The downpipe could be loosened due to a faulty wall connector. If the downpipe that is leaking is plastic, it could be that the retaining clip is loose and must be replaced. PEX leaks can be caused by an uncrimped connector that isn't sealed completely. A PEX Crimping Tool and the test gauge that's typically included with the tool can be used to fix this problem.

Pipe repair clamps are used to fix leaking downpipe joints. They are available in various sizes based on gutter width. These clamps use the gasket of a metal with an elastic band to repair leaks along the length or end of a pipe.
