Downpipe Angle

[Ivan in Oz]

Good People,

What is the Minimum Angle that a DownPipe can be?
OR
How far off Horizontal if you like:rolleyes:

The one feeding the Water Tank from the Gutters.

Also what is best to support it when in the open,
as in the small gap at the Top of the Verandah?
The Purple Lines in the Drawing:D

I hope to put the Tank about halfway between the Front and Rear gitters,
There is a 3 Metre Awning at the front:(

You can get away with 1 or 2 degrees off horizontal and support to the walls with some builders strapping fixed to the walls about every 1200mm.

Every 1200mm eh,
That means:2tsup:

Minimum fall for stormwater is 1:100 and the fellas are right with 1200 bracket spacings.
