Rainwater standpipe accessories from GRÖMO – Connect what belongs together.

Find a connection.

The connector pieces from GRÖMO ensure that the connection from the standpipe to plastic pipes and acoustic transmission line cast iron pipes is perfect. With these pipe accessories, you have countless options for pipe connections and full freedom of choice. Just insert the sealing element, connect, and the backflow-proof, gas-tight transition from standpipe to main system is ready.

We naturally produce our connectors from high-quality galvanized steel, weather-proof and corrosion-resistant. The inside of the connecting piece is coated and thus provides protection from deposits and accumulation of dirt. So the flow is guaranteed for the long run.
