The 110 - 68mm Solid uPVC Underground to Rainwater Adaptor is a specialized transition fitting designed to bridge the gap between below-ground drainage networks and above-ground rainwater systems. Manufactured from tough, high-impact unplasticized polyvinyl chloride, this adaptor is engineered to withstand outdoor weathering, UV exposure, and ground pressure. It provides a reliable and watertight link, ensuring that rainwater collected from roof guttering is safely and efficiently transferred from downpipes into the subterranean drainage network.
 
Featuring a stepped reduction profile, the adaptor securely connects a standard 68mm rainwater downpipe to a 110mm underground drainage pipe or fitting. This transition prevents leaks, reduces the risk of water splashing around building foundations, and protects the surrounding masonry from moisture damage. Its sturdy construction maintains structural stability under external forces, ensuring a secure and dependable connection throughout the changing seasons.
 
Designed for straightforward installation, the adaptor allows for a quick and secure push-fit or slot-in connection, saving time on site without requiring specialized welding tools. The smooth internal flow path helps prevent leaves, twigs, and debris from snagging at the junction, maintaining an efficient flow of surface water. Whether you are installing a new rainwater management system or upgrading existing property drainage, this solid uPVC adaptor delivers professional-grade versatility and long-term reliability.
