Unit II: Installing Water Supply Systems

About this Unit

A plumber must have the ability to join and install different kinds of pipes that can be used to complete the water supply pipe system of a building. These pipes are made of different materials, and many times they will have to be cut and their ends prepared for fitting connections to form leakproof joints. These connections are made with threaded joints, fused joints, and compression joints depending on the type of pipe. As the pipe system is installed with fittings, it must be supported with hangers and holders. Many times a plumber must cut into the building structure to place water supply pipeline runs to service all lavatories, sinks, and water closets that are to be installed. The plumber also tests the rough-in water supply pipeline system for leaks when it is completely installed.
