Begin by identifying the blockage visually. Sometimes leaves, twigs and other debris may get stuck in the downpipe's opening, or near the pipe's top. If you can see the culprit, try using a length of wire with one end bent into an angular hook to pull the material that is causing trouble out of the downpipe. Then flush the downpipe by using buckets of water to wash away any remaining gunk.
A garden hose can also be helpful in removing obstructions near the downpipe opening. A strong stream of water can help to remove gunk that is stuck in the bends and corners of your downpipes, especially when they're made of cast iron.

Then, you need to remove the gutter section that is located over the seal that is damaged and lift it off of the adjacent section.
Replace the damaged section
