In short: Plumbing expert Richard Trethewey demonstrates how to identify common drainage components, from standard white PVC to black ABS pipes, and explains the specific roles of different fittings.

In the U.S., drainage systems typically rely on white PVC pipes, which are available in sizes ranging from 1/2-inch to 5-inch, though black ABS pipes are also used. The video details the specific geometry of plumbing connections, such as using couplings for straight lines and selecting between 22, 45, 60, or 90-degree angles for turns.

The tutorial also covers complex junctions, including tees, wyes, and double fittings like the double tee or double wye, which can be used to connect multiple sinks to a single drainpipe.
