About Legionnaires' disease
Legionnaires’ disease is a potentially fatal form of pneumonia caused by legionella bacteria. Legionella bacteria can multiply in hot or cold water systems, and is transmitted by aerosol, e.g. in spray from showers and taps. Legionella bacterium remains dormant at low temperatures. It thrives at temperatures in the range 20⁰C – 45⁰C.
Maintaining cold water temperatures below 20⁰C and hot water temperatures above 60⁰C (cylinder), or 50⁰C (outlets) is a simple and effective means of preventing the proliferation of legionella bacteria within the system.
As tenants you should:
Ensure that water is regularly circulated throughout your system.
Maintain the temperature of water at the outlets below 20⁰C for cold and above 50⁰C for hot. – If you feel your hot water is not reaching a high enough temperature please report this to our office.
You must clean your showers and taps, to prevent the build up of limescale and disinfect regularly – it is recommended that this is done quarterly - with the correct cleaning products. For routine and regular cleaning of your shower head and hose:
- Physically clean the head with a soft brush to remove loose deposits or soap scum
- Use a sturdy plastic bucket. Immerse the shower heads and hoses in an appropriate cleaning product covering the shower heads and hoses.
- Leave to soak for around 15 minutes.
- Any remaining loose scale can be removed by gentle rubbing.
- Rinse thoroughly with clean water.
- Examine fittings to confirm cleanliness
You MUST NOT:
Interfere / adjust the temperature controls of your boiler or hot water cylinder. Please contact our office on 0113 357 2262, if you think the system should be checked.
