Run all taps individually, starting with the tap nearest to where the water enters the building and move systematically to the most distant outlet. Run until the water is clear and feels cool to the touch.
Where water is stored, storage cisterns should be emptied and filled with water direct from the incoming supply, before flushing the taps.
Flushing should be carried out in a way which minimises aerosols (water droplets in the air) e.g. by removing showerheads prior to flushing. This reduces the risks of Legionella transmission.
Safety considerations should be given to those doing the flushing, including wearing appropriate PPE.
Ensure all appliances are thoroughly flushed through before use, using manufacturer’s instruction manuals e.g. dishwashers, water fountains
If the property has internal filters or water softeners, these should be checked to ensure they are working correctly, as outlined in the manufacturer’s instruction manual.
