A water butt with a downpipe connection is a simple and inexpensive way to collect rainwater and use it sustainably. The principle behind it is straightforward: rainwater that runs off the roof of a house is diverted through the downpipe into the water butt. A rain collector or downpipe filter is required to divert the water into the water butt and is installed in the downpipe. When it rains, the collector directs the water into the barrel. A downpipe filter ensures optimum water quality. Thanks to an overflow stop, excess water simply flows back into the rain pipe. In winter, the inflow to the rainwater tank is stopped.

A rain collector therefore fulfills several tasks at once:

• Filtering: Leaves, dirt, and insects are retained so that the water in the barrel remains as clean as possible.
• Overflow protection: As soon as the barrel is full, the collector automatically diverts the water back into the downspout.

Installation is simple: a piece of the downpipe is sawn out, the rain collector is inserted and a hose is led from there to the water butt. Thanks to the simple switch from summer to winter mode, no rainwater flows into the connected barrel during the switchover in winter. This prevents the water butt from freezing.

The water can then be conveniently removed from the water butt using a tap. This is screwed into the standard threaded connection on the container without the need for drilling.

A water butt with a downpipe connection is a cost-effective, environmentally friendly solution for saving water. This can significantly reduce drinking water consumption in the garden, especially in the summer months.
