If downspout is clogged, wouldn't the waterflow spill over to the
sides completely rather than just that sagged/bent part? I just
checked the downspout and it does have some debris, but the water
still flows out pretty well.



I had a similar problem. The gutter looked clear and there was water
exiting the downspout. But I pulled out several handfulls of packed
dead leave from the 'S' bend in the downspot. The gutter overflows
when these leaves back up water due to a heavy downpour.
