Hello; I need to vent the output from my tumber dryer. However there is
no direct access to an outside wall.

The best option would be to go stright up through the roof, but this
would involve a run of about 3m.

Currently I run it through the garage to a doorway. But I note that
quite a lot of water condenses in the plastic pipe. It needs emptied out
every few days of use. I did try placing a shower extractor fan halfway
along the pipe. But the hot air warped the plastic case and broke three
fans!

You'd be a lot better off with a condenser model which doesn't need
venting...

Can't you configure the ducting so it angles slightly downwards allowing
condensate to run away outside? Are you using concertina-like stuff or
the solid, smooth ducting (much more efficient)?

Hmmm; I thought they were even more enery inefficient!

Never considered that! I will have to look at the run again. But the
current duct runs across the floor and out a door. The most direct and
convienent root is up and out the roof. I was wondering if anybody had
done this sort of thing before, and if they had had to employed a sump
of some kind.

Throw it away and buy a proper condensing model that doesn't need venting.

I've done something similar but not for a tumble drier. This little
arrangement would prob suit your needs. You'd need to have ready access
to the bottle trap as it will tend to clog will wet fluff and you'll
need a connection to a drain for the condensate. Use fixed width font:
