Regulations require employers to monitor and maintain domestic hot and cold-water systems to reduce the risk from legionella bacteria. The employer should keep suitable records of the tasks carried out and they should be reviewed at least annually.
Hot and cold-water systems include cold-water tanks, calorifiers, water heaters, showers, Thermostatic Mixing Valves, expansion vessels etc. These need to be regularly inspected for temperature, cleanliness/operation and the water should be kept moving through the water system, so it does not stagnate.
