How to decorate water and electricity
1, horizontal and vertical
Horizontal and vertical is not only neat and beautiful, but also convenient for future maintenance and inspection. But some people will say that this will waste materials, gas and water, and the water heater will take a long time to get out of the water, and the water pressure will become lower. Moreover, this requires many turns, and threading may encounter resistance in the future.
2. Two points and one line
Two points and one line, although not very beautiful, can save materials and costs, less dead corners, can reduce dead corners, anyway, it is a concealed project, no matter how beautiful, as long as it is sealed, nothing can be seen.
In the later stage, nails will be nailed to the wall and the ground, which will probably puncture the wires or water pipes, leading to the problem of water leakage or bursting of the water pipes, so we can't think that the small cost in the early stage will cause big problems in the future.
What should I pay attention to?
1, it is best to indicate the brand of wires used for circuit transformation in the contract.
2, the switch of the whole house should be basically in the same horizontal position.
3. The sockets in the whole house should be in the same horizontal position as far as possible, except for special sockets such as air conditioners and refrigerators and those with special requirements.
4. The colors of phase line and zero line in circuit transformation should be consistent in all rooms. If possible, it is best to indicate the colors of live wire, zero wire and control wire in the contract, and the protection wire is yellow and green according to national regulations.
5. It is best to use 3 wires with more than 4.0 strands for socket wires (including air-conditioned refrigerators) and 2 wires with more than 2.5 strands for lighting wires.
6. The bottom box is buried underground. If possible, you'd better buy the bottom box yourself. Please report the installation fee to the decoration team.
