In this video from our Building Systems Exam prep course, Mike Newman discusses the concepts behind Riser Diagrams and how they relate to the Building Systems Exam. The point of a Riser Diagram is to separate out plumbing systems to make them complex. As Mike points out, they are not necessarily to scale, but rather a representation useful for marking up and laying out when you need to break down things like pricing and relationships with other building systems. Mike will go further into this concept of Riser Diagrams and offer his unique insight into not only the thought process behind the Riser Diagrams, but what you need to understand about this concept when taking the exam.
