Legionnaires’ disease is a potentially fatal type of pneumonia, contracted by inhaling airborne water droplets containing viable Legionella bacteria. Such droplets can be created by hot and cold water outlets, including taps and shower heads. In certain conditions the bacteria may multiply where temperatures are between 20-45°C. Avoiding bacteria harmful to our health is extremely important, especially with the current concerns over the spread of Coronavirus. 

Anyone can develop Legionnaires’ disease, but the elderly, smokers, alcoholics and those with cancer, diabetes or chronic respiratory or kidney disease are at more risk.

To reduce the risk of bacteria being able to grow in your hot and cold water systems, please ensure that the hot and cold water outlets are used regularly. Where there are outlets (taps, showers, toilets etc.) that are not in use regularly, weekly flushing of these outlets for several minutes can significantly reduce the risk of building harmful bacteria. 

Reduce the risk of Legionnaires’ disease

These are some simple steps you can take to reduce the risk of this bacteria growing in your hot and cold water systems at home: 

  • Make sure both hot and cold water outlets are used regularly
  • Where they are not in regular use, flush the toilet or run the tap for several minutes each week
