The apparatus has a switch device arranged in an electric circuit and connected with a switch e.g. pressure switch and liquid contact switch, and a sensor for detecting leakage of water. The switch device actuates a light source i.e. LED, such that lightness, color or blink frequency of light emitted from the source is varied or changed based on leakage volume of the water over time during a removal process. The source is arranged opposite to a water jet or at the water jet. The sensor detects liquid-specific parameters and sends signals to the switch device based on the parameters. The liquid-specific parameters are selected from a group consisting of flow rate, flow velocity, temperature, pH and/or hardness. |
