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?
