Is the PPR water pipe divided into hot and cold water pipes? In fact, the PPR water pipe is divided into cold and hot pipes, and the high temperature resistance of the two pipes is different. Therefore, special attention should be paid to the installation of the cold and hot pipes. Otherwise, water leakage will occur. Generally, cold water pipes and hot water pipes are required to withstand pressure, so hot water pipes are thicker than cold water pipes, and the price is more expensive. In addition, the hot water pipe is marked with a red line, and the cold water pipe is marked with a blue line, and has a text mark and a pressure tolerance mark. It is also possible to distinguish hot and cold water pipes by comparing the wall thickness of pipes of the same specification.
