Arrived to do this one today only to find I my plumbing snake wasn't in the van. Must have left it at a previous job. Oops! As per usual the downspout was blocked so dug what I could out by hand. Sod's law the joints had been glued so only option was to try and unblock the bends with something I had in the van. Had a bit of a brainwave whilst looking about in the back of the van so decided to cut a bit off me minibore hose reel that so happened worked a treat. Now all I have to do is take off the bit of hose to keep as a downspout unblocker and put me hose connector back on me hose reel.
