In the decoration of family homes, disputes over water supply and drainage pipes account for a large proportion of quality complaints. The only way is to strictly follow the process requirements to ensure the quality of the project. The construction personnel should hold the certificates and never allow subcontracting the hydropower project to the guerrillas on the road. After the completion of the project, the industry is mainly responsible for acceptance. After passing the inspection, it can enter the next process to continue operations. Therefore, the owner must understand this knowledge.
If there is a quality problem in the water supply and drainage pipeline project, there may not be water leakage at that time, but it will take a long time, and it will undergo cold and heat expansion and water pressure. The pipeline will leak or even burst, causing serious consequences. Such an instance is not an isolated phenomenon. Therefore, the Shanghai local standard “Residential Decoration Acceptance Standard†imposes mandatory implementation of the engineering quality requirements for water supply and drainage pipeline construction. In other words, the water supply and drainage pipeline project must comply with the standard requirements. According to the standard requirements, the drain pipe should use rigid PVC drainage pipe and connectors. Should choose the manufacturer's name, brand, specifications and models of qualified products. Don't go to a street shop to buy three products, because the plastic pipes look almost the same, but the quality is actually very different. Some companies add a large amount of waste to reduce costs, return materials, and greatly reduce product performance and life expectancy. The use of such pipes is equivalent to the time bombs being planted in the room. I do not know the day when the pipeline will suddenly burst and the water in the room will be full of people.
The water supply pipe shall be provided with exposed threads at its joints with a threaded connection. The pipe clamp shall be used for the timely installation of the water supply pipe. The connection between the pipe and the pipe fitting or valve shall be firm and shall not be loosened. After the pipeline is installed, check the water and check for leaks by visual inspection and feel. Check all the faucets, whether the valve is installed flat, whether the opening is flexible, whether the water is open and whether there is leakage. Check if the water meter is working properly. After the above inspections are done, the pipeline can be closed for the next process. For special circumstances, special care must be taken to avoid causing future problems. For example, the pipeline is very long, connecting the kitchen and the bathroom, or leading to the balcony. The pipeline must pass through the living room or the room. Since the pipeline is not buried in the wall or is laid under the floor, the consequences will be serious if there is a problem, so there should be no joints in the middle. And to properly enlarge the pipe diameter to avoid clogging. The hot water pipeline shall not use galvanized iron pipes to prevent the pipes from rusting and generating scale, and heat insulation measures shall be taken.
