Fall in guttering

[Tim Watts]

3 rectangular bays to get around, downpipe at each end, direct width about 11m so guttering is about 15m from end to end.

Do folk reckon a 1" difference in height bewteen the middle and both ends (so 25mm over about 7-8m gutter) is a reasonable figure?

Cheers,

Tim

No. 1:100 if you can. Or it will silt up

Thanks - that's doable.
