Regular servicing of thermostatic mixing valves (TMVs) is paramount to ensure the safety and efficiency of hot water systems in various settings, including commercial, healthcare, hospitality, and residential environments. At Pipe Testing Services, we recognise the critical role TMVs play in preventing scalding hazards and controlling Legionella bacteria growth. Let’s delve deeper into why regular TMV servicing is essential and how it contributes to safety and compliance.

TMVs are designed to blend hot and cold water to deliver tempered water at a stable, pre-set temperature, thus preventing scalding while controlling Legionella proliferation. However, over time, TMVs can develop issues such as stuck valves, worn internal components, or excessive scale deposits, hindering their ability to regulate water temperature accurately. Scheduled TMV servicing is crucial to address these issues and ensure optimal valve function.
