Plumbers are responsible for installing pipes, valves, and fittings in commercial or residential structures to ensure everything operates smoothly. In addition, plumbers analyze plumbing emergencies when necessary, fixing them if possible.

They also need to be proficient with a wide range of tools, from basic hand tools like wrenches and pipe cutters to more advanced equipment like pipe threaders etc. Additionally, they need to be aware of and able to follow safety procedures to protect themselves and others.
