Fitting a angle joint without leaks — Freeflow Black Round Gutter 90 Degree Angle Joint
Most leaks at a angle joint 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 Freeflow Black Round Gutter 90 Degree Angle Joint 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.
