Interesting post Herbie.

Well, personally I never drink the water that comes directly into the caravan, we have a tank purely for drinking which has a two stage filter/purifier system. (yes filled from standpipes but filtered and purified before drinking)

The shower water off of the hot water tank, never been tempted to drink any of it, and when it comes to rinsing after a brush of the gnashers, excuse the expression, but I spit and don't swallow

Water tanks are drained when not in use and I run a de-algie tablet through them and if I fill them for bush use then they get steri-tabed just in case I happen to get a bit in my mouth. 
If we are going bush I always make sure that the 90 litre drinking water (seperate tank) is full, plus we carry about 40 litres of emergency rations in gerry's.

But equally, I also agree that we should ingest some bacteria as jeti says.

That's my waterworks discussed

Mark I could be wrong again but I think it's breathing the spores rather than drinking the bacteria is the problem.

 Correct, but in a shower that is exactly what happens, they are breathed into the lungs.

 

Chlorinate all water in your tanks (to kill any bugs) and don't keep water warm (breeding rates are very high in warm water). Hot or cold is best.

I have two water filters fitted to my van one out side and one connected to the water over the sink.But from what I have been reading this alone does not stop the bacteria from building up inside water tanks /pipes /shower heads/taps/even the hoses can contain the bacteria.I have been reading about a product called Floe that appears to be the bees knees ,was wondering has anyone on here heard or used this product.And yes the way Legionnaires is contracted is from breathing in the air containing the bacteria.

My RV hot water system runs to 70 degrees so should be adequate, apart from which I filter with a half micron filter and treat All the water going into my tanks with a colloidal silver additive as well.

Sounds like it's some bloody pencil pusher saving money without having the knowledge to actually know the pitfalls, that ordered the water heating in the hospital to be reduced to 50 degrees

No doubt they will be taken to court for compensation which will take money from where it's needed. Actual patient care.

The doctors and nurses who do tremendous work are not at fault, it's the bloody administration yet again.

 The reason hot water is regulated to be below 50 degrees C is to prevent scalds and there is a far greater risk of being scalded with tap water above 50 degrees than there is of contracting legionella. And this would apply even more to aged care facilities and hospitals. Temperature is not the only nor the best means of controlling legionella bacterium. The breeding temperatures are between a range of 30 and 60 degrees so one could as easily control the bug by chilling the water and having cold showers. And since a shower at 60 degrees would scald you, chilling would seem to be a better option if you're going to rely on water temperature as a control. Biocides, filtration, water system cleaning and maintenance and other processes are far better ways of preventing a build up of the bacterium to cronic levels.

The hot water system you're running would certainly protect you from the legionella bacterium but the risk of being scalded by a hot water system operating at 70 degrees is pretty high and not something I would be risking. I would also be checking what plumbing was installed in the RV as many plastics and the glues used to bond them begin to degrade at far lower temperatures.

For what its worth .I have been involved in Industrial Plumbing for nearly half a century,to date I have never Known this disease to surface from a domestic scource.Invariably it is associated with industrial cooling towers .
Our trade newsletters keep us up to speed with the points of source and I have never heard of it to arise from anything other than commercial or industrial .

The water filters we use to protect us can and do become breading grounds for nasty little monsters.

What do people do to clean their water filters?

How often do you clean/replace your filters?

 I'm with you  ... Just another scare that we needn't worry about.  

Just like the risk to the general public from the Telstra pits during the NBN rollout.  It too is a non event.

But the media will beat them up for all they're worth & get us all worrying ... for a couple of days until they move on to the next imagined disaster.

 The reason I posted the question regarding the topic re Legionnaires Disease in RVs is that I was reading some emails re from my place of work regarding the out brake of the disease ( and the procedures that are going to take place in our work inviro ) and the World Health Organization had RVs of all types were on their list. Plus c/van parks.
