Product description Garden Duo Filling machine. A specially developed rainwater drainage system that has two outputs. This not only makes it easy to connect 2 rain barrels, but the rain pipe can also be shared with the neighbor. Because more and more households have 1 rain pipe between 2 homes, it is not always possible for everyone to collect rainwater. This problem has been solved with the duo filling machine. This filling machine also has a special winter closure to protect the rain barrel against weather influences during the winter. By means of a sliding system, the water openings in the filling machine can be easily closed during the frost period. The duo filling machine is supplied with a complete connection set consisting of 2 flexible hoses and 2 rubber sealing rings.
