Hydropower engineering is a hidden project in our home improvement. For the sake of a comfortable life later, the pre-hidden project must not be careless.

Experts remind you that in the home renovation, electric construction seems to live a lot on the surface, but many potential problems leave many hidden dangers for future life. The common problems are: short circuit of the distribution line, weak television signal, and interference from telephone reception.
There is a problem:
1. The main reason is that there are too many line connectors and improper handling of connectors. Some lines are too long. Some joints will be produced during the electrician's operation. However, due to technical limitations of some of the construction team's electricians, the wiring, insulation, and moisture-proof treatment of joints are not good, and disconnection, short circuit, etc. will occur.
2. To reduce the cost of cutting corners, the wiring for the concealed treatment is not sleeved.
3. The completed line was damaged by subsequent construction. If the wall line is interrupted by an electric hammer and the floor is paved, the air nail gun penetrates the PVC pipe or sheath wire.
4. The distribution line does not take into account the different rated currents of the wires of different specifications. The "small horse-drawn cart" causes the line itself to be overloaded for a long time.
5. Different lines go the same line. If the television antenna, the telephone line and the distribution line are threaded into the same casing, the reception of the television and the telephone is disturbed.
Plumbing series
After you move into your new home, you may find water-related quality problems. Such as leaking water pipes, odors in wash basins and vegetable sinks, small bathtub showers, and inconvenience in the use of sanitary ware.
There is a problem:
1. Pipe Leakage: Assuming there are no quality problems with the pipes and the pipes themselves, cold water pipes and hot water pipes may leak. Cold water pipe leakage is generally sealed when the water pipe and pipe fittings are not connected; hot water pipe leakage is not done in addition to the seal, but also may be improper selection of sealing materials.
2. The reason for the small water flow: During the construction, in order to connect the entire line, it is necessary to put thread on the sawed water pipe. If the thread length is too long, when the pipe is screwed into the Pipe Fitting (such as elbow) too deep, it will cause The cross-section of the stream becomes smaller and the water flow is smaller.
