A 90-degree overflow bend (often called a knuckle bend) is a fundamental component used to change the direction of 21.5mm piping at a right angle. These fittings are indispensable for routing overflow lines from toilet cisterns and cold water storage tanks, as well as for managing the discharge from high-efficiency condensing boilers.
In high-risk areas where a leak could cause significant water damage, professionals prefer solvent weld fittings over push-fit alternatives. By using solvent cement, the pipe and the bend are fused at a molecular level, creating a “welded” joint. This ensures that the system can handle temperature fluctuations and physical vibrations without the risk of the joint pulling apart over time.
Our white overflow bends feature a smooth internal bore. This design is critical for maintaining high flow rates and preventing the “snagging” of debris or lime-scale buildup in the corner of the pipe run. Whether you are navigating a corner of a building or connecting a pipe to an external discharge point, this fitting provides a professional, “fit-and-forget” solution.
