This sounds absolute nonsense to me. If it's not can you supply
proper references for what you are saying please.

These are the first paragraphs of statement shortly to be announced
by WRAS:

USE OF EDPM (STAINLESS STEEL BRAIDED) FLEXIBLE HOSES
(Materials in contact with water intended for drinking and other
domestic purposes)

FLEXIBLE HOSES
Non-WRAS approved extruded EPDM flexible hoses, (Stainless Steel
Braided), are completely unsuited for use with wholesome water because
they can support extensive microbial growth, impart a very strong
unpleasant taste and odour or release toxic substances to the drinking
water.
The Water Regulations Advisory Scheme is aware that concerns have been
raised by hose and tap manufacturers, health authorities, scientists
and plumbing installers regarding the effects of the materials used for
some flexible hoses, on the quality of water intended for drinking or
other domestic purposes. The concerns include the possibility that
these materials may encourage the growth of bacteria, which can be
harmful to health, especially the Legionella bacterium that causes
Legionnaires disease.
Legionnaires Disease is an opportunistic infection of the lung caused
primarily by inhaling Legionella bacteria contained in fine water
droplets or aerosols. It can be fatal, particularly by hospitalised
patients who are aged or immuno-compromised. Most reported cases of
Legionnaires disease are associated in large buildings where
temperature and flow patterns allow the bacteria to multiply. These
conditions may be found in under used taps and showers.


Now do you believe me?

Your reference to the fact I sell approved hoses is correct. I admitted
that. But I didnt tell you what brand did I?

I had kind of the opposite happen. I contracted a bacterial
infection which led to pneumonia. The hospital asked where I had
recently been. As it happened, I had been staying in a hotel where
the window of the room looked out over a roof where there was air
conditioning plant. They put two and two together and made 3. It
turned out not to be legionella. Nevertheless, I was in hospital for
a week with the pneumonia and remainder of the original bacterial
infection. It was debilitating, as you say - took over a month before
I could do much at all, a further three months to being reasonable but
best part of 9 to be back to normal.

http://www.wras.co.uk/Products_Default.asp says:

"The Water Regulations Advisory Scheme approves water fittings and
materials that meet the minimum requirements of the Water Supply (Water
Fittings) Regulations 1999 in England and Wales, The Water Byelaws 2000 in
Scotland and the Water Regulations in Northern Ireland. The approvals are
granted by a panel of experts from the Water Supply Industry who meet
regularly to review the fittings and the reports on any tests that have
been undertaken.

Non-Metallic Materials in contact with the water must comply with the
British Standard 6920, whilst the water fittings themselves must currently
conform to either:

i) An appropriate British Standard or another standard that provides a
similar level of protection and performance;

ii) A specification approved by the Regulator."

Leaving aside the apparent self-interest of the original post this web
site is not very clear about where advice stops and regulation starts.

Either the fitting MUST be approved before being connected to the water
supply or this is merely an advisory body with no teeth.

Reading the web page, it looks more like a consultancy firm.

If using non WRAS approved fittings was an offence I presume our regular
plumbing consultants would have backed up the original poster.

I also presume that large retailers would be unable to stock and supply
such things.

Given that the OP was quoting unpublished work allegedly for future
publication by WRAS this does seem to be a little incestuous.

Or yet another Troll :-(

Hoses on mains cold are carrying chlorinated potable cold water.
In all other cases the water is not exposed to the atmosphere or is cold

The risks must be vanishly small, i.e. Other risks are far more

I fail to see why cheap hoses would be any worse at harbouring germs
than expensive ones. Fall apart, yes, harbour germs probably not.

All this smells of scaremongering by the WRAS, trying to protect the
interests of British hose manufacturers. I have heard it all befo
"You are all gonna die if you use Chinese hoses/old coloured
cable/creosote/cheap underpants etc..etc"

How many proven cases of Legionella infection have there been due to
Chinese hoses? Contrast this with the number of cases from poorly
maintained air conditioning and you'll see there is no problem with
Chinese plumbing. Especially considering how many times a tap is used
during a day.

You aint seen the Electron Scan Photographs I have seen!
Could you accept that cheap extruded EDPM (synthetic rubber), made down
to a price and not made to any standard, can have a rough inner
surface. Could you accept that dearer EDPM hose, made to quality
standards, can be made with a smooth inner surface and tested as such
and against harbouring biofilms by an independant laboratory?

If you cannot accept that I hope it is not your immune compromised
Mother/Child/family member that suffers.

Go to an earlier posting in this thread by Nigel Molesworth. He got
mild legionella he says, from a Spa Bath. Now Spa Baths use a lot of
Flexible hoses to achieve the flow of water to various outlets. What a
coincidence! I would have money that these were the root cause of his
illness.

I wonder why all the flexible hoses were recently removed from
Worcester Royal Infirmary at great cost and have been banned in PFI
Hospitals built by a certain PFI consortium? I wonder why all the
flexible hoses were removed from the University of Essex Student
Accommodation Block in Colchester? Perhaps they enjoyed pulling them
out and replacing them? There are others.

When I have permission to publish the photos I will post them in this
group. Until then carry on taking the risks gentlemen.

cause. Legionella is caused by water droplets, there are quite a few
of these in a spa.

And pray where do the water droplets come from? Does the legionella
suddenly appear in the air and attach itself to the water droplets? No!
the water that is eventually turned into droplets comes up a supply
pipe. If that pipe has a soft, porous surface internally, (cheap EDPM
pipe), it will harbour biofilms, (trapped in the pores). The biofilms
harbour loads of nasties, pseudomonas, mycobacters, Legionella etc

I suggest you do a bit of reading up on legionella before suggesting I
am a ****. You are the **** that caught legionella. I wouldnt be seen
dead in a spa pool.

You lot remind me of medieval people who thought that dysentry etc was
caused by bad smells. They called the Doctor who traced the real cause
a **** at the time.

Have you seen just how 'rough' the average pipe is in a hard water area
after a short time in use?

We are not talking 'rough' we are talking porosity. Hidden pores that
are sometimes self closing. Acting like sponges.

However good your claims, this one doesn't hold water. The behaviour of

This was a PFI Hospital. Do you know what that is? A private consortium
that builds and maintains hospitals for a profit. They just love

If using non WRAS approved fittings was an offence I presume our regular

For your info: Following is extract from the Regulations: (With respect
I am coming to the conclusion that your regular plumbing contributors
wouldnt know the regulations if they fell on them)

1 Plumbing systems to comply

Plumbing systems must be designed, installed and maintained to meet the
regulations' requirements. Plumbing materials and fittings must be of
a suitable standard. It is not illegal to sell unsuitable fittings and
appliances but to install one would be illegal, so check suitability
before purchase. The regulations list the standards which fittings must
meet and the Water Fittings and Materials Directory, published by the
Water Regulations Advisory Scheme (WRAS)

Reading the web page, it looks more like a consultancy firm.

If you would care to read it again you will see it is a Govmnt funded
scheme to protect the health of the public when it comes to the
conveyance of water.

I think you should take your smooth hoses and shove them up your rectum,
where the indisputable slick quality of their interiors should protect
you from bowel cancer and diverticulitis, as well as allowing you to
**** perfectly formed turds, not to mention making you walk with a
peculiarly mincing gait that will make you a target for any gay basher
