Share "Downspouts Need Unclogging Too"
If the flat surface of your gutters is clogged, it stands to reason that the downspout, where debris can easily go, could be clogged even worse. If you already had your power washer out for your house, deck or gutters, it might be a good idea to use it for the downspout as well.
After you remove the downspouts from the gutters, check it to see by hand (with gloves) if there are any clogs at either end of the tubing. This may be the extent of your problem but you never know, so we’ll proceed.
Using a long brush or a pipe snake slowly put it down each end of the downspout to see what you can pull out.
It’s now time to use the power washer if you could reach the clog or to just clean out any extra debris. Put the nozzle slightly down the tube and fire away. Make sure the other end is not in an area where you mind a lot of water being.
