travels through downpipes into a robust underground tank. As it enters, the water is filtered to remove debris, ensuring only clean, usable water is stored. This filtration process is critical for maintaining the integrity and longevity of the system by preventing sediment from accumulating in the tank. Automatic Mains Water Backup: One of the standout features of the Platin XL/XXL Direct is its mains water top-up unit. Located within the property for convenience, this unit automatically supplies water to the underground tank when rainwater levels are low, thanks to a float switch that monitors water levels. This ensures a continuous water supply, making it ideal for periods of low rainfall. Energy-Efficient Operation: The system includes a pressure-sensitive pump in the underground tank, designed to operate only when water is needed. The pump activates when a tap or valve is opened and shuts off when closed, allowing the system to repressurise. This pressure drop activation minimises electricity usage, as power is only used when necessary. Cost-Effective Installation: The Platin XL/XXL Direct offers a gravel backfill option instead of a traditional concrete backfill, saving approximately £60 per cubic metre on installation costs. This makes the installation process more affordable, faster, and less invasive. Flexible Installation Options: With the vehicle loading lid, this system can be installed under driveways or other high-load areas, maximising the use of space on properties where garden or yard space is limited. This feature allows homeowners to utilize their property fully without sacrificing valuable outdoor areas. Sustainable Materials: The tank is crafted from 100% recycled plastic, reflecting a solid commitment to environmental sustainability. This choice of material reduces the carbon footprint of producing new plastic and ensures the system is durable and long-lasting. Intelligent Water Management: Equipped with an automatic submersible pump featuring automatic restart and dry-run protection, the Platin XL/XXL Direct system offers hassle-free operation. These features safeguard the pump and system against damage due to running dry or power interruptions, ensuring reliable operation year-round. Opt for the Platin XL/XXL Direct rainwater harvesting system if you want a reliable, cost-effective, and environmentally friendly solution to manage your water needs. Its advanced features and efficient design make it ideal for modern, eco-conscious households.
