<p>The present invention provides a piping system having functions of preventing water leakage and freezing in winter ubiquitously. The piping system includes water leakage detection sensors (10a to 10n) and heating wires (27 and 37) for generating heat, installed inside open water service boxes (3a to 3n) and between double pipes (CD pipe and soft pipe), thereby preventing the freezing of the pipes in winder. Furthermore the piping system includes temperature detection sensors (25 and 35) installed inside of an outdoor water meter box (2) and one of the open water service boxes (3a to 3n), detects temperature upon attainment of a freezing point in the pipes, informs an operator of this, and supplies power to heating wires (27 and 37) installed in the outdoor water meter box (2), the open water service boxes (3a to 3n) and the double pipes, thereby preventing freezing in winter.</p> |
