This Architectural drawing is Waste and soil pipe line of Toilet. A soil pipe is a pipe that conveys sewage or wastewater reliably, either from the toilet or sink to a soil drain or sewer. They are relatively easy to spot as they run vertically from the underground drainage system to the top of a property, where they reach the roof gutter. A waste pipe is a pipe which is designed to carry away liquid waste, with the exception of sewage, which is handled by different plumbing for reasons of environmental health. In homes, waste pipes drain washers, sinks, dishwashers, and other plumbed fixtures. The most simple way to connect a waste pipe to an existing soil pipe is to install a 'strap on boss' (pictured at the top of the article) to make a watertight connection. Simply cut a hole in the soil pipe and place the strap around the exterior of the pipe. Soil Pipes are designed to transport the soiled water (blackwater) from your toilet, urinal, or bidet (if you're fancy). Waste Pipes are designed to transport the wastewater (greywater) from your sinks, shower, bath, washing machine, or dishwasher. For more details and information download the drawing file.
