We have a single-storey pitched roof that falls down to gutters. The gutter
falls from right to left across the ~10m wide wall. At the left corner
there's a downpipe, a water butt connection, and then an angled piece of
drainpipe to take the water into an external kitchen drain that's roughly in
the middle of the wall.

I'm thinking of rejigging this so the gutters drain into a downpipe in the
middle that leads more-or-less directly towards the drain (well, slightly
offset to go around a window immediately above the drain).

Any pitfalls to expect doing this? Is there neat way to make a piece of
guttering fall in the opposite direction without drilling new holes in the
fascia for brackets slightly higher up? Can you maybe get brackets of
variable height or something?

Thanks

There's a standard type of variable height bracket. One part is
basically a length of galvanised steel strip (about 20 x 5 mm at a
guess). This normally comes with a "point" at one end, you drill a pilot
hole in a mortar course and hammer it in horizontally. Or, you can bend
it at 90 degrees as required, drill two suitable holes in the wall and
plug and screw. The other part is a semicircular steel strip that fits
under the guttering, with a length of studding welded in the middle. The
studding goes vertically through a suitable hole in the first bit of
strip, and height is adjusted with the aid of two nuts (one each side of
the horizontal strip).

This is a good way to do it if the vertical height of the facias is not
large enough, or perhaps if the facias are showing signs of age.
