How often should little-used outlets be flushed?
HSE guidance is to run a programme of regular flushing for infrequently used outlets, weekly. Flush through and purge to drain without releasing aerosols. Showerheads should be dismantled, cleaned and descaled quarterly, or as the risk assessment decides. HSE's technical guidance adds that once flushing has started it has to be kept up and logged.

Legionella flushing record FAQs
Which outlets need flushing?
Any outlet that is not used regularly, such as taps and showers in empty rooms, external taps and hoses. HSE's technical guidance says equipment not used for seven days or more should be on the flushing regime. The legionella risk assessment should list them, and the form asks each week whether any outlet has started or stopped being used so the list stays right.
How do I flush without creating spray?
HSE says to flush through and purge to drain without releasing aerosols. For a shower, remove the head or cover it with a bag, and run the water at a low flow. The form asks for each outlet whether it was done without creating spray.
How long should each outlet be flushed?
HSE's technical guidance describes weekly flushing for several minutes, flushing until the temperature at the outlet settles and is comparable to the supply water. Your risk assessment sets the regime. The form records the minutes and, if you measure it, the temperature reached.
How often should showerheads be cleaned?
HSE says to dismantle, clean and descale showerheads quarterly, or as determined by the risk assessment. The form records the last cleaning date for each shower and warns when it is more than three months ago.
What if an outlet could not be flushed?
Answer No for that outlet and say why, for example a room that was locked or a tap isolated for the winter. The form counts the outlets not flushed, so they can be followed up.
How is this different from the temperature log?
The temperature log records monthly readings at sentinel outlets. This record covers weekly flushing of little-used outlets. Most premises with a legionella risk assessment need both.
