Polypipe SD46 Rainwater Adaptor – 110mm to 68mm Offset Reducer
The Polypipe SD46 rainwater adaptor connects a 68mm round rainwater downpipe to a compatible 110mm socketed soil or drainage fitting. Manufactured from durable PVCu, the offset body allows improved alignment between the downpipe and drainage connection, making installation quicker and neater on domestic rainwater systems.

The Polypipe SD46 rainwater adaptor is designed with a 110mm plain spigot and a 68mm round rainwater socket. Unlike a straight concentric reducer, the offset design allows the rainwater downpipe to line up more easily with the drainage connection.
