Which standard drainage pipes should be used in the construction of drainage pipes? Rigid PVC drainage pipes and joints should be selected. Eligible products with the title, brand, and specification of the drainage pipe manufacturer should be selected. In order to reduce costs, some companies add waste materials and return materials, which greatly reduces product performance and life expectancy. The use of such pipes is tantamount to burying a time bomb in the room. Don't just go to the small street shop to buy Sanwu products, because the plastic pipes look similar, but in fact the quality is very different. After the piping equipment is completed, it is necessary to review the water flow, and check whether there is leakage by visual inspection and feel. Check whether all faucets and valves can be flat, open and flexible, whether the water can be dredged, and whether there is leakage. See if the water meter is working properly. After doing the above introspection, you can close the pipeline and proceed to the next process. The ribbed joint selected for the water supply pipe should have ribbed at the joint. The equipment should be consolidated with a tube card immediately after the end of the equipment. Because the pipeline is either buried in the wall or laid under the floor, once the results appear, the effect will be serious, so there should be no comments in the center. Moreover, the diameter of the tube must be appropriately reduced to avoid infarction. Hot-water pipelines must not use galvanized iron pipes to avoid water pipe corrosion and scale outbreaks. Insulation steps must be used. To resist some special circumstances, we must take care to deal with it, so as not to cause future troubles. For example, the pipe is very long, connecting the kitchen and the toilet, or leading to the balcony, the pipe must pass through the guest room or room.
