The Wavin Osma RoundLine rainwater adaptor is an essential component for homeowners and contractors looking to bridge the gap between 68mm circular downpipes and 110mm PVC-u drainage systems. It provides a reliable, weather-resistant connection for standard domestic rainwater management, effectively channeling runoff away from building foundations. While it is engineered for high durability and straightforward installation, users must ensure their existing gutter system is compatible with the RoundLine range to guarantee a watertight seal.

It acts as a connector to transition a 68mm circular rainwater downpipe into a 110mm underground drainage system.
It is specifically designed for the Wavin Osma RoundLine range; compatibility with other brands cannot be guaranteed.
When using a single downpipe, it can effectively manage a roof area of up to 163m².
No, this component is intended strictly for external rainwater management systems.
No, it is a push-fit component; however, basic cutting tools may be needed for the downpipe itself.
Ensure the pipe is inserted fully and verify that there is no debris preventing a flush fit.
Apply a small amount of silicone lubricant to the seal or the exterior of the adaptor to ease entry.
Check that the downpipe is properly supported by wall clips to prevent external force from shifting the adaptor.
To install, ensure the 110mm drain socket is clean and free of debris. Insert the adaptor into the socket, ensuring a firm fit. The 68mm downpipe should then be connected to the upper aperture of the adaptor. For care, periodically check the connection point during routine gutter maintenance. Ensure the adaptor remains unobstructed by leaves or sediment to maintain a free flow of water. If you notice any signs of movement or loose fitting due to thermal expansion, ensure that the downpipe clips are securely fastened to the wall to prevent the adaptor from being pulled out of alignment.
