The bog's stopped working properly. The flush water no longer makes its
way all the way round to the front of the bowl, although there seems to
be just as much water flowing just as fast as it ever did, so that the
front of the bowl never gets cleaned and paper tends not to get flushed
away properly either. Anyone had this problem?

That's interesting. I've got exactly the same problem with one of mine.

Mine's always been like it though. I've put it down to the fact that it's a
cheapo bog, the sort that derives from Portugal or where ever. Not my
choice - our predecessors put it in.

Perhaps it's a water pressure problem? I look forward to seeing any fixes.
