If you want to Learn plumbing, we can do it by two ways. First, you can learn it by online with following tutorial videos from plumbing course video. Not only learned about the installation or draining but also how to read blueprint correctly. It is very easy and we can learn it from home. Usually, this service is provided by plumber service company or training service for workers. The processes are also easy because we can set our schedule and adjust to the time we got.
Second, we can learn it by the practice. Some people have a great talent and not all of them realize it. Maybe, we can see the person who does not have a license of the plumber but he can repair the drains or radiator nicely. It means, he never participated in the training to get license and he got the knowledge about plumbing by self-taught or just observe the work of a plumber.
