All UST systems and their ancillary equipment must be compatible with the liquid to be stored in the tank. All components must be maintained and repaired, or replaced when required, in accordance with the manufacturer’s requirements.
The next three pages contain a diagram for three typical UST systems. They show the arrangement and placement of various components. Each component is labeled on the diagram. When you click on the name of a component (e.g. Drop Tube) a popup window will display showing a picture of the component and a description. The Certification Exam will have questions about these components and the UST system.
