Generally, a well-thought-out pipe network geometry will also contribute to the system being extensively rinsed when used regularly. In order to avoid stagnations, main consumers, such as the washstand or toilet, should be placed at the end of pipes on each floor. Series or ring installations are preferable, so that a rinsing of the pipes on the floor is triggered by the tapping. Less used appliances should be looped in where possible. The liNear rinse simulation displays this process clearly. The software simulates the rinsing of the pipes during a tapping, because concentrations of the legionella endanger everyone, not just those in risk groups such as babies, the elderly and hospital patients.
