Default Legionella Bacteria

In my last job, I had to check all static water storage each month for traces of Legionella. Well not actually check for the bacteria, but assume it was present and treat the water accordingly. The principal site was the central heating system, where like a NOVA processor some sections heated up and cooled down at regular intervals, but not to a temperature enough to kill it off.

In the summer, even cold water pipes had to be checked and run off for around 20 minutes once a month.
