After carrying out your inspection and noticed any damages such as cracks and holes, you might wanna have closer checks on your downpipes to. Problems with downpipes often manifest as leaks which do not resolve by cleaning. If you have cleaned the main system of guttering but still have a leak, it is probable that it is a problem with the downpipes. Therefore, remove the elbow joint connection and see if there are any clogs in there. A garden hose or a plumber’s snake can be used for manually breaking the clog.
