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?
