The Graf Filling Device attaches to round drainpipes (70mm, 80mm, or 100mm) to efficiently harvest rainwater for garden use. Its integrated filtration system removes leaves and debris before water enters your water butt or tank. The intelligent overflow prevention system protects against water butt flooding, while the adjustable Summer/Winter setting prevents cold-weather cracking when switched to Winter mode. Assembly required. Care InstructionsDuring 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.
