Condensation, damp, mould and legionella, are risks that can impact any household. It is important to understand the difference between them so that you can effectively treat the problem.

Damp, condensation and mould growth

One of the most common causes of damp in homes is condensation, and most homes will suffer from condensation at some point. Certain activities can increase the problem such as cooking and drying clothes indoors.

Legionella

Domestic hot and cold-water systems can provide an environment where legionella bacteria may grow. ‘Legionnaires’ Disease’ is potentially serious form of pneumonia, together with other less severe health conditions. It is caused by inhalation of very small droplets (aerosol) of contaminated water containing legionella bacteria. With a few simple controls, the risk of ill health is extremely low.

Simple tips to assist the control of legionella bacteria.

Important, make sure that:

  • Hot water in the system remains hot
  • Cold water is kept cold
  • The water is kept circulated

In particular, it is important that you:

  • Do not interfere with the settings on your boiler or hot water system. The hot water should be set so that the water is heated up to 60oC.

A system will need a check if:

  • The cold water is still running warm after you have initially run off any water which may have accumulated in the pipes. It should not be above 20oC.
  • There are any problems, debris or discolouration in the water.
  • The boiler or hot water tank is not working properly, particularly if the water is not coming out of the taps at a sufficiently high temperature. It should come out at a temperature of 50oC after it has run for a minute at the latest.

If you have a shower:

  • If it only used occasionally, then flush it through by running it for at least two minutes every week. Keep out of the way whilst this is being done as far as possible.
  • Clean the shower head, de-scale and disinfect it at least once every six months.

Where a property is left vacant for any time, make sure that both hot and cold water systems are flushed through by running all outlets for at least two minutes.
