Graf Grey Filling Device
Make rainwater harvesting effortless with the Garantia Grey Filling Device. This clever attachment connects to round drainpipes measuring 70mm, 80mm, or 100mm, automatically diverting rainfall into your water butt or tank.
The built-in filtration system keeps your collected water clean by catching leaves and debris before they enter your storage. Intelligent overflow protection prevents tank flooding, while the adjustable Summer/Winter mode safeguards against frost damage during winter months.
Perfect for gardeners committed to water conservation, this device maximises every rainfall and cuts your water consumption. Assembly required.
Care Instructions
During the Winter months the diverter should be turned to 'Winter Function' to prevent water entering water butt/tank - this is to reduce the chance of freezing and cracking. Filter should be removed and cleaned as required.
