Renovation inspection is very important to accept the neglect of the project

The concealed project is a project that is not easy to see as its name implies. It includes such items as waterway reconstruction, circuit transformation, ceiling structure and bathroom waterproofing. In general, the owners do not understand the materials used in concealed projects, the routing of waterways, the orientation of circuits, and the location of functional outlets. Because after the handover, these projects were buried in the walls, but the owners At least the following situations must be understood.

First, the waterway. Ordinary real estate waterways are usually three kinds, tap water, hot water and medium water. Reclaimed water is non-potable water, which is used for collecting and utilizing rainwater. It is generally used to flush toilets or watering flowers. Consumers need to know if hot and medium water are available and whether they are connected to the wrong pipe, and check the location of the water meter (should be in the kitchen or bathroom outlet). In addition, the material of the water pipe is directly related to life and must be determined as a qualified material designated by the country. If the water pipe material is too bad, it is easy to leak water later. The best water pipe material is copper pipe, and PPR pipe imported from Germany is also good.

Second, the circuit. Circuits refer to the location and matching of outlets, the type of wire, and the capacity of the largest consumer. This requires consumers to ask the property management company or developer in their community for the basic drawings of water, electricity and other concealed works. In the future use, if there is a short circuit or water cut, it can be repaired by a professional according to the drawings. In addition, it is necessary to observe whether the leakage protection switch of the distribution box has lighting; whether there is a clear shunt for ordinary sockets, high-power sockets, etc.; whether the installation of the panel switch is smooth; and whether the switch is valid.

Third, ceiling. The structure of the suspended ceiling is not shown on the as-built drawings, but the structure can be seen on the side of the hardcover room, the lamp position, or the ventilation of the central air conditioner. Ordinary owners can visually judge from the ceiling of the ceiling. According to relevant regulations, light steel keels must be used for concealed ceilings. The previously used wooden keels themselves contain water, which may have contraction changes in the four seasons, especially after heating in winter, and have been eliminated. The performance of the light steel keel is very stable and the service life is relatively long.

Fourth, waterproof. In the bathroom pour clear water test, check whether the water is smooth, such as the lowest point of the floor drain can not have stagnant water, the water should be smooth water.

In short, as long as we pay attention to these hidden projects, there will be less opportunities for problems in the future, and it will be possible to avoid the situation of reusing time and resources to reconstruct manpower and material resources.
