<p>This Architectural Drawing is Pipeline path layout of washroom. A toilet drain pipe runs into a home's sewer main, which is <strong>the pipe that carries all the sewage in your home out to the city or municipal waste system</strong>. When two ends of pipes are joined, the pipe fitting used is called <strong>union</strong>. A union is made of three parts namely a nut, a male end and a female end. The male and female ends are assembled with the support of the nuts, and necessary pressure is made to connect the joint. A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly <strong>to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids</strong>.
