We've got a (2 year old) UPVC downpipe leaking from the swan at the top. A roofer just told me he is convinced that the downpipe is full to the brim with moss and other debris, and when pushing the downpipe it feels very heavy, so I think he might be right.
The issue now is how about cleaning it out. The roofer said he doesn't work underground, and thinks that a proper job would need to break up the concrete at least around the underground (under-concrete) elbow . Are their any alternatives that might work?
I believe the downpipe is connected to a run of plastic drain pipe that runs with at least two 90 degree bends to the soil stack underneath the lounge which has new laminate flooring down (I saw this drain pipe when I layed the flooring 6month ago...). The only thing I can think of is a drain auger or chemical pipe unblockers.
