[vc_row bg_type=”image”][vc_column][vc_column_text el_class=”introductiontext”]TMV\u2019s are valves that use a temperature sensitive element and blend hot and cold water to produce water that safeguards against scalding. This is producing water between 38\u00b0C and 46\u00b0C.[\/vc_column_text][vc_column_text]These temperatures however provide an environment in which legionella can multiply, thus increasing the risk of exposure. Due to this conflict, if the risk of scalding is insignificant then a TMV is not required. However in places where the risk of scalding is prospective, for example with the very young, elderly, infirm or mentally or physically disabled, a TMV is required.[\/vc_column_text][vc_column_text]<\/p>\n

Within healthcare and care homes there is a high risk of scalding where the water temperature is above 44\u00b0C. Due to the elderly being recognised as vulnerable individuals, who may not be able to recognise high temperatures, testing outlet temperatures is a necessary monitoring requirement.<\/p>\n
A Risk Assessment will help to determine the risk and advise if a TMV is required. However, due to the ambient temperatures that a TMV generates, annual, or otherwise specified, inspection, cleaning, descaling and disinfecting is required. It is important to assess\u00a0the requirement for a TMV against the risk of Legionella.<\/p>\n
