Description
The Wavin Osma 110mm Rainwater Adaptor (68mm Round Pipe) is a polypropylene drainage fitting designed to connect a 68mm round PVC-U downpipe into a 110mm underground drainage system. Ideal for external use, this adaptor provides a reliable transition between above-ground rainwater pipework and below-ground foul or surface water pipe runs.
This fitting is typically used to terminate vertical rainwater downpipes at the ground level and direct rainwater into the underground network. It is suitable for connection to either a 110mm OsmaDrain socket or plain-ended spigot. The adaptor ensures a secure, watertight fit and maintains alignment with minimal disruption to the flow of water.
Manufactured from robust and lightweight polypropylene, this rainwater adaptor is corrosion-resistant and easy to install without specialist tools. Its simple push-fit design makes it a quick and effective solution for rainwater harvesting systems, gutter downpipes, and domestic drainage applications.
This product is intended for external use only and is not suitable for internal soil or waste systems. It integrates fully with the wider Wavin OsmaDrain system, allowing for seamless compatibility with other fittings, bends, gullies, and couplers.
The Wavin Osma 110mm Rainwater Adaptor (68mm Round Pipe) is commonly used in residential building sites, refurbishments, and maintenance projects where reliable drainage connections are needed at the interface between rainwater systems and underground pipework.
