    What does the term Category CAT5 mean?

    The Water Supply (Water Fitting) Regulations 1999 provides five backflow prevention categories dependent on the risk level of the water use.

    The regulations require back-flow prevention devices to prevent the water on the premises being drawn backward into the public drinking water supply. Backflow may occur in a number of situations, including burst pipes in the street or cross connection of the mains water supply with pressurised supplies on the premises. An assessment needs to be made of the potential dangers to health of the backflow – if the backflow water comes from a butcher’s shop, it is more likely to be contaminated than a newsagent.

    In the legislation, fluid risk category 5 covers the following areas:

    Fluid which represents a serious health hazard because of the concentration of pathogenic organisms, radioactive or very toxic substances, including any fluid which contains –

    faecal material or other human waste:

    butchery or other animal waste: or

    pathogens from any other source.

    To provide category 5 compliance, a break tank has a category ‘AB’ air-gap fitted and a pump which re-pressurises the water.


    Pease note this is non-returnable due to possible contamination issues
