What are the common problems in decoration and hydropower construction in life?
1, water pipe leakage: assuming that there is no quality problem in the water pipe and the pipe body itself, both the cold water pipe and the hot water pipe may leak. The leakage of cold water pipe is generally due to the seal failure when the water pipe is connected with the pipe fitting; Hot water pipes leak, in addition to poor sealing, there may be improper selection of sealing materials.
2. Reasons for low water flow: During construction, in order to connect the whole line, the sawed water pipe should be threaded. If the thread is too long, the water pipe will be screwed into the pipe fitting (such as elbow) too deeply when connecting, resulting in a smaller cross section and smaller water flow.
3, hose burst: most of the pipes connecting the main pipe and sanitary ware use snake-shaped hoses. If the quality of the hose is poor or the plumber screws it tightly during installation, it will burst after a period of use.
4. The toilet overflows when flushing: When installing the toilet, the groove of the base is not sealed with grease, and sewage will overflow from the gap between the base and the ground when flushing.
5. When the washbasin is put into the water, it will smell back: In the renovated bathroom, the washbasin is often moved to the wrong position with the water inlet, and it is often difficult to use the sewer pipe directly with it when buying the washbasin. In order to save trouble, the installer generally does not make an S-bend, which leads to the direct connection between the washbasin and the sewer, and the smell returns from the sewer.
6. There are too many line connectors, and improper handling of connectors is the main reason. Some lines are too long, and electricians will have some joints when operating. However, due to the limitation of electrician technical level of some construction teams, wiring, insulation and moisture-proof treatment of joints are not good, and there will be open circuit and short circuit.
7. Cut corners to reduce costs, and there is no casing for the concealed wire.
8. The completed line is damaged by the subsequent construction. For example, the wall line is interrupted by the electric hammer, and the air nail gun penetrates the PVC conduit or sheath line when laying the floor.
9. The distribution line does not consider the different rated currents of wires with different specifications, and the "small horse-drawn cart" leads to the long-term overload of the line itself.
10, different lines take the same conduit. If the TV antenna, telephone line and distribution line are inserted into the same housing, it will interfere with the reception of TV and telephone.
