Legionella Checks

Legionella Checks

Along with PAT & Fixed appliance testing AEW can also complete legionella checks on the same visit. So, what’s involved ?

Flushing out water lines

This ensures stagnant water is not left too long in the pipework. This is essential when the property has not been used for a period of time. It also prevents any build up of any bacteria.

Recording the temperature of the hot and cold water lines

Completing this task confirms the required upper and lower temperature limits of both the hot and cold taps are achieved within the required time.
Cold < 20oC
Hot > 50oC

Disinfecting the shower head and hose with a bleach solution. This is good practise and demonstrates the landlord is proactive when it comes to preventing bacteria building up. It also helps with an audit trail for any local authority inquiry.
