Fitting a offset bend without leaks — FloPlast 65mm Square Downpipe Adjustable Offset Bend
Most leaks at a offset bend come from a seal that wasn't seated fully before the fitting was clipped home, or from over-tightening a solvent-free push-fit joint. Clean the mating surfaces of grit and old sealant first, offer the FloPlast 65mm Square Downpipe Adjustable Offset Bend up square, and push until it clicks — forcing an angled fitting distorts the seal and is the most common cause of a slow drip after a repair.
