Anyone else concerned about water that has been left in a hosepipe and

if the hose is set to mist, I wonder if there's a risk of something
nasty being inhaled. Legionnaires?

The Dutch are worried about water left in public showers.

Yes, and so are we! Athletes foot is just one annoyance. There are many
others, dare I say Hep...

They find legionnaires disease in the shower water fairly often.

Well, yes, they would - it is incredibly widespread. The point
about domestic use is that, if the conditions are right for it to
reproduce in a hosepipe, they almost certainly are in the house's
water tanks and pipes.

It is also killed by quite low temperatures, so is unlikely to
survive if a hosepipe gets hot in the sun - but, in the UK, that
will be rare. So, there IS a risk, but a low risk compared to
that posed by showers and other water use in the house.

Also, it's rarely a threat to healthy individuals, like so many
of the things that the tabloid press make such a fuss about (e.g.
ordinary salmonella).
