A pressing tool for joining a pipe and a fitting, including two swivel elements for pressing the pipe and the fitting, a receiving region, formed between the swivel elements, for receiving the pipe and the fitting, at least one swivel axis for rotatably mounting the swivel elements, and a tensioning mechanism for pretensioning the pressing tool. The swivel elements can be swivelled towards one another about the at least one swivel axis to press the pipe and the fitting. In a first, closed position, the receiving region is narrower than in a second, open position, of the swivel elements, wherein the swivel elements are pretensioned towards the closed position by the tensioning mechanism. At least one holding device is provided for holding the swivel elements in the open position against the pretensioning force generated by the tensioning mechanism.

The invention relates to a method for automatic flushing of fluid lines, in particular potable water lines. The invention further relates to a device for automatic flushing of fluid lines, in particular potable water lines. The invention is based on the technical problem to provide a method and a device for automatic flushing which allows a flushing behaviour that is better-suited to the circumstances and more reliable. The technical problem is solved by a method for automatic flushing of at least one fluid line, in particular a potable water line, in which a temperature profile of the fluid is measured, in which the measured data are evaluated and in which the automatic flushing of the at least one fluid line is influenced by an outcome of the evaluation.
