Downspouts may break loose from the gutter outlet or between sections. This often happens when elbows in the sections become clogged with debris.
Take the sections apart and clean out the debris. Then, to refasten them, push the downspout sections and/or elbows together, drill pilot holes if necessary, and fasten them with two 3/8-inch #8 galvanized sheet metal screws. (Don’t use longer screws because debris will hang on them.) Be sure the anchor straps that hold the downspouts to the wall are secure.
Fasten the top downspout to the S-curve outlet with one or two screws at each joint (using only one screw makes them easier to take down for regular cleaning).
