Pressure regulators are used to control and reduce system pressure in water, irrigation, and gas systems. These components play a critical role in protecting downstream systems from excessive pressure. When a regulator fails, it can allow elevated pressure to pass through the system, leading to damage that may not be immediately attributed to the regulator itself.
In this episode of Evidence to Answers, forensic engineer Mark explains how pressure regulators function and how they are typically installed within a system. He covers the importance of proper placement, support, and connection methods, as well as the impact of environmental exposure and debris on regulator performance. He also reviews the most common failure patterns seen in practice, including installation-related issues, environmental damage, and wear of internal components.
This video is for those involved in losses where a pressure regulator is a factor. Documenting system pressures, installation conditions, and component details before removal provides the context needed for a complete and defensible evaluation.
