Abstract: A method of detecting stagnant water includes flowing a water in a pipe and producing electrical energy via the flow of the water. The electrical energy is stored in an energy store. A change of state of the energy store is detected and information about possible stagnation of the water is obtained from the change of state of the energy store. An apparatus for detecting stagnant drinking water includes a generator for producing electrical energy, an energy store for storing that energy, a control and analysis unit which detects the charge state of the energy store and a signal transmitter which emits a signal depending on the charge state of the energy store.

Abstract: Disclosed is a flow regulator, especially for insertion into a jet regulator in an outlet fixture, comprising an insertion member that is penetrated by at least one flow duct in an axial direction as well as a throttle element which forms a control gap along with the insertion member in order to allow a fluid to penetrate into the at least one flow duct. The aim of the invention is to create a flow regulator which allows for significantly greater durability during use while offering maximum ease of operation when fluid is discharged. Said aim is achieved by a flow regulator in which the throttle element is embodied as a dimensionally stable throttle cap that is supported in relation to the insertion member via an elastic spring element.
