How old is a plumber?

Our life is getting more and more comfortable now. If we want running water, we just need to turn on the tap. When it is dark, we can turn on the lights to light up the whole room. Some places even supply hot water 24 hours a day. Of course, now all comfortable life can not be separated from the silent efforts of some people. Let's talk about plumbers today.

Many people don't know much about plumbers, so I'll describe them like this. The plumber is equivalent to the old fitter in the workshop in the capital construction work, and basically contracts most of the craft work. This metaphor is very vivid, which can intuitively reflect that the skills needed by plumbers are still very strong. Even many plumbers are almost 30 years old and just apprentices. Because there are many credits involved, I think this job is suitable for studying in my early twenties, and it is only suitable for my thirties.

The reason why it is so difficult to learn is that there is a lot of knowledge about piping, including corrugated pipes, plastic pipes, hoses, explosion-proof pipes, wire tubes and steel pipes. Basically, they laid all the pipelines related to infrastructure projects. If it is laid with open pipes, it is relatively simple and easy to learn. The most difficult thing to learn is the laying of concealed pipes, which requires very high technology. Whether laying open pipes or concealed pipes, all aspects should be considered, such as convenience and safety. Therefore, this job is more suitable for people in their thirties and forties, with more careful thoughts and thoughtful thinking.

For the simplest example, if there is a liquefied gas pipeline laying next to it, it is definitely not allowed to lay circuit pipes next to it. Of course, this is the simplest knowledge, and there are many complicated knowledge that need to be studied for many years to master.

In addition, plumbers should not only master their own knowledge, but also master the knowledge of other industries, such as the most basic electrician knowledge. They should not only lay pipelines, but also be responsible for the most basic switch box, distribution box, power connection box and lamp holder control box. The installation of these circuits needs many years of precipitation, so I think people in their thirties can master at least so much knowledge.
