There's very little waste, as well. It's a nice system.
(Oh, yes, we have four levels of gutter, because we have four levels of house. The bottom level's floor is level with the ground in front - that's garage and basement - and in back, were it not for the retaining wall, only the top floor would be above ground. As it is, the top floor and half the main level are above ground, and the two levels below that are underground. The two gutter levels you can see in the photo are on the bottom two levels; the next up is the main level, then there's another above that. The house isn't nearly as so big as that'd make you think, it's just built into a crazy steep hill and includes its own massive retaining wall to make this work.)
And that's what I did on my day off!
