1. The construction materials are genuine and fake and the market is chaotic The problems with "hidden projects" are most obvious. At present, the building materials industry is developing too fast, a variety of materials coexist, and a wide variety of materials exist. A few companies or “guerrilla teams†have sought to make huge profits. They have not taken the trouble to fill in the truth and shoddy and make some counterfeit materials into the project. This is the result of the quality of the project. The most direct cause of the customs. Suggestion: Change the water pipe, what kind of water pipe is selected, decide the quality, hygiene and health of the water used in the house. The earliest were stainless steel pipes, galvanized steel pipes, then aluminum plastic pipes, then plastic pipes including PPR, etc. The latest is the thin-walled copper pipes that are connected with the world. The pipes have been updated several times. This kind of pipe listing will be greatly hyped, and then promised to use it for decades. In fact, some pipes have not passed the test of time. Some types of aluminum-plastic pipes have problems with internal materials and connection methods. When the pressure increases, it is prone to leaking or even bursting. At present, copper pipes are used most widely in the world. Copper pipes have obvious advantages in terms of resistance to high and low temperatures, strength, environmental protection, and hygiene. Therefore, at the scene, the owner must be clear about what texture water pipes are used. 2, construction violations, cutting corners Problem 1: The roof leakage caused by pipeline leakage is a prominent violation. Suggestion: At the scene, the owner must check the kitchen and toilet water pipes and heating pipes in each room. Whether the construction personnel perform water injection and pressure inspection according to regulations, if the workers do not check, they can directly hand over the work. It would be difficult to check it again because it is invisible and intangible after completion. If something goes wrong, it will be late. Question 2: When the line is installed, some owners or companies often ignore the phenomenon prescribed by the competent authority, such as unauthorized removal of pipelines; The wires were buried in the plastering layer without the use of PVC sheathed wires; some of them were covered with tubes, but the middle wire was twisted, joints, etc.; or the PVC tube was bent directly in the area where the bend was, without using the matching Elbow tool or matching elbow. Suggestion: The owner must be on site and must supervise the construction personnel to strictly abide by the regulations of “Fire Line Into Switch, Zero Line Into Lamp, Left-to-Right Fire, Grounded Onâ€. The buried line cannot be directly buried in the plastering layer, but the wire is placed in the PVC pipe. The main function is to protect and insulate it; another important role is to ensure the future maintenance. After the concealment works are completed, if a certain wire is out of order on a certain day, the wire can be pulled out through the PVC pipe and a good one can be replaced. If too many wires are pulled through the PVC pipe, there is no way to talk about future repairs. If the PVC pipe is bent directly in a curved place without the use of a matching elbow tool or a matching elbow, this will break the wire and it is very easy to cause an open circuit or even cause a fire. 3, hardware accessories, lamps, jewelry, etc., these are often easily overlooked in the process, or due to the owner to the late physical and mental fatigue and hastily. However, to achieve good results and a high standard of living, these details cannot be ignored. High-quality door hinges, slide rails, and ergonomic door handles give people a sense of not just staying on the visual enjoyment but deeper concepts when using them. If the position of the doorknob is not fixed, it is set specifically according to the nature of the environment. These inconspicuous details are where consumers are truly tested. 4. Many families choose to replace ordinary windows or aluminum alloy windows with plastic steel windows. There are also some problems that need to be spotted on site by the owners paying special attention: First, see if they are firmly fixed. The sand in the north is large, and some installers are not good enough. The fixing of the steel windows is not very firm. This will cause the original square window to be blown out of shape or tilted, making it more and more difficult to open in the future, or during the rainy season. Rainwater may flow into the room. Next, see if the cement mortar around the sealed outside window is tight. As the saying goes: “The large hole in the needle nose enters the big wind,†and there is no blockage around the window, making the room, which was originally well heated, leak into the cool air from time to time. 5, the owner can focus on the company's on-site management, to see how the project quality in the end, not a layman can do it. However, if on the construction site, to see what the sanitary conditions on the site, whether the bathroom is equipped with temporary toilets used during construction, whether the workers smoke on the construction site, whether there is anyone drinking during the work, whether the materials are put neatly, and whether the construction waste is cleaned daily. If the management of the construction site is in place and orderly, there will be no major problems with the company's construction quality. On the other hand, if construction management lacks the necessary training and the work done by the workers is not much better, then you must pay attention. 6, the owners can also focus on the responsibility of the company's construction staff. Because a well-run and well-operated company will complete every small project on the construction site as much as possible in the final acceptance stage, it will never use some legacy projects to recover the project's final payment from the owner.
