Also, since it's designed to carry water, the joints should be
waterproof too :-)

Starting high, then coming down is ok, it's the coming back up again
that creates a 'pocket' where water can't drain from. Ideally you'd want
a continuous fall from the point it leaves the house, to where you take
your cables out of the end of the pipe. Any collected water can then
just run out.

Clearly not a job for any self-respecting UKHA-er - how would any of us
fit into that space. Small child, now that's what you need ;-)

Any excuse for using a power tool :-)
