With 170 litres of storage volume, the rainwater barrel supports targeted rainwater collection for garden irrigation and other applications around the house. The container is designed for installation on the wall of the house and is therefore suitable for small locations where a water container for the garden otherwise takes up too much space. The downpipe connection is designed for a maximum recommended roof area of 50 m². This makes the rain barrel for the garden a practical water reservoir for free use of rainwater.
This water butt is built as a wall tank for tight spaces and uses only a small base area of 42 x 40 cm. The narrow water butt fits on the wall of the house and is therefore also suitable for the balcony. As a square water butt, the container looks quiet and tidy instead of bulky. The graphite grey look makes the rainwater wall tank a modern solution for outdoor use. So the rainwater tank combines a slim shape with a clear appearance. Especially in small locations, this leaves more usable area free.
The ready-to-connect complete set facilitates installation directly on the downpipe and turns the water butt with downpipe connection set into an immediately usable solution. The included downpipe connection filters dirt from the rainwater, automatically fills the wall tank and prevents the full container from overflowing. For installation, only 16 mm distance between downpipe and house wall is sufficient. The connection is suitable for DN 70-100 and therefore for standard downpipe systems. In addition, the operation can be easily changed from summer to winter.
The rainwater container is made of recycled plastic and thus follows a sustainable product design for everyday use in the garden. At the same time, the container is 100% recyclable, combining use and recycling in a thoughtful concept. Weather-resistant materials with high UV protection support a long service life outdoors. As a plastic water butt, the wall tank remains robust and easy to clean. The production made in Germany also stands for clean workmanship.
For water removal, this water butt with tap offers a total of five threaded connections with 19 mm on the front and sides. A plastic outlet tap in brass look is included, so that the water butt with outlet tap can be used directly. In addition, the connection is also suitable for a hose set as an optional accessory. On the top sits a lid opening with 18 cm diameter. The container can be completely emptied via the bottom connection. Emptying the water butt is required before the frost period.
