    THE LEGAL REQUIREMENT
    It is a legal requirement that flexible hoses are assessed by a competent laboratory for their compliance with BS6920: Parts 1 to 3. These tests assess the likelihood of the material being able to support microbiological growth and leach chemicals into the water with which they are in contact – chemicals which might either act as nutrients for bacteria, cause an adverse effect on the aesthetic qualities of the water (e.g. give it taste, odour, colour or turbidity) or be toxic to humans.
    Installers (plumbers) and Users (building managers) of water fittings are liable to prosecution for non- compliance with the Regulations. It is essential that unsuitable hoses are not used in wholesome water systems. Under the Regulations and Health and Safety legislation, the safeguard against prosecution for the use of unsuitable fittings leading to harmful effects on health is to insist on the use of fittings which have been assessed and shown to be satisfactory.

    I remember it being an issue in health care settings down here, there was a HTM on it somewhere. Ill try and find it. Think they just use regular documented flushing to overcome the problem. Its to do with the rubber lining on cheap flexible hoses, wras tested ones are ok.

    hospitals have had a purge on cheap flexis in the past due to the ability of bugs to breed in them, was good money for a couple of firms down here
