The term plumbing refers to the use of devices like valves and pipes so as to convey a fluid from one point to another for a wide range of applications. The plumbing knowledge is helpful since it helps solve health-related issues and maintain high standards of sanitation. In major incidences, the plumbing devices are hidden behind utility spaces and walls making them invisible from anyone. Examples of common devices that are used during the plumbing activities include no return valves, water filters, water heaters, pumps, water softeners, water meters and their control systems. A plumber uses a combination of several tools such as pipe wrenches, piper cutter, bending machine and tools that are used for joining purposes such as the crimp tools.
