This architectural drawing is Sink pipeline design with detailing. PVC piping is generally used as part of a sink, toilet, or shower drain line, though it's sometimes used as a home's main water supply pipe. The ideal slope of any drain line is ¼ inch per foot of pipe. In other words, for every foot the pipe travels horizontally, it should be dropping ¼ inch vertically. For more details and information download the drawing file.
