Hello C Man, thanks for the interest. Yes, thats 1 x 90 ml down pipe for 14 lineal meters of guttering. It carries the run off from 14 x 7 meters of roof catchment, where 4 meters of the 7 are @ 30 degrees, and the other 3 meters directly onto the gutter, are at 5 degrees. We wanted to do one thing at a time (taking a leaf out of my own book there!) and fix the glaringly obvious first and see what happens before getting serious and looking to do more stuff.....!
