Building verschiedene Various systems are available to collect the valuable rainwater that runs off the roof. Rainpipe flaps prevent rainwater from overflowing in the drums.

Roof drainage automatically or manually diverts the precious water into a suitable storage container. In addition to the matching gutter and a downpipe, the installation of a rain tube flap makes sense. This ensures that the water runs into a collecting container.

The installation and the material

If a rain-tube flap is retrofitted, only one piece is cut out of the downpipe and the flap is inserted there. Size of the flap should be adapted to the accumulating water and the gutter.

Rainpipe flaps are usually made of metal, this material is much more robust and durable than plastic. Copper is the noblest material, zinc is cheaper.

Adjustment to the water level

Rainpipe flaps are usually maintenance-free and can simply be folded up in the winter months. They are equipped in different materials, designs and details. High-quality rain tube flaps can be adjusted to a desired water level.
