Mount the Rain Water Collection Filter to the rainwater pipe - and already, the water can be collected in a rainwater tank and used for irrigating the garden. The integrated fine-mesh filter collects leaves and dirt and can be easily cleaned using the fold-back cover. The rocker switch regulates the changeover from collect to non-collect of rainwater. To prevent tank overflow, the Rain Water Collection Filter is equipped with an overflow safety. The Rain Water Collection Filter can also be connected to installation pipes with 50 mm Ø. With DIN-suitable 90 mm throughput, the Rain Water Collection Filter is suitable for rainwater pipes with a diameter of 96 – 110 mm. The mating thread 33.3 mm (G 1) is suitable for the GARDENA Connecting Set (Art. No. 3815) for connection to a GARDENA Rain Water Tank.
