sorry to harp on but if the warm water in the kitchen is coming from a hot water tank there is still a risk. See the following from the NHS website:
http://www.nhs.uk/Conditions/Legionnaires-disease/Pages/Prevention.aspx
The two most important factors for preventing an outbreak of Legionnaires' disease are:
temperature – any water in the system should either be cooled to below 20ºC (68ºF) or heated to above 60ºC (140ºF)
hygiene – the water should be kept free of any impurities and never allowed to stagnate (lose its freshness from not moving)
If you are an employer or a private landlord, you have a legal duty to ensure that all water systems in your premises are properly operated and maintained to prevent Legionnaires' disease or any other type of water-borne infection.
If you are a homeowner, you are responsible for the water systems in your house. In theory, these could also cause an outbreak of Legionnaires’ disease if they are not properly maintained. However, in practice, the risk is low if you keep your hot water at a high enough temperature and regularly use your water systems (to prevent stagnation).
Sorry couldn't resist adding this bit of info too:
Windscreen wiper water may be the cause of 20% of cases of Legionnaires' disease in England and Wales,” the BBC warned. It reported that the Health Protection Agency (HPA) has said that simply adding screenwash to wiper fluid kills the bacteria and could save lives.
