High cap gutters with (apparently) low cap downpipes??
 

Wandered into Wickes to buy a length of their 125mm 'high capacity'
gutter. No problem with that until I looked for a length of suitably
large downpipe. The high cap downpieces or whatever they are called fit
the same downpipes as the 112 mm low cap gutters, i.e. about 50mm
diameter at a guess. Is this right?

This might not be a problem but I intend draining the entire rear roof
area of my house via a single downpipe.

Even the operative in Wickes suggested that it was a little odd having
only one, small diameter, downpipe and that I should seek advice.

Well I guess the point is by it's very nature - being an enclosed tube -
down pipe can't overflow whereas guttering can. And guttering has a very
shallow angle whereas downpipe is at 90 dgrees from the horizontal and
therefore clears a lot quicker. I suppose the idea of the high capacity
guttering is that it won't will fill in a downpour long enough that
overspill doesn't occur until the down pipe can clear the water. Are there
any fluid dynamics bods in the group?

Thanks for the link and apologies for being particularly dense (it is
