Where should flexible connectors be installed according to best practices?

Flexible connectors play a crucial role in underground storage tank (UST) systems by accommodating movements caused by settling or expansion and contraction due to temperature changes. Installing flexible connectors at multiple critical connection points is considered best practice because it enhances the system's overall integrity and resilience.

These critical connection points typically include the connections between the tank and the piping, as well as at dispenser locations. By utilizing flexible connectors at these various junctions, the potential for stress on rigid piping and connections is reduced, which minimizes the risk of leaks or failures that could arise from ground movement or thermal expansion.

This installation strategy not only ensures better functionality of the UST system but also complies with safety regulations and best industry practices. Thus, having flexible connectors at multiple critical points is essential in maintaining the reliability and longevity of UST systems.
