Point one: waterway direction problem
If the water pipe is not properly planned, it is easy to affect the follow-up decoration works, and the installation of family waterways almost go dark, it is recommended to go to the top. On the one hand to avoid man-made damage: on the other hand, once the pipeline leakage can also be found in time, but also convenient maintenance, less loss. Of course, the top of the pipeline installation is more difficult, material is also more, according to the actual situation to consider
Point two: cross laying mode
Pipeline laying is very complicated, it is inevitable that some pipelines need to be cross-laid. If there is no cross special pipe fitting to undertake, the pipe fitting above will explode under the action of gravity for a long time after pasting brick or leveling. At this time, the use of bridge four to undertake is a good choice
Point three: Pay attention to the way the water pipes are connected
PP-R water supply pipe is generally installed by hot melt welding, and the connection is more firm. There are no special circumstances, and there will be no leakage phenomenon for a long time after the water is used. However, in the bathroom, the kitchen this frequent water, more prone to failure of the area, you can consider the use of live connection, more convenient later disassembly and maintenance.
Point four: hot and cold water pipe dark installation
Many people will encounter hot and cold water in the process of using water. In addition to the problem of electrical equipment itself, it is likely that the distance between hot and cold water pipelines is set too close in the process of laying
Another point to note, hot and cold water pipes to distinguish. PP-R cold water pipe has relatively low bearing capacity at high temperature (recommended below 40°C), so it is not suitable to be used as hot water pipe; otherwise, pipe explosion may occur. The long-term use temperature of PP-R hot water pipe is not higher than 70°C, otherwise it will affect the service life of PP-R hot water pipe, so we should also take this into account when setting the hot water temperature
