    Hygiene Grundfos pressure pump systems are functionally tested by running water through the system. During the test, Grundfos continuously surveys the quality of the test water. Since it is not possible to completely drain and dry the system after the test, the system must be rinsed or flushed thoroughly before being used for drinking water applications, due to risk of bacteria growth.
