Try to locate the obstruction visually. Sometimes, leaves, twigs and other debris can become lodged in the opening of the downpipe or close to the top of the pipe. If you are able to identify the source of the problem, try using a length of wire that has one end bent into a hook shape to hook the offending material out of the downpipe. Then flush the downpipe using buckets of water to remove any gunk that remains.
A garden hose can also be helpful for clearing obstructions close to the downpipe's opening. A powerful stream of water can dislodge gunk that is stuck in the bends and corners of your downpipes.

After cleaning, cut a length of repair tape a few centimetres larger than the width of the downpipe. Then, remove the paper backing. Carefully wrap the tape around the joint, ensuring that it is able to cover any crack or hole completely and that the ends overlap. Press the tape with your fingers to mold it into the joint and allow it to dry.
Seals on guttering can also be worn out or damaged over time. This can be caused by damage to the guttering caused by falling debris, from ladders being used against it, or from collisions with buildings or vehicles. It could also be the result of improper installation, especially when replacing a downpipe, or due to a guttering system that is not aligned properly or having the wrong size components fitted to it.

Then, you should let the gutter length go that is positioned over the affected seal and make sure it is removed from the adjoining section.
