The present invention relates to a device for indication of leakage in a liquid system, which includes liquid lines and a liquid filter that consists of a non-transparent upper portion (3) having flow paths (5, 6) for the supply of liquid to the filter and discharge of liquid from the filter, and a transparent lower portion (4) having a transparent casing (7) and a filter unit (11) positioned inside said casing (7). The invention also relates to a method for indication of leakage. It is significant for the device according to the present invention that an indicating channel (27) is connected to the inlet flow path (5), said indicating channel (27) extending below the upper portion (3) and having an outlet opening (31) that emerges in the lower portion (4) and being arranged to discharge supplied liquid so as to be visible to a persons eye and also indicate, visible to a persons eye, gas bubbles/air bubbles (39) that possibly are present.
