Legionella Advice For Tenants

Guidance on Legionnaires’ Disease

What is Legionnaires’ Disease?

Legionnaires’ Disease is a potentially fatal pneumonia-like illness caused by Legionella bacteria. While everyone is susceptible to infection, certain groups are at higher risk, including:

• Individuals over 45 years of age
• Smokers and heavy drinkers
• People with chronic respiratory or kidney disease
• Diabetics
• Individuals with impaired immune systems

Where is Legionella Found?

Legionella bacteria are commonly found in natural water sources like rivers and lakes. They can also thrive in purpose-built water systems, including:

• Hot and cold water systems
• Storage tanks
• Pipework
• Taps and showers

How is it Spread?

The disease is contracted by inhaling small droplets of water (aerosols) that contain the bacteria. These aerosols can be generated by:

• Running taps and showers
• Flushing toilets

Who is Responsible?

As a tenant, you have a role in preventing Legionella contamination. Dorset Plumbing recommends the following precautions:

• Regularly clean showerheads and taps to prevent bacterial growth.
• Inform Dorset Plumbing if you notice debris or discolouration in the hot or cold water.

Additional Recommendations

To further reduce the risk of Legionella:

• Flush through showers and taps at least once a week, especially if they are used infrequently.
• Keep hot water on your boiler system at a temperature of 60°C or higher.
• Notify Dorset Plumbing if you plan to be away from the property for an extended period, so appropriate measures can be taken, such as flushing the system before your return.

By following these guidelines, you can help ensure your safety and that of others by minimising the risk of Legionnaires’ Disease.
