This problem should be solved in the north and south of China. China has a vast territory and rich resources, and there is no floor heating equipment in the south. So, we don't have to think about it. There is floor heating in the northern area, which must be done before decoration. If it is not a concealed work after installation, once there is a problem of overheating and water leakage, you will not be able to solve the cost, or you will have more trouble. Therefore, pressure test should be carried out first, and then decoration should be carried out. Before the construction, the owner, the property management company and the decoration company were all present, which lasted for six hours. You can take photos to let the property leave.
Then carry out construction under pressure, so as to standardize the construction personnel, especially the ground construction. Once the pressure gauge drops sharply, the owner will soon know that there must be something wrong with the pipeline. After completion, the floor heating system is a concealed project. After the installation, the surface layer (leveling layer and heat storage layer) can be constructed only after the pressure test is qualified. If the geothermal coil is found to be leaking in the later stage, only destructive measures can be taken for maintenance. The pressure gauge will definitely drop by one grid, which is normal wear and tear. Please bring the property to the site and suppress it. The instrument does not drop for half an hour, indicating that the pipeline is not damaged during construction. If the three parties are not at the scene, there will be problems, and the decoration company and the property will shirk each other, and the owners will suffer.
