Any other suggestions most welcome!

You can probably get the hose up up the downpipe by feeding from the
bottom - the downpipe will stop the hose folding back on itself.

If you have room at the bottom of the downpipeÂ* a bare end of a hose may
be sufficient to clear a blockage but ideally a nozzle set to the
narrowest higher pressure jet will work a lot better.Â* Feed the hose up
before turning on the water.

You don't say if the downpipe has push-fit or solvent welded fittings.
If the former you may be able to take off an angled shoe at the bottom
of the downpipe to give you more room.

If you have moss on the roof the blockage is probably that. If so just
clearing the downpipe may not be a long time cure as the moss in the
gutter will migrate to the downpipe again in heavy rainfall.


Good idea but push the hose up with water turned on. The pressure stops
it kinking.
