Shower Head Legionella Control
Shower Head Cleaning and Descaling
Health and Safety Executive ACOP and Guidance L8 states:
“The presence of sediment, sludge, scale and other material within the system, together with biofilms, are also thought to play an important role in harbouring and providing favourable conditions in which the Legionella bacteria may grow. A biofilm is a thin layer of micro-organisms that may form a slime on the surfaces in contact with water. Such biofilms, sludge and scale can protect legionella bacteria from temperatures and other biocides that would otherwise kill or inhibit these organisms if they were freely suspended in the water.”
Lubron engineers are fully trained to remove, dismantle and clean all designs of showerheads as part of a routine service package.
To ensure that showerheads are left scale free and any underlying biofilm and bacteria are removed Lubron utilise “Showerhead +” a combined disinfectant and descaling chemical
How often should showerheads be cleaned?
Showerheads and hoses should be cleaned every 3 months (quarterly)
Why do I need to clean showerheads every quarter?
The presence of sediment, sludge, scale and other material within the system, together with biofilms, are also thought to play an important role in harbouring and providing favourable conditions in which the Legionella bacteria may grow.
What technologies are available with showerhead maintenance?
The traditional method is to manually clean and disinfect the showerhead every three months and record all works in the water hygiene logbook. This task can be carried out by a Lubron engineer alternatively after training can be carried out by site staff. There are also technology available to help the task;
Colour coded replaceable heads – especially helpfully when dealing with important sites with many heads such as healthcare environments
Legionella filter heads – these heads filter out any harmful bacteria allowing the shower to continue to be used. These filters need to be replaced every 1 to 3 months
Self flushing head – these temperature activated heads flush the shower before operating lowering the stagnant water risk
What should I do if my shower is not used?
Showers create an aerosol which increases the Legionella risk therefore at least weekly usage is required. If the shower is used infrequently at least weekly flushing is required, your risk assessment will also detail flushing frequency
