How frustrating and worrying it can be to move into a newly renovated home with joy, only to find soon after that appliances are malfunctioning from time to time, or that there are inexplicable electricity leaks on the walls.
The root cause of these problems is likely to lie in the improper operation of plumbers during renovation.
Below, let's take a look at the "lazy practices" of hydropower workers in the renovation that may bring endless troubles.
1. The wires are bare and buried in the wall
Many people may think that as long as the wires can be energized, it doesn't seem to matter where they are buried. But in reality, this is an extremely dangerous misconception.
The wires were buried in the wall as if they were a time bomb.
On the one hand, over time, the humidity and temperature changes of the wall, as well as the influence of various external forces, can cause damage to the insulation layer of the wire.
If the insulation is broken, current leaks out, which not only increases the risk of electric shock, but can also cause serious consequences such as fire.
Moreover, when you want to renovate or renovate the house, it is impossible to determine the specific location of the wires in the wall, and the slightest carelessness may damage the wires and bring more trouble to yourself.
2. There are too many wires in the threading pipe
Some plumbers will cram too many wires into the conduit to save trouble, or to save material.
This may seem like a space and cost saver, but it actually brings a lot of hidden dangers.
Too many wires crammed into one conduit can lead to poor heat dissipation.
The wire will generate heat when it is working, and if it cannot be dissipated in time, it will increase the temperature of the wire and accelerate the aging of the insulation layer.
In the long run, the service life of the wire will be greatly shortened, and it may even cause a fire in an inadvertent moment.
In addition, too many wires will also increase the burden on the conduit, making it easy to deform and break, further affecting the safety of the wire.
3. There is no separation between strong and weak electricity
In modern families, there are more and more devices with strong and weak currents, such as lamps and sockets, which belong to strong current equipment, while network cables, telephone lines, TV lines, etc. belong to weak current equipment.
If the strong current and the weak current are not laid separately, the electromagnetic field generated by the strong electricity will cause interference to the weak current signal.
You may find that the internet signal at home is up and down, the TV screen is full of snowflakes, and the phone is full of noise.
This will not only affect our daily life, but it may also cause damage to some delicate electronic devices.
Moreover, strong current and weak current are mixed together, and once the strong current fails, it is easy to affect the weak current equipment, increasing the safety risk.
4. The wall is opened with horizontal grooves
During the renovation process, it is sometimes necessary to make grooves in the walls in order to lay wires and water pipes.
However, the transverse groove will cause greater damage to the structure of the wall.
The wall is like the skeleton of a house, and the transverse groove can weaken the load-bearing capacity of the wall, especially in some earthquake-prone areas, which can pose a serious safety hazard.
In addition, the transverse groove is also easy to cause wall cracking, affecting the aesthetics and service life of the house.
5. There is no obvious distinction between the three lines
The so-called three wires are the live wire, the neutral line and the ground wire.
Under normal circumstances, these three wires should be clearly color-differentiated for easy installation and maintenance.
If there is no obvious distinction between the three wires, it is easy to connect the wrong wire in the future use process.
Once the wrong wire is connected, it may cause the appliance to not work properly, and even cause an electric shock accident.
In addition, when carrying out maintenance, it will also increase the difficulty and risk of maintenance because it is impossible to accurately judge the role of the three wires.
6. The strong and weak electricity cross is not wrapped in tin foil
Although in some cases, strong and weak electrical crossover is unavoidable. However, if not handled properly, it can be a serious disruption.
Tin foil is a common solution that can effectively reduce the interference between strong and weak electricity.
However, some plumbers may wrap tin foil in a perfunctory way, or not at all, in order to be lazy.
In this way, the interference between strong and weak electricity cannot be effectively controlled, which will bring a lot of inconvenience to our lives.
In order to avoid the consequences of the "lazy practice" of these hydropower workers, we must strengthen supervision and management in the decoration process. If you don't know much about hydropower projects, you can ask professional supervisors to supervise.
