Platin AA Silentio Rainwater Harvesting System 1500-7500 Litres

Step into the future of sustainable living with the Platin AA Silentio Rainwater Harvesting System, a pinnacle of innovation from GRAF, the European market leader. This advanced system is designed to fulfil your non-potable water household needs, from toilets and washing machines to garden irrigation and outdoor cleaning.

How It Works:

• Rainwater Collection: Rainwater is efficiently captured from your roof, travelling through downpipes to the underground tank.
• Advanced Filtration: As the water enters the tank, it passes through an award-winning filter, ensuring debris-free storage.
• Efficient Water Management: The system includes a pump and control unit within your property that smartly draws water from the tank on demand.
• Mains Water Integration: When rainwater levels are low, the system seamlessly switches to mains water, stored in a cistern under the pump, ensuring uninterrupted water supply.
• Maximised Rainwater Usage: The unique design prevents mains water from topping up the underground tank, maximising rainwater harvesting.
• Digital Level Indicator: A digital indicator in the tank ensures precise monitoring and control of water levels.

Why Choose the Platin AA Silentio Rainwater Harvesting System?

• Eco-Friendly Materials: The underground tank is made of 100% recycled plastic, reflecting a commitment to environmental sustainability.
• Innovative Pump Design: Plus, enjoy peace of mind regarding water regulations with our external pump unit that incorporates a Family A Type A air gap.
• Installation Ease: The use of gravel for backfilling instead of concrete simplifies the installation process.
• Delivery Services: Enjoy the convenience of free UK mainland delivery.
