When it comes to outside bib taps it's not just the cold that we have to safeguard against. When we have a volume of water that is not used regularly, there is a risk of water stagnation and bacterial growth.
Legionella bacteria takes 72 hours to proliferate in stagnant water over 20°c and when transferred to a susceptible host becomes Legionnaires disease. Legionnaires disease is a form of pneumonia and has extreme flu like symptoms, which can be fatal. The most common way to contract it is through inhalation of small water droplets which are generated in showers, hot tubs and sprinklers/hosepipes.
To remove this risk you have to guarantee regular water movement or remove the 'under used outlet (ACoP L8). With the KEMPER FROSTI tap automatically eliminates this risk
