Beginning the tracing of a system at the reservoir is essential because it serves as the primary source of fluid, whether it’s water, oil, or any other substance being transported through the system. Starting at the reservoir allows you to understand the overall function and dynamics of the entire system since all flows originate from this point.

Tracing from the reservoir also enables you to identify the direction of flows, pressure changes, and potential issues that may arise downstream. This holistic approach can provide critical insights into how the system operates and how various components interact with one another. By beginning at the source, you ensure that no key elements are overlooked, making it easier to follow the path of the medium through the system and to troubleshoot any problems effectively based on the system’s configuration.
