The Dangers of Legionnaires Disease

Here in the UK, we’re used to being able to access fresh and clean drinking water from our taps. However, this can make us complacent to the invisible dangers that present themselves in faulty plumbing systems. One of the more serious risks from unclean water is an infection known as legionnaires disease.

While it’s an uncommon affliction, legionnaires disease can be extremely dangerous if contracted. With this in mind, it’s important to have an understanding of the disease and how it grows and spreads. As expert plumbers, with experience in carrying out comprehensive plumbing risk assessments, we know a thing or two about the dangers of legionnaires, which is why we’ve put together this handy guide on the disease.

An Overview

Legionnaires disease, also known as legionella, is a severe and potentially lethal form of pneumonia which infects an individual’s lungs. The bacterium can be found in potable and non-potable water and even in the soil. However, it is usually contracted by an individual inhaling infected water droplets.

Because of the fact it relies on water to be transmitted, one of the more common places that legionella is found to thrive is in plumbing systems that have not been well maintained. Air conditioning that hasn’t been properly and regularly cleaned can also pose a risk.


As the legionella bacteria primarily affects the lungs, many of the more intense symptoms are connected with the respiratory system. This includes shortness of breath, a cough, and severe chest pains. However, the first signs of an infection are somewhat milder and can be confused with the flu, such as a headache and fever.

If you have a cough that doesn’t seem to be going away and is causing you problems like the ones mentioned above, it is vital that you call 111 to get advice from a health professional. Tackling the issue quickly is the best way to ensure a complete recovery.
