Generally you will find a property has a cold water storage tank if the central heating boiler is a non combi boiler. You would normally find the cold water storage tank in the loft area or on the top floor of the property in a cupboard/airing cupboard.

Landlord Advisory (if there is a cold water storage tank) : Please ensure that a tightly fitted lid is present and the tank is free from debris at the bottom of the tank and there is no build up of sediment, scale or corrosion debris which may harbour bacteria. Legionella feeds off these matters. If the property has been unoccupied for a long period we recommend the water tank is emptied and cleaned prior to any new tenant moving into the property.

Note : If the cold water temperature is running above 20°c you should take action to remedy this situation immediately. This will indicate a RISK of Legionella.

Note. If the hot water temperature is running over 60°c this could cause scalding. Please adjust to around 58°c to 60°c

The term 'dead legs' refers to lengths of pipework which are not in use but are still connected to the water system. An example may be a washing machine connection which is no longer in use. These lengths of pipework store stagnant water and this can lead to a build up of legionella in certain circumstances. If this pipework is then disturbed and the water sprays into the face of a tenant/landlord or contractor there may be a risk of legionella and illness. We recommend (where possible) that all dead legs are removed from the property water system.
