Hot Tubs and Legionella: What You Need to Know

Understanding Legionella Legionella bacteria naturally occur in freshwater environments but become problematic when they grow in man-made water systems like hot tubs. The bacteria multiply in warm water, particularly between 20°C and 45°C, making hot tubs an ideal breeding ground. Inhalation of contaminated water droplets or aerosols can lead to infection. Why Hot Tubs Are… Read more »

The Critical Importance of Water Hygiene Planned Preventative Maintenance (PPM) in Healthcare Settings

In healthcare environments—where vulnerable patients rely on safe, clean surroundings—water hygiene is not just a compliance issue; it’s a critical aspect of patient safety and infection control. Planned Preventative Maintenance (PPM) for water systems is an essential strategy to prevent microbial contamination, protect at-risk individuals, and meet stringent regulatory standards. What is Water Hygiene PPM?… Read more »

When Should Cold Water Storage Tanks Be Cleaned?

Water Sustainability and the Need for Conservation With the growing pressures of population expansion, urbanisation, and the global climate crisis, the demand for water resources is increasing at an unsustainable rate. Projections indicate that by 2050, an additional 4,000 million litres of water per day—equivalent to approximately 1,600 Olympic-sized swimming pools—will be required to meet… Read more »

Thermostatic Mixing Valves (TMVs): Understanding TMV2, TMV3 and Your Legal Responsibilities

Thermostatic Mixing Valves (TMVs) play a critical role in controlling water temperature and reducing the risk of scalding in both domestic and commercial buildings. In higher-risk environments such as healthcare, care homes and education settings, correct valve selection, installation and ongoing maintenance is not just best practice – it is a legal and moral responsibility….

How Passing TMVs Drive Legionella and Biofilm Formation

Passing TMVs create the exact conditions Legionella bacteria thrive in. The combined effects include: Once temperature control is lost, biofilm rapidly develops on internal pipe surfaces. Biofilm acts as: As biofilm thickens, it further restricts flow, worsening stagnation and creating a self-reinforcing cycle that accelerates colonisation. In many investigations of persistent Legionella positives, passing TMVs… Read more »
