What Skills Do You Need to Be a Plumber?
Selected Excerpt:
Acquired Skills
Because plumbers are often required to make precise measurements, they should have a grasp of basic mathematics; a knowledge of geometry and algebra is also helpful. Plumbers should have adequate oral communication skills to speak with customers to gain an understanding of their plumbing problems and explain what needs to be done to resolve them. Knowing what tools, machines and methods are best for each situation means learning certain mechanical basics, such as whether a repair method will hold up to the water pressure to which it will be subjected or if a material can be safely cut with a specific tool. Certain jobs require the ability to read and follow blueprints to determine where pipes and equipment should go. Plumbers should also know the local codes that apply to various types of jobs so they can comply with the regulations.
