Precautions for the installation of PPSU fittings: First of all, the joint needs to be suitable, and the joint and the water pipe do not overlap, which will directly lead to the rupture of the water pipe or the damage of the joint. This seemingly simple problem is actually ignored by many people, especially in winter, some people think that it is a problem of internal thermal expansion and contraction. Before installation, you need to check the pipe fittings and joints to find the corresponding joints and pipe fittings. In addition, it is strictly forbidden to bake with fire. In winter, some workers often use an open flame to directly bake the water pipes and then splicing, which is inappropriate. Because the open flame baking will cause uneven heating of the water pipe, which will directly cause the water pipe to rupture after installation. A professional pipe expander is required, which is simple and easy to operate. Then there is the issue of the reserved length of the water pipe. Some people cut the water pipes first, then connect the joints, and finally found the problem that the water pipes were not long enough. This is caused by cutting the water pipe directly without actual measurement. There are many details in the actual installation, which need everyone's attention.
