course overview

The Plumbing Course is broken into four parts — supply piping, water heaters, waste piping, and plumbing fixtures. The physics of water is covered at the beginning in a simple, common-sense way.

You will also learn how systems work and common failure modes. Again, the illustrations add significantly to the learning experience.

Within each section are several Study Sessions to guide you through the material. The Quick Quizzes will help you check your progress.

An important and valuable part of a home inspection is locating the main shut-off valve, and showing the client where it is and what it does. It is from our Plumbing Course, Public Water Service chapter. All of our 10 Courses are richly illustrated.
